Title: HAL's MS-3 Music Server and dspMusik 6x8 DSP crossover and HiRez DAC's
Post by: HAL on 31 Jan 2015, 10:27 pm
The latest HAL MS-3 Music Server is now available. 

The unit looks identical to the MS-2, but the motherboard has been changed to an Intel Atom N2600 based with no cooling fan for even lower heat dissipation since the original Intel Atom N2800 motherboard is no longer available.  The unit is entirely solid state with the exception of the DVD drive for CD music ripping to the system library. 

The first production MS-3 was with VivaHiFi in Vienna, VA for a period of time recently while their HAL MS-2 Music Server was being upgraded to Windows 8.1 OS.  Feedback was very positive from Scottdazzle on AC. 

Along with this unit a new 6 input, 8 output DSP crossover and HiRez DAC combination called the dspMusik, is also available.  The unit uses 40bit floating point DSP based processing.  Has S/PDIF, USB2 asynchronous and 24bit/192KHz A/D inputs.  The unit has 8 channels of 24bit/192KHz D/A conversion.  All analog inputs and outputs are balanced via TRS connectors.  Both Mogami and Monoprice make TRS to XLR balanced cables to connect the unit to the audio system.

The dspMusik can also be used as a USB Class 2 audio DAC.  I have already done the software load for that and it can act as a stereo DAC with four stereo pairs.  The USB2 input is ASIO compliant and a custom PC USB driver is installed on the MS-3 or any Windows OS. 

The unit is custom programmed by HAL for the customer speaker crossover requirements.  This is to make the unit plug and play for the customers system.

The first demo of the latest version of the DSP crossover was at CES2015 in January.   The latest demo is going on with the VMPS RM50 speakers that were used at one of THE SHOW events for the live vs recorded event by VMPS.  The speakers were developed with the Behringer DCX2496 digital crossover as part of the system.  The dspMusik was custom programmed to replace the DCX2496 with a minimized signal processing path.   

Since there are VMPS owners that have DCX2496 units in their system, this is an alternative to that system.  Other speaker systems are a possible alternatives that use the DCX2496 as their crossover system.  New speaker designs are also in the works using this as the full crossover system using direct powered drivers.

Pricing is:

HAL MS-3 Music Server running Windows 10 Home 64bit OS  $799.00 + s/h
Danville Signal Processing dspMusik DSP crossover custom programmed system with HAL MS-3 $2299.00 + s/h

Please post questions in this thread if you have any.  For reference the HAL MS-2 thread is on this Circle as well.

Rich - did you get my PM from the other day?  Interested in the MS-3.  My question was just about the size of the unit and was it identical to the MS-2 (and I guess since I have an MS-2, the server name needs to be something other than HALMusic).  Thanks.

Phil,
Yes the MS-3 is the identical chassis to the MS-2.  Only a few connectors locations have changed on the back.

Let me know whatever name you want and I can do that during the OS load.  I just call them that for lack of input.

I have some parts on order and can get a chassis when you want it.

Rich - all I need is the model (again) of the wireless keyboard you recommend (so I can order one and have it ready).  'HALMusic2' is fine.  I have an old 42 inch Vizio in the room already with a PC input and I picked up a cheapo Android tablet anyway recently as I needed it to select music attached to the Oppo BDP-93 in the bedroom system which feeds the outdoor speakers.  So just let me know and I can get you a payment and we can start the process.

Just looked at the keyboard on my MS-2 which is this one - http://www.amazon.com/Logitech-Wireless-Keyboard-Multi-Touch-Touchpad/dp/B005DKZTMG/ref=sr_1_1?ie=UTF8&qid=1422745378&sr=8-1&keywords=logitech+k400&pebp=1422745371727&peasin=B005DKZTMG

Is this still what you recommend?  It works fine on the MS-2 just asking if in your experience you have found something that you like better.  Thanks.

Phil,
Yes, the Logitech K400 is what I use and recommend as in the link.  I find them at Best Buy stores on sale for $25. 

I am just glad that you still enjoy the MS-2.

If you still have my email address, that is the PayPal one to use.  I just have to know your new address for shipping, so you can send that in the email.

Rich,
Good to hear about the MS-3. I hope to see you sometime soon in this new year. I do miss Southern MD as well and would love to visit. I owe Bunky a trip down there also.

I still keep my eyes and ears open for a used Hi-Face EVO should I ever need an interface to run with my Non-USB DAC. The EVO is still a hard animal to come across used. That combo worked amazingly well with the MS-1 in my system. Though I am not completely ignorant of the advances that have been made in the last month, or year, or two.

Oh Darn. I probably am for the most part. I need to spend more time on research. And less on the other hobbies which offer less return. :duh:

I would miss the lovingly crafted wooden top cover that graced the first model. Although we can all customize our components. As long as we don't impede cooling or other important functions.
Note: My system pics still have the MS-1 featured and it looks as good as it sounded.

Phil A.,

Clearly we miss you and I should plan a trip to FLA (sounds like the late Lou Reed). I still have the Microsoft Wireless Combo
I used with the MS-1 on a shelf here. Good combo. Unless you're like my MAC pal who thinks Bill Gates is the Antichrist. :nono:

James,
I have the same feeling about MAC's!   :lol:

Looking forward to another MAAC gathering at some point to see everyone again. 

Alas the MS-1 chassis is no longer available.  At least the MS-3 has no fan for zero mechanical noise when you are not using the DVD drive. 

The dspMusik DAC's are very good.  My initial testing was just as a USB2 asynchronous DAC to make sure it sounded good enough to proceed with the crossover part.  It did a fine job.  Woodsyi and Pez got a chance at RMAF2014 to give it a listen.  Since then power supply improvements have made it sound even better. 

I have been working on a Open Baffle Speaker Project for possible Recording Studio use.  The dspMusik is the heart of the design with powered speakers.  The first design is working.  Planar mid and tweeter with 8" OB servo subs.  Sounds good and measures well.  Still a way to go. 

Maybe a MAAC gathering when I have it working will be possible.

Ok, the MS-3 parts for PhilA are on order. 

Demo this week of both systems, so will see what happens on the second in home trial. 
Title: Re: HAL's MS-3 Music Server and dspMusik 6x8 DSP crossover and HiRez DAC's
Post by: HAL on 3 Feb 2015, 04:18 pm
One other piece of the dspMusik digital crossover idea is that since I program the unit, I remove all unneeded signal processing blocks that most of the generic DSP crossover need to allow users to adapt them to their system.  This is already adapted for the user when it is installed.

From my listening trials this increases the sound quality of the system.   
Title: Re: HAL's MS-3 Music Server and dspMusik 6x8 DSP crossover and HiRez DAC's
Post by: HAL on 4 Feb 2015, 12:22 pm
The dspMusik is also a very good DAC for HiRez file replay up to 24bit/192KHz.   It uses the minimum phase apodising filters in the Wolfson DAC. 

In work at this time is control software to use the Wolfson DAC digital volume controls across all four chips simultaneously for overall volume control.  This would replace the need for a preamp in a very simple setup for digital music, or analog input.   

You can purchase a bundle with the HAL MS-3 and dspMusik for just use as a HiRez DAC for $1999.00.   The software in the dspMusik can then be upgraded at a later time for digital crossover use if needed.  The DSP crossover upgrade will be $400.00 at a later date.

Looking forward to his feedback.

Post by: HAL on 4 Feb 2015, 10:57 pm
Here is a comparison of a 8" full range drive in a open baffle U frame with 3x8" servo woofer being driven by the dspMusik.  The red graph is the unEQ'd speaker.  The green graph is the same speaker running EQ to correct the response plot.  There is no correction added to the dip at 13KHz.

Using two channels of the unit, one with the EQ for the 8" full range and direct couple for the 3x8" servo woofers.

All processing is with the 40bit floating point 192KHz sample rate software.

No linear phase filtering is used in the EQ or DAC outputs.

A discussion about room mode EQ.

Adding parametric EQ bands to the dspMusik is very simple to do.  Room measurements are needed for the speaker to add the correct parameters to set them up. Measurements that need to be done with the speakers in position and at the listening area.

One way to do this is using a method described by the Boston Audio Society for making multiple measurements in a 1 foot cube where the listeners head would be located.  Then average all the measurements to get the final EQ data at the listener position.

Since the dspMusik is also acting as the crossover, adding the PEQ to just the bass driver will keep the mid and tweeter path clean of the extra signal processing normally present in other units.  Any difference in processing time delay can be corrected for by adding bulk delay to the faster processing path channels.  No processing, just memory transfers all synchronized to the master low phase noise clock. 

This is one of the ideas for future development using the same dspMusik hardware.

The MS-3 and dspMusik are installed in woodsyi's setup and new digital crossover design done after we setup. 

It is replacing a Marchand active analog crossover for his VMPS RM40's for the demo.

Looking forward to his listening impressions once he has more listening time.

Here is what an example of the dspMusik block diagram used to program the system looks like.  Each block has parameter settings to customize it.  It is a fully drag and drop block diagram compiler for the code.  Connect the blocks and then download to the dspMusik.

Going to install Room EQ Wizard on the next MS-3 chassis that arrives and try the calibrated Dayton Audio UMM-6 with Windows 10.  If that works, an easy way to look at the room response to see how to setup the Parametric EQ's for low frequency room mode correction. 

Should be able to run both programs and transfer data points to the PEQ blocks on the fly.

Have one of the UMM-6 USB mics here to try out with the setup.

So you can see the relative size a bit better, below from my gallery it (my MS-2 and I should have the MS-3 for my secondary system in 3-4 weeks give or take) is sitting on the right hand shelf next to my Modwright preamp and my center channel is next to it on the middle shelf.  The case is about 8x8 inches and about 2.5 inches high.

The second HAL MS-3 and dspMusik digital crossover install is completed and running.

This is being used with a pair of GR-Research N2X and DIY subs. Being used with the S/PDIF connection, USB2 and A/D connections to a ProTools PC for mixing and monitoring recordings along with music replay in a home studio. 

The turntable setup is being run through the 24bit/192KHz A/D converter. 

The demo also includes comparison to his existing Music Server as a possible replacement.

The person demoing the unit also does recording and mixing and uses this system as a home studio and for listening purposes. 

Looking forward to dpd's and woodsyi's feedback.

Next trials will be to remote control the dspMusik using Microsoft Remote Desktop on a Surface to control the MS-3 operation. 

The user can already remotely control Foobar2000 using the webpage from a web browser.

Reports from JRiver using their remote control are also good.

Sent some updates to woodsyi's dspMusik install.  He did the updates this evening.

Did some parameters changes based on Pez's RM40 crossover. 

Changed out his USB2 cable for a Virtue Audio 1 meter USB2 cable for better high speed communications compared to the generic cable.

Also changed the single ended cables for the woofer channels to balanced.

Looking forward to his observations.

For Sure, Thanks for the pictures. Especially the new avatar. 8) More color than the last one. Must be the Florida Sun.

Good to see the main system again. How is the sound compared to the old room? It was stellar there.

Quite the slim package is the MS-2 and MS-3 from what I see. Knowing Rich, the sound is divine. I am looking forward to the
comparisons in sound over the three units. And of course it will be great to see you as CAF will be here before we know it.
BTW, we had whiteout conditions earlier this evening and are expecting 60 MPH Gusts :roll:

Hopefully I can finagle an invite to Rim's to hear the new server. Hint. Hint. And he will be kind (and patient) enough to explain
the advancements in the MS-2 and 3.

James,
The MS-3 Music Server is an Intel N2600 based motherboard that has no fan.  Lower power than the MS-2 motherboard.  The chassis, memory and SSD are the same. 

There are two USB2 controllers.  I recommend using the rear ports for the DAC and front ports for the other devices.

One option is to connect the eSATA port used for the DVD drive to an external hard drive for faster disc access like the MS-1.  This is if the unit will not be used for ripping CD's.

Those are the basic differences.

James, have not done tweaking yet.  I did not get the system together until the end of August.  I have Sonic Saucers for the spikey feet at the bottom of the speakers that have yet to go on.  Been bugging Meitner for the new firmware so I can crawl back there and disconnect everything except one cable from the USB service port to the MS-2. 

The room sounds really good.  The new rack is about 350 pounds net weight (the old one is in a spare bedroom).  I got the rack from Klaus (Odyssey Audio) around the middle of June and by the time I got it together and figured out what was going to fit the way I wanted it and what was not it was 2+ months (it's a bit harder since it is an integrate HT too).  I have not had the time I would have liked to date as I was messing with the multiple systems and they close to done except for minor stuff.

Rich explained to me the MS-2 and the MS-3 sound identical.  The MS-3 as noted by Rich uses the Intel N2600 motherboard (the MS-2 used the now discontinue Intel 2800).  The MS-3 has no high speed USB ports which won't make a difference to me as I have powered Oyen Digital drives and the MS-2 has an extra USB port.

I just got two 4TB Oyen Digital drives for the main system (one of the 3TB ones was getting nearly full).  So now I have almost 3TB of space available for music in the main system.  I have the old 3TB drives which will be going in the room with the MS-3 (basically a back-up but since I'm anal, I have plain old commom drives with another copy and also if I want to attach them to my router at some point to see how that sounds - have Oppo players as well where I can try stuff like that)

This is the old furniture from the main system.  Probably going to get a wider bridge, swap out the 55 inch TV in there with a 50 inch one in another system so it sits lower (better viewing) and use one of the old bridges as a stand for the center channel.

Question - can the dspMusik be built out to do FIR filters and phase correction like a DEQX?  Or is it limited to IIR and simple EQ like the miniDSP and Behringer DCX?
Title: Re: HAL's MS-3 Music Server and dspMusik 6x8 DSP crossover and HiRez DAC's
Post by: HAL on 15 Feb 2015, 08:42 pm
It does not have FIR filters, only IIR since they are not linear phase. 

I have techniques for both impulse response and phase correction to try.  The code is available for convolutional filtering.  I have methods for measurements that are in work. 

Since REW is available and UMM-6 are inexpensive, room work is happening for woodsyi.

More once I am back from travel.

Well, I am already interested in the unit, even as-is with just IIR filtering.  The 24-192 capabilities and better DAC's are a clear improvement over the hardware of the miniDSP 2x10HD I use currently for my bastardized GR Research V2's.  If impulse and phase can be addressed to give perfect response, I would be extremely happy with such a solution.  I was actually looking at the OpenDRC module to snap into my miniDSP as a convolution engine and a program like rePhase or Acourate to do the phase/timing corrections with my 2x10HD unit.

But if the dspMusik can do it all in one box and at a higher resolution rate, that's pretty much ideal for me.

Tyson,
This will be an interactive process, since automation would require other software that I use to process the data.

The idea will be users make measurements and send the data to process.  Correction file will be sent back for use with a new block diagram for use. 

I already have a document I wrote to do the measurements. 

More as I get it changed to work with this hardware and the UMM-6 mic.

Feedback from both dpd and woodsyi have been very positive on the dspMusik digital crossover.

Will be receiving the next batch of dspMusik units next week.  All are already spoken for!

Also building Phil's MS-3 Music Server to ship Monday.  Will follow that with two more MS-3's when the parts arrive.

Have Room EQ Wizard and the Dayton Audio UMM-6 calibrated USB Omni measurement mic to go to woodsyi's for some room measurements.  Will load REW on his MS-3 and install the calibration file for the UMM-6 to setup the PEQ parameters for room EQ on the dspMusik. 

Will be experimenting with my friends MS-1 running REW and downloading the room corrections to his DCX2496 for trials and then install a dspMusik to replace it with the same PEQ room corrections.  Have a USB to RS232 cable for direct connection from MS-1 to DCX2496 for trials.

This should be fun.  :D

Setup one friends MS-1 Music Server to control a dspMusik crossover to run his VMPS RM50 biamped speaker setup. Showed him how to build crossover block diagrams by updating his to the new high resolution filters. Should have his dspMusik to install this week.

Also installed a USB to RS232 cable from the MS-1 to his Behringer DCX2496 and have Room EQ Wizard installed on the MS-1 to use with a Dayton Audio UMM-6 calibrated omni directional measurement mic for room measurements. It calculates PEQ filters for room correction to download to the DCX2496 via the RS232 interface for full automation.

Once that is complete the PEQ filter data can be documented with the Behringer DXC2496 software on the MS-1 and printed to use with the dspMusik setup for PEQ filters.

Very simple to setup and operate if you already have a DCX2496 as he does.

For folks doing recording of two channel analog sources to digital, have been working with the MS-3 and Audacity with an Echo Audio Echo 2 USB2 ADA.

The setup does 24bit/192KHz recording to the SSD on the MS-3 for multiple hours of space.

Have also used Adobe Audition on the MS-3 with the Echo2 with excellent results.

Will be setting up the turntable and DSA Phono One beta unit for LP transcription with the system to add to the library.

Next batches of MS-3's and dspMusik's start arriving tomorrow.

Working with woodsyi to do the room measurements this week to complete the room EQ demo in his setup.  Will have the dspMusik demo unit back after that for the next set of demo's.

Pez and Tyson are next up for dspMusik trials once I have another MS-3 built and setup with the dspMusik.  Balanced TRS to XLR cables are on order for a new set of two input and six output channels. 

Will be setting up the dspMusik with an MS-1 with the VMPS RM50's once the cables arrive for that setup as well.

Will be sending a 1 meter Virtue Audio USB2 cable with each setup as that has been the most reliable cable with the setup.  Ran into issues with some generic USB2 cables not working properly.  Those are on order as well.

The issue is getting measurements of the V2's to use to build the crossover block diagram.

I have to know that information to build something to use with the dspMusik.  I do not have access to a pair of V2's for doing that.

If they are Danny's V2's, he will have the information. 

I have Danny's Super-V's here and they are very different than the V2's.

Do you use room measurements or speaker measurements from 1m of each driver or whole speaker?
Title: Re: HAL's MS-3 Music Server and dspMusik 6x8 DSP crossover and HiRez DAC's
Post by: HAL on 25 Feb 2015, 08:37 pm
For doing the crossover it is a combination of 1 meter far field for the coaxial and near field for the woofers.  Same technique that MLSSA uses for their combined measurements like you see in Stereophile that John Atkinson does. 

The difference is, I need the individual drivers to see how to build the crossover. 

One thing I am trying is using REW and a Dayton Audio UMM-6 mic to do the measurements.  Easy to install and run on a MS-3 and mic runs about $85 from Parts Express.

Taking a setup like that to woodsyi's on Friday to try room measurements, since we already have his crossover done.

Also going to add his back subwoofers to the last two channels on the dspMusik for swarm style use.  Bringing another set of TRS to XLR cables to connect his rear amps.  First setup to use all 8 output channels from the dspMusik.

Actually this DSP board has many installed users from it's original use as a subwoofer crossover.

It has been modified since for full range use. 

My understanding is that it was the crossover used at Sea Cliff in Harry Pearson's sub setup.

This is slick Rich, woodsyi has enough subs so that you can place at least two at the rear of the room by the bed and cancel out the bass wave from the front before it even hits the rear wall and causes a problem with bass standing waves.
I am hoping he will host a BBQ this year after you have optimized his system.

Do you have driver level measurements for your moded V2's?  If so, that would be a good starting point.
Title: Re: HAL's MS-3 Music Server and dspMusik 6x8 DSP crossover and HiRez DAC's
Post by: *Scotty* on 25 Feb 2015, 11:04 pm
If standing waves are currently a problem, when you cancel out the wave from the front before it the rear wall and hopefully reduce their magnitude, there should be a corresponding improvement in the three dimensionality/ immersive surround quality of the recreated acoustic space. It should be dramatic, if the rear subs are turned off, the sound stage should collapse towards the front of the room.
 Also the RT60 numbers should look a lot better below the frequency point where the rear woofers delayed opposite phase output affects the room settling time in the schroeder frequency region. Theoretically one could possibly remove or relocate some of the room treatments dedicated to affecting the bass frequency range.

Got the Monolith 8" full range with 3x8" servo woofers with the Rythmik HX300 amps running yesterday with the dspMusik 6x8 as the digital crossover.

Used lots of techniques to flatten the response.

The OB next to them are the prototypes of the powered desktop speaker using the BG NEO3/NEO10 combination.   Both sound very good, but very different.   Once I have the 3x8" servo H-Frames from Ruben built, will get those setup as well.

Have Room EQ Wizard running on an MS-3 working with the dspMusik and a Dayton Audio UMM-6 calibrated mic for room measurements from the listening position.  The dspMusik is running as both the crossover and measurement output.

Phil,
Yes, that is the one I am using.

Once you have it, go to www.DaytonAudio.com to download the calibration file with the serial number.   After you plug it in and it loads the USB driver, start REW.  REW will ask for the mic calibration file once it sees the UMM-6 is installed.   

The instructions to run REW are online to view.

The UMIK-1 is similar to the Dayton UMM-6.  Both about the same price.

I picked the UMM-6 since REW is setup to work with it directly.  Probably others will work as well.

This has a 1/4" mic capsule in a narrow tube compared to the UMIK-1.  Has similarities in design to the Earthworks M30 series measurement mics.

Just downloaded the HDTT 24bit/192KHz Falla HiRez files to a USB flash drive to have for checkout.

Finished building up an MS-2 with Windows 10 to run the dspMusik for demo's.  This setup is heading to GR-Research for Danny to checkout.  Have a few different block diagrams for him to try with various ideas.

Would be fun to hear how the dspMusik DAC section sounds with the LS-X speakers at his place running from both a PC and MAC.

Post by: HAL on 28 Feb 2015, 05:46 am
Just got home from woodsyi's.  Good to see him and Scottdazzel today for a MS-3 and dspMusik setup session. 

Replaced the original demo unit with one of the latest batch of units.

Listened to the setup before removing the original dspMusik and great sound quality from the digital side with HiRez PCM and DSD files. 

Replaced the dspMusik and added the rear sub channels with single ended connections.  This had all 8 output channels running, two for VMPS RM40 mid-tweeter channels, two for RM40 woofer channels, two for VMPS sub front channels and two for the rear channel subs.  Rear channel subs are at the sides of the seating area in his setup.

We listened to the full sub setup and then made a REW measurement.  Noticed that the area around the 80Hz crossover point had two nulls and high loss to the UMM-6 mic location.  Turned off the subs and filled in one of the nulls, but still one remained at 80Hz.   Since the rear sub channels are closer than the front subs to the seating area, need to work on time delay for the rears to integrate correctly.  Until then the subs are off for a future measurement session with a longer USB cable from the MS-3 to the UMM-6 mic. 

woodsyi is putting some hours on the new unit to see if there is any change in sound quality.  The original unit had many weeks of time on, where this one was new from the packing.   I am going to compare my demo unit here to a new unit to see if there are any sound quality differences. 

Next, will be installing a dspMusik with the VMPS RM50's with the MS-1 installed next and then a system goes to Pez and Tyson, once I have another MS-3 built.

Great picture!

At Avoosl's place now.  Just installed the dspMusik in his setup with his MS-1 for the VMPS RM50's.  Figured out that the latest version of the firmware uses the wrong DAC filter and know how to fix woodsyi's setup.   Will talk to him soon.

The VMPS RM50's with the dspMusik sound excellent running the filters that Bryan recommended for the DCX2496.  This just sounds a lot better.

System #3 is sounding excellent as well.

Have now tried the new filter selection software and the minimum phase apodising filter selection is my favorite for sound quality.

Have updated 3 systems so far with woodsyi to go to use that filter.  From now on that filter will be the default selection for all the dspMusik units going out.

Very easy to change if the user wants to try the other filter selections.

The MS-2 running Windows Technical Preview just updated itself to the Pro version as one of the updates.  This should be interesting.  Everything is still running correctly.  This one will go out for demo as soon as the next batch of dspMusik's arrive.

Hi Rich,
Just curious if it is possible to upgrade my MS-1 with the MS-3 mother board. It probably is not possible, but I do like the idea of not needing a fan. Does the MS-3 sound as good as the 1, and does windows 8 have any advantages in sound quality over 7 ? My MS-4 still sounds great, and looks good too.
Thanks

The chassis for the MS-1 and MS-3 are very different.  That is why the MS-3 can be fanless.

Windows 8.1 sounds better to me than Windows 7.  Windows 10 will be out this year and from the demo version it sounds like Windows 8.1.  There will also be a free upgrade from Windows 7 and Windows 8.1 to Windows 10 good for 1 year after release.   It maybe a good idea to upgrade the MS-1 to Win10 since it will be free.  I have not tried it, as I have no MS-1 chassis here to experiment with.  Win10 is working very well on the MS-2 and MS-3 chassis at this time.

There was a series of articles in The Absolute Sound that compared OSX and Windows 7 for sound quality on MAC hardware.  I will let everyone read it to see which they preferred.  :)

That's good to hear about the free upgrade as I have an MS-2, MS-3 and my main PC is Windows 7 Professional.  I'm fairly careful with PCs.  I got rid of a Windows 98 Machine about 18 months back that still worked for the most part and still have an XP machine (and if the OS was still supported it would be connected to the internet as it has 3G of RAM and still works great).  And I also have an old Mac G5 Tower that I bought used.  I have the XP and Mac in the bedroom and use the Mac to surf the web.

Contacted the Danville Signal Processing folks yesterday and they are sending the latest 1.0.0.6 firmware to me to update the dspMusik demo unit.  This way everyone hears the same thing as the production units.  Only difference is the demo unit does not have the connector for the S/PDIF input like the production chassis. 

The chassis for building two MS-3's arrive Friday.  Will get them setup and will send one out with the dspMusik to Pez and Tyson. 

The MS-3 will also have Room EQ Wizard installed and a Dayton Audio UMM-6 calibrated USB mic to do room measurements at the listening position. It has a small mic stand in the case to sit it on a flat surface.  A mic stand with a boom is a good thing to have access to in some cases.

I do not install the Windows Pro version on anything, this was something Microsoft did as part of the Windows 10 demo version. 

I have not tried Windows 8.1 Home or Windows 10 on the MS-1, so I do not know.   It is a simple experiment, but I do not have any MS-1's here to check.  I have a blank SSD drive to install to load a fresh copy of Win10.  It can be done without modifying the existing SSD boot drive for Wndows 7.

If you would like me to check your MS-1, I can with Windows 10 until April 15.

Rich,
Thanks for the offer. My MS-1 is still sounding great, so I am not going to do anything to it for now. But if you do find out that the MS-1 does work with win10, and sounds at least as good as it does with 7, let us MS-1 owners know so we can update when it becomes available.
Thanks Rich,

I think the MS-3 and dspMusik ate woodsyi!  It's been very quiet.  Hopefully that means lots of listening! :D

I am quiet because I am listening seriously -- between snow shoveling sessions.  Changing back the filter from brickwall to linear phase is a must for me.  I couldn't stand some voices with the brickwall.  I am still fiddling with the level matching and need to phase in the rear subs before I can completely say I am sold without reservation.  Since I have been listening to MS-3/dspMusik for a few weeks now, I am going to plug back in the analog crossover this weekend and compare.  I have a feeling I am not going to like the bass response on the analog x-over but I want to compare the treble/mid tonality.  I have been hearing a lot more bass resolution with symphonies. 

I will let you know.

P.S.  If it wasn't good enough, I wouldn't even be listening right now.  If I only had digital frontend, I would be all over it already.  I am getting better digital out of dspMusik than my current DAC that costs 10x more.  I have to be convinced that vinyl doesn't suffer.

Had a fine listening session at Avoosl's last evening with the HAL MS-1 and dspMusik crossover running the VMPS RM50 speakers. 

Ran his Oppo BDP-105 as the source into his preamp into the dspMusik and did a great job with that source.

He is now the first official owner of the dspMusik system.  Soon to be followed by dpd as the second owner of a dspMusik.

Today is working on finishing the desktop speaker system 3x8" servo woofer system OB H-Frames.  Wiring them up to the Rythmik HX300 servo amps once I have wire and more Speakon connectors.

Pez received the MS-3 and dspMusik yesterday.  We will be talking as soon as he has time for setup.

Will be at woodsyi's on Wednesday evening for room correction trials with the dspMusik trying out SWARM techniques.  From what I read, this will require time delays and shelving filters to account for the sub positions and room gain in any room.  These can be added to the block diagram easily on the sub channels for listening trials. 

Will use REW with the UMM-6 mic with a max length USB2 cable to make before and after measurements.  The dspMusik will act as the signal source for the measurements with the MS-3 running REW.

Just got home after the latest session at woodsyi's with the MS-3 and dspMusik.  We reconfigured it as the total bass management system for his main RM40 woofers, front subs and rear subs.  Added digital crossovers for the three pairs of woofers and delay for the rear subs.   No more drop in response.  Still need to send him a UMM-6 calibrated mic for more REW measurements.

He is now the third owner of a dspMusik.  He has a CAPS2 Music Server, so will get the MS-3 back after he is happy with the final setup and burn the firmware. 

Now to see how Pez is doing with his demo setup.

For woodsyi's setup last night did some updates to his CAPS2 Music Server Foobar2000 install.  He wanted to get it running with his EMM Labs DAC2X.  Installed the correct components and fixed the settings to work with his DAC2X and DSD files. 

Also put Foobar2000 into memory playback mode so that the entire music file is loaded into memory before playback.  No more dropouts like he was having.  He is doing some long term testing with big music files to see if the updates work and the dropouts are gone all the time.

Post by: woodsyi on 12 Mar 2015, 03:35 pm
Rich has been a trooper driving 2 hours each way 3 times in a few weeks to set up the dspMusic in my room.   After I heard his prototype at RMAF last year, I put myself in for testing his dspMusik.  We set up first where I replaced the Marchand analog crossover with his dspMusic.  The digital direct was a revelation in what digital processing can do in it's domain.  Taking the analog preamp and analog signal processing out of the loop, everything was processed in the digital domain before the excellent DACs outputted analog signal to the amps.  I could have lived with it just fine if I didn't have a stable of turntables and 5k plus records.  Some of my beloved opera and classical music do not exist in the digital domain.  When the analog front end is introduced via the phonostage and preamp into dspMusik through it's ADC loop I lost some clarity and the tonal liquidity that makes vinyl so magical.  It wasn't much of a drop off, but the veiling was there and my Koetsu wasn't delivering it's mid-range magic (bloom).  I put the analog x-over back in and the seduction came back to female vocals but clearly there was a drop off in the bass precision. 

The compromise Rich and I arrived at is to retain the mid/high to analog processing and use the dspMusik to processing just the bass (from 280Hz down).  I have 4 10" woofers on the VMPS RM40s, 2 12" and 2 15" ona pair of VMPS Larger Subwoofers, and 2 18" woofers on a pair of sealed box subwoofers custom made by Kevin Haskins from erstwhile DIY Cable.  I wonder what happened to him.  All dedicated to producing music 280 Hz down driven by 5 amps -- a pair of Acoustic Reality 1001s, a Crown K2 and 2 Dayton SA1000s.  My room has been extensively treated for bass damping.  We are matching the low-pass on the RM40 woofers with the Marchand high-pass of the ribbons at 280Hz using Linkwitz-Riley 4th order filter.  Once a first order high-pass chip arrives from Marchand,  we can match the low pass on dspMusik to try that set up.  The 10" woofers are high-passed at 80Hz and the subs take over from there with low-pass set up at 80Hz.  We put in a volume control on the eAR 1001s as I don't have any volume control on those amps.  K2 and SA1000s have volume control.  SA 1000s also have phase control.  The "rear" subs are actually beside the listening position and there is no room to place them further back.  Rich measured the distance from the front subwoofers to the listening position and put in a delay so that the "rear" subs could act as if they were further back in the room.  The phase was reversed using the control on at the amp. 

With everything put together, we fired up the amps and listened.  We had to adjust the eAR amps up.  You could tell the lower mid-range lacked punch.  Once we adjusted it by ear, we were good to go.  Since we are not using digital direct through dspMusic, we had had to get my digital front end (PC audio with EMM DAC2x) integrated.  We couldn't get a EMM driver to install on MS-3.  So we went back to my music PC which uses the SOtM USB card that is powered by it's own battery PS.  I use J-River and I have always had some drop out issue with big files with play from memory setting.  So I wanted to try foobar and see if it did better.  I used to run foobar with my Empirical Audio stuff but I had a tough time setting up the whole thing to run DSD or even PCM.  Learning curve was too high for me and I did have J-River that was working, albeit with a little hiccups.  Rich took over and breezed through the set up to play PCM.  He had to look up and download a few things and toggle some switches and he had the DSD direct running all within 30 minutes total.  Then we heard a dropout.  I had told him that I wanted seamless play between tracks as a lot of the classical music is continuous and track dividing is really arbitrary.  That seems to be the issue as buffer setting need to be low to play seamless and the DFF files are big.  So we set the buffer way up and no dropout occurred.  It was just one track but I am optimistic that I have finally "licked" the problem.  BTW, the track (a DFF file of Organ playing Bach's Toccata and Fugue in D minor, BWV 565) never sounded better.  I could discern the primary notes in the second octave and even the B0 at 30Hz was clear.  I can't wait to completely dial in the FR and listen to some deep bass.

After Rich left, I played Norah Jones' Blue Note issue Come Away with Me on vinyl and then on DFF playing DSD direct.  The vinyl has got its grooves back.  I am happy.

woodsyi,
Thanks for the words of encouragement!

Glad that the hybrid system is working for all sources with great sound quality.  The system flexibility is high and it takes time to find the correct setup to do everything.  The Bach Tocatta and Fugue in Dm really did sound very good before I left! 

It will be interesting to hear what happens with Pez's setup now that he has the dspMusik to run 3 way with his RM40's. 

The rear subs are running with 10.6mSec of delay for the 12' offset. 

Danny also now has a MS-2 and dspMusik setup for trials.  That will be interesting as well.

Have fun listening!   :D

One option that is now available is having an internal 1TB SSD drive for boot and music storage.  This can be added to MS-3's as well as an upgrade.  They are 7+ times more reliable than a standard hard drive and silent.

The cost for an MS-3 configured originally with a 1TB SSD is $1299.00, the upgrade for an existing MS-2 or MS-3 is $500 + shipping.

This still gives the internal DVD option for ripping CD's to the music library.

This should be an option for medium size CD and HiRez music collections. 

I still recommend an external hard drive to backup the files.

The turntable setup is being run through the 24bit/192KHz A/D converter. 

The demo also includes comparison to his existing Music Server as a possible replacement.

The person demoing the unit also does recording and mixing and uses this system as a home studio and for listening purposes.

Post by: dpd on 18 Mar 2015, 12:37 am
Onto the (very long) comments:

I replaced a fully-modified Behringer DCS2496 (every mod available) with the dspMusik.  I've had the DCX in my system for about a year and was pretty happy with it:  fully configurable both as a crossover and to enable some room correction.  The settings: a 4th order LR at 86 Hz with a PEQ in the subs to fix a narrow band resonance and a PEQ in the mains to fix a broadband mid-bass/lower-mid resonance.  Those modes were based on very simple averaged noise measurements I made with an NTI Acoustilizer meter.

Before I put the subs back in the system, I drove my digital sources through a Benchmark DAC-1.  A reasonably-priced, awesome sounding device, in my opinion.  If I only had a multiple-channel version of one of those to put behind a purely digital in/digital out crossover, that would be it.  (Actually, it was at a dinner with Rich when I told him this, he looked up, gave me one of those 'Rich looks' and told me 'already got it, just wait a bit'  The wait has been worth it, big time!)

Rich cloned my DCX settings exactly, but cut out all of the unused Behringer processing blocks.  I got both units installed and loaded up the dspMusik.  Rich talked me through everything.  No problems, easy...   :thumb:

Since nearly all my listening comes from SPDIF sources, I started there.  No USB or analog connected.  1st time I ran up the volume I noticed a very significant amount of hiss from my music server (not there with the DCX).  So, I tried the CD and ProTools and the hiss was either gone or dramatically reduced.  I have pretty long SPDIF cables (all Apogee Wyde-Eye) so Rich and I guessed it could be cable length.  I bypassed my SPDIF selector switch and that seemed to help.

(My music server runs JRiver MC20 and all my FLAC files are 44.1/16)   I just started out with a playlist I use when I make system changes.  What I heard in a nutshell:  an improved ability to follow reverb tails, great control over dynamics, complex waveforms don't seem to bother this, great headroom.  The bass seems better but I thought it was too low overall.

And that's when I made my 1st mistake:  I decided to adjust the bass volume in real time using AudioWeaver.  I didn't realize the adjustment range on these controls defaulted to +/-100 dB!  I tried to type in a 1 dB increase but I didn't get that quite right and increased the volume by some number that probably can't be typed without the use of logarithms.  To make matters worse, I was tweaking the Left Main, not the Left Sub.  That's when I thought I destroyed one N2X.  After I calmed down, I went back and adjusted all volume sliders for a -10 to 0 dB range.  whew....

Moral of the story - if you want to tweak things, DON'T DO IT IN REAL TIME WITH LIVE SIGNALS.

I also listened to some of my (amateur) recordings: solo classical piano, straight jazz, fusion, simple acoustic stuff, Motown/R&B.  Everything just sounded better as noted above.

So, I'm pretty much happy, no?  And then Rich unleashes the Apodizing DAC filters on me... OMG!!!

A new dsp load and the sonics are just more of what I heard to start.  Reverb tails/delays - one of the hallmarks of the nCore's - I'm now able to actually detect the onset of a delay and hear the repeats in the recordings.  They tails just extended even more - you can follow them well after the next transient comes in.  Bass - solidified on the extreme low end.  It's the same sense as when you move a low frequency corner down another octave.  Impressive!  Percussion:  the edges are just so well etched in time it's uncanny.  Imaging is still there.

Sunday was on to the analog input.  I don't sense the A/D getting in the way, at all.  Been cycling through a lot of different recordings and I don't sense any significant loss but I haven't yet played the SP-9 output directly into the nCores (I'd lose the bass that way).

An astute reviewer would swap back and forth.  Unfortunately (fortunately?) I see no reason to go back.  I'm sold - the dspMusik is hands-down the better device.  there are user-interface things that need to be addressed, but the sonics so far out-weigh the convenience of the alternative, it's not that big of an issue.

Conclusion - the dspMusik is a major league audio device that still has room to grow.   Likely not much sonically, but certainly from an end-user perspective.  Given that I have the same amount of $$$ invested in this as I have in the fully-modded DCX, that's a clear win in the value camp.

Sorry for the long-winded post....

Very interesting.  Will have to try comparing it to the iFi IUSB power to see if there is any gain in performance.  The iFi unit arrived and getting ready for some listening.

A new MS-3 is ready to ship tomorrow to it's new owner Ernie. 

The modular line array speaker driver test samples arrive today or tomorrow.  These are all planar magnetic drivers for the OB line array to go with the scalable servo sub array Ruben has built flat packs for and shipped.  The Class AB amp test modules are built to use with each driver.  They are being tested with the OB desktop speaker system.  Using a few different amp modules to see which has the sound qualities I like with the drivers.

Leaving next Tuesday for Texas to try some of these ideas at GR-Research with the MS-2 and dspMusik already in place.

To be complete, it is 1/3 of the Modular Open Baffle Line array concept in work.

The other 2/3 is a 7' Open Baffle line array with planar magnetic drives for midrange and tweeter.   Dipole radiation pattern.

Have sample planar drivers here to test.  There maybe other drivers to test along the way before the decision is made.

Taking a slight right hand turn, have two different amp modules in work for trials with the OB line array drivers.

Both are ChipAmp style units with the correct power for each driver.  They are being modified to use balanced inputs instead of single ended.  This is to allow an amp per speaker driver.

Report from CO that the setup running the Sanders 10D speakers is doing well.  Just went over the user settings for bass channel levels so that different amps with different gains can be used.

Using REW with the UMM-6 mic is a very good option for this type of measurement.  Run REW with a 300Hz bandwidth measurement and you can see the woofer to panel integration levels.

Wow, what a day.  I've heard some pretty amazing stuff at the various RMAFs that I've gone to, but nothing like what I heard at Danny's yesterday.  I'll wait to be specific until I know when and what Danny, Rich, and Gary want to release for public consumption, but it's simple to say that this was THE best audio experience I've ever heard.   :o
I know that that kind of hyperbole gets bandied about too often, but this system just truly was absolutely amazing.  Throughout the day, I kept listening for passages where my LS9's would have kept up.  I think there were a couple of times when I thought my system was about as good on a particular passage.  Just for a minute. Maybe not that long.
Most of all, it was also wonderful to see Gary up and active.

Tyson,
The OBLS were in use today with the dspMusik like your demos using Danny's MAC mini so he could use his demo tracks. 

My listening impressions are that these are the successors to the LS-X speakers that are in the back of his listening room.  These are better in many areas, and improved in some areas with the dspMusik since I could electronically time along the servo woofer array to the main baffle for improved integration in sound quality.

I would suggest that anyone interested in a demo contact GR-Research soon before they go to the owner with the passive crossovers.  I have removed the MS-2 and dspMusik from the system to go to the next person in line for a demo. 

Danny does have pictures from today for a thread on the OBLS and his observations.

Getting ready to test two of the ChipAmp style Class AB amps with the planar drivers to see what I can get out of them. 

Will start with the desktop OB speaker and get the two 3x12" modular OB servo subs built.  Will be using the dspMusik digital crossover for direct drive to all the amp modules directly to the drivers.

Nhan has the MS-2 and dspMusik setup running as a DAC in his system for listening. 

Sandbagger will be getting the MS-3 and dspMusik setup this week. 

The final driver samples arrive this week for testing with the modular line array concept.  Should have the 12" OB servo sub cabinets ready by the time they arrive.  Building a simple baffle for this one to compare to the desktop OB array with the BG NEO3/NEO10 drivers.

Today is the MS Windows Technical Preview expiration date.  Just had to roll back from the Pro version to the Standard. 

Hopefully the full launch will be this summer and can do the free upgrades from Windows 7 and Windows 8.1. 

I will get a copy of Windows 8.1 Pro 64bit for trials since it has Remote Desktop and that worked on the MS-3 platform.

A few more oak pieces to cut and can start building the test baffle.

Starting the packing process for Axpona next week.  The MS-3 and dspMusik made it to it's next demo and then comes to Chicago.   Have one request for a demo, so we shall see what happens.

The MS-2 and dspMusik in TX are doing well with a pair of LS-6 speakers.  Looking forward to more listening observations once the demo is complete.  Then it comes back to the Lab.

I have an LS-9 crossover to measure from Danny for doing a dspMusik version.  Will look at the LS-6 as well once I get the LS-9 version completed.  This would allow biamping the two speakers after the internal crossover is removed and extra connectors attached to the driver leads, like the Electra Tube Connectors. 

Hope to see folks in Chicago coming up!

All the sub modules have been moved to the audio room. 

Talked to Danny and will use the production HX300 amps with the two 3x12" servo sub arrays until I get the rest of the 12" drivers and the HX800 amps.  These have the shelving filters, so should be fine. 

Will finish the 6-12" driver install and wiring tomorrow and setup using the dspMusik crossover to the NEO3/NEO10 OB desktop speakers.

" It doesnt suck" is a bit of an understatement.

I wished I didnt have to pack it all up and take it to Chicago for Axpona but I do.

As a DAC it was very very clean. with all the HiRez and DSD files I had time to play I was hearing things I had never caught before.

 Wished I had time to play with the Xover part of it as the ML or LS6's would have been a lot of fun.

Reading the evils of crossover thread is interesting.

With help, I put together a Dayton Audio 8" full range driver in a U frame, with 3x8" servo subs.  Listening to the system without any correction for the full range driver was pretty bad.  Using the MS-3 and dspMusik crossover, I did simple corrections to flatten the response of the full range, and measure to integrate it with the servo subs. 

If anyone tells me it sounds better before the crossover, I would show the them difference.  Not even close, and sounds much better corrected.

Made it home from Chicago!

Both dspMusik demo systems have arrived back from travels.  One unit is slated for trials with a pair of Sanders 10C electrostatic hybrid speakers once the owner is ready.  The demo with the Sanders 10D speakers went very well.

Upgraded the MS-3 to Windows 8.1 Pro and doing the latest MS updates now.  Once completed, will be trying Remote Desktop with the MS Surface.  Will verify that both Foorbar2000 and Audio Weaver can be run remotely and allow the user to place the setup close to the music system for use. 

There is now an experiment into a new A/D conversion system to use with analog equipment.  Parts were shipped today to begin the prototyping.  This will be a long term design and test, so no fixed time for when it will begin.  Two different methods will be tried for the A/D conversion and the better sounding system will be put into development. 

The fun continues!

Two of the demo systems have returned and the last MS-3 demo unit is on the way back.

The Meridian Explorer 2 MQA DAC will be here today.  Have the iFi iUSB Power setup to use with it for clean power from the MS-3 running Windows 8.1 Pro. 

From the description, it uses an Apodising filter system running in DSP as part of the processing.  This comes from the same research that was used to design the Wolfson Micro WM8741/WM8742 series DAC's.  The WM8742 DAC's are used in the dspMusik 6x8 crossover.   They do not discuss the filtering used. The WM8741 series offers user selectable filters.  All the dspMusik crossover demo's have been with the Minimum Phase Apodising filters after that was added to the Audio Weaver development system.

The Meridian Explorer 2 DAC arrived and the USB driver is loaded. 

Using it with Etymotic Research ER-4S in-ear phones for trials.  Levels are low, even with the volume at max.  Will need to try this with my Audio Alchemy HPA-1.0 for more gain.  Works with Foobar2000 1.3.8. 

Loaded up the Pono Player software and that works.

Looking for some MQA FLAC recordings of interest to try.

The Meridian Explorer2 MQA DAC volume control is buried in the control panel once you find the second page.  Volume level is fine now after boosting is 26dB.

The top three LED's give you sample rate feedback.  The color tells you if it is a standard, MQA or MQA Studio quality file. 

Trying it without the iFi iUSB Power.  Will add the iUSB Power after listening trials.

Very happy with the Meridian Explorer2 MQA DAC running with Foobar2000 for music playback.  HiRez sounds very good indeed. 

For someone looking for a good starting Music Server and DAC, the MS-3 setup with the Meridian Explorer2 is a great intro system for HiRez digital music playback.  The line level output from the DAC is the industry standard 2VAC, so should work well in most systems.

Looking forward to trying some MQA FLAC files for replay once they are available.

Have test data back from Danny on the planar magnetic drivers for the line array idea.  Have sent them to the companies to see if they can build modified versions of the drivers to use in this application. 

Building ChipAmp boards to test out with the drivers.  Have both the LM1875 and LM3875 versions to try for sound quality to power each driver directly.  Have them built with differential inputs and the next set will use so very good resistors for the feedback networks. 

Wiring up the servo sub modules to use with the OB desktop speaker idea for trials.  Will be trying 2x12" servo subs as a stand for the OB planar magnetic two way speaker.

The modified planar magnetic panel drivers are in work.  They are trying to match the parameters I am interested in and waiting on the results.  If they can match the target response, sensitivity and matching, will get 20 samples to build the line array.

Waiting on latest word on the open baffle build from the wood worker.  Spacing for the planar midrange in work is setup for this pair.

Will be back to the sub build next week after some travel.  The clamps fit and need to start wiring the connectors to the 1x12" modules.  Will setup two 2x12" modules to go with the NEO3/NEO10 OB speaker as a test with the dspMusik doing the crossover and time alignment. 

Going to work with REW to see if it can do the time offset measurements needed with the log sweep.  If not, will use CLIO. 

Waiting on word for a demo with a pair of Sanders 10C speakers.  Will be interesting to hear the results as compared to the Sanders 10D demo.

Also waiting to hear word of a demo with a pair of VMPS RM-V60 speakers that had it's original DCX2496 die with the settings. 

Anyone interested in trying an MS-3 and dspMusik setup, the demo unit is available.  Please PM me for details.

The dspMusik 6x8 can now be offered as a stand alone digital crossover that loads the custom code on power-up.  Will take USB input from either a PC running the USB ASIO driver for the system, or from a MAC using it's ASIO driver.  The stereo analog, S/PDIF and USB input connections will be available to the used.

If you are purchasing an MS-3 to use with a dspMusik, I will preinstall the development system to use for parameter changes if that is wanted, or just setup the dspMusik to be stand alone depending on the customers request.

Another pair of 12" servo subs is on order from Danny.  Will be finishing up this setup once they arrive. 

Will be using the Rythmik HX300 servo amps with the subs in the 1x12" modules.  They have the balanced inputs to use with the digital crossover to run these as fully active three way speakers.  Using ChipAmps modified for balanced inputs for the BG NEO3 and NEO10 drivers.

To compensate for the distance offset between the NEO OB and servo subs, will be using pure time delay on the planar array for time alignment.

There is no separate dspMusik 4 channel version.  You program the number of channels needed for the crossover and possibly subs.  Price is $1500 for the dspMusik. 

Every channel can have polarity inversion if needed.  The outputs are balanced, so that is one way, or adding processing for inversion is available.

I would like to do that but do not want to do it if it will not work well on the MS-1, or not sound as good as windows 7 sounds. I doubt if I could go back to 7 again if 10 does not perform as well. What are your thoughts?

 Also, I wanted to pass along my experience with a free upgrade from Fidelizer. It is a program that reconfigures the computer so that more of the processor is more dedicated to music reproduction. I was not really expecting much since I do not have much else on the MS-1 to use up processing power, but I was really surprised. From the very first notes I heard a definite improvement in sound quality. And the changes Fidelizer makes to your computer are not permanent. Each time you shut down the computer and reboot, it goes back to normal. You have to tell Fidelizer to reconfigure again. Definitely worth a try.

Take care Rich
Mark

Mark,
Doing much better!

I do not have an MS-1 anymore to test as my last one went to a band for recordings, but Windows 10 preview has worked well on both the MS-2 and MS-3 chassis with Atom processors.  I know that Chris has two MS-1's and is thinking about the same thing.  You two should collaborate on it.  The free upgrade is good for 1 year after release hopefully in July.

The good thing is that I can always use the original Windows 7 install CD and driver CD to rebuild the SSD for you.  I really like the sound quality of Windows 8.1 and Windows 10 on the newer machines. 

Glad you are enjoying Fidelizer.  I know a lot of people are using it on their Music Servers.  One day will give it a good trial.

Thanks Rich, and  glad you are doing better. Based on your experience with windows  8 and the new 10, I will probably just go ahead and do the upgrade. Glad MS is allowing for free upgrades now! Hope Fidelizer works with 10 too. Once I get it done, I will let you know how it works.

Official release date for Windows 10 is July 29, 2015.

Will be building an MS-3 with the latest Windows 10 Insider Preview today.  This should include the new Edge web browser.  Once the full release has happened, will switch to that one for further testing.

Rebuilding woodsyi's CAPS2 style Music Server as it was having problems with new program installs.  Files started disappearing, usually an indicator of drive problems.

New SSD drive installed and Windows 7 Ultimate OS and upgrades are being installed.

Will be installing the software to control his dspMusik digital crossover and the normal MS-3 software load so he can use his own DAC as well.

woodsyi's CAPS2 PC is now loaded as an MS-3 Music Server for running a dspMusik crossover and measuring with REW.

The 24 hour run-in check was fine and ready to pack up and take to him to swap for my MS-3. 

Have decided to try a two way OB line source using 10 planar magnetic midranges and the 6x12" servo array's per side.  Estimates for the drivers are in and putting together the funds to purchase. 

Since this is a single driver style OB line array speaker, going to try using impulse response correction techniques to flatten the planar response and then crossing over to the servo subs.  Each planar driver will have it's own amp in the line array to give full driver damping and give higher sensitivity. 

Looking forward to giving this a try.

Did room measurements with REW to make changes to the subwoofer crossover points to smooth out the in room response at the listening location.

Yep,  I listened to a bunch of stuff to see how the new setting does and it was 1 AM before I knew it.  It's good with a variety of music.  I think I can finally put the DSP box in it's rightful place and do some tidying up with cables and what not.  Now I can get on with setting up  a new TT in place.  The Oracle TT and SS Strain Gauge are going in for update/repair.

I am looking at this for customers that have MS-1's with Windows 7 OS installed and all the Music Server software working.  From what I see, the upgrade did not work with the previously installed programs.  Since I installed all the software and settings, it would mean a return of the unit for OS upgrade and all the software.

Trying Windows 8.1 to Windows 10 upgrade now keeping all the original programs and settings.  Will look at the install tomorrow to see how it went.

Post by: HAL on 30 Jul 2015, 02:30 pm
The Windows 8.1 to Windows 10 upgrade using a DVD made from the Windows10 ISO file and verified, worked correctly.  All the MS-3 installed programs are working.

I have not done an exhaustive test of the MS-3 system due to time, but so far things are working.  It does appear to run a bit slower than Windows 8.1, but you get the new UI.

Now for the bad news.  If something goes wrong with the Windows 10 64bit upgrade, and the MS-2 or MS-3 needs to be rebuilt, the customer will have to pay for the service and shipping both ways.  The good news is that with both the Windows Technical Preview upgrade and Windows 10 upgrade versions, they both worked correctly after the process on the MS-3 hardware.  I do not have an MS-2 chassis here to test Windows 10 upgrade, but the WTP upgrade did work correctly when I did.

Windows 7 is a totally different story.  The Windows 10 upgrade keeping the original programs did not work.  Will need a total OS rebuild for MS-1's that want to try Windows 10.  The customer would have to pay for the upgrade service and shipping both ways.

Rich, are you saying that the upgrade from 7 to 10 caused the programs to not work correctly, or did they just not load at all. either way, that is not good. why would they do an upgrade if it was not ready.
thanks,

Mark,
I tried the Windows 10 upgrade version that kept all the original programs and files from Windows 7 and for the MS-2 prototype did not go well at all.  It did work correctly for a Windows 8.1 upgrade.  Everything ran as installed under Windows 8.1 in 10. 

I just tried an upgrade that started without keeping any programs and files from Windows 7 and it worked correctly so far.  Reinstalling the programs and files now.  They also have a version that just keeps the user files and not programs.  That would most likely work, but all the programs would need to be reinstalled and setup.

If I could predict anything that Microsoft will do, I might make some money in the stock market!

Best I have come up with in having the full version of Windows 10 for one day.

Rich

thanks Rich. reloading all programs on a desktop would be a pain, but on my MS-1 it would not be a big deal. Mainly just EAC and Foobar, with maybe two others. Let us know what you think about the sound quality o 10 compared to 7 and 8.

Windows 8.1 and Windows 10 sound better to me than Windows 7.  The audio path was changed after Windows 7. 

No way to test the MS-1 here with Windows 10 as I do not have one anymore.  As long as you have all the discs I sent with the unit, should be good to go.

Backup the full Download sub directory and you should have all the programs to reinstall after the upgrade.

I agree that it is tough to get anything but a general idea from the show about audio components and speakers.  I believe the woofers in the GT speakers just roll off with no crossover but perhaps Greg can clarify.

I agree that it is tough to get anything but a general idea from the show about audio components and speakers.  I believe the woofers in the GT speakers just roll off with no crossover but perhaps Greg can clarify.
The planar panel operates full range and has no xover...it naturally rolls off on both ends.
The woofers use an internal amp with an adjustable electronic xover 18db/oct.  that was set around 100hz.
The ribbon tweeter uses a single cap for a 6db/oct rolloff below 3k

Rich's HAL unit has an available xover to integrate additional subs in time and phase to clean up room nodes.

Guy's,
During the video, the MS-3 and dspMusik were not being used since he had a demo CD.  That was the moded JVC player.  That setup did sound very good.

After the video, I played the HiRez recordings with the MS-3/dspMusik and that did not make the video.

Everyone that heard both the moded JVC player and the MS-3/dspMusik setup thought it sounded even better!

Just trying to make sure things are given the correct due from the video.

The song playing when the video opens is from The CD Strike a deep cord, its Dr John and Odetta doing Buddy can you spare a dime.
The other instrumental tracks were from the Audiophile CD "Chasing the Dragon" available from elusive disc.
Peter Brueninger from AV showrooms brought it for the video.

Unfortunately Rich's great server and dac did not make the video.
The CD player used in the video is an old tank, a JVC 1050 heavily modded by Terence Robinson of Paradox Pulse.
My personal unit.
Its ancient but sounds great even today, but time marches on and Rich's server/dac brought it up notch for less money and ease of use that cant be beat.

Phil, What clinched my decision to order a pair of GTA 2.5s were the RR HRX cuts Rich played using his MS-3 and the dspMusik DAC, absolutely stunning! The DAC was used only as a DAC (no DSP), and although I couldn't do an A/B with the Paradox modded JVC, I thought music played from the server was excellent. Once I get my GTA 2.5s, I'll have a DAC shootout with NuPrime DAC-10, dspMusik, and AQUA LaVoce. After I recover from the speaker purchase, the MS-3 will be next.

Kemp - you'll love the MS-3.  I have the MS-2 (identical sound slightly faster processor - the mother board was discontued by Intel, although I sent Rich a PM about a generic replacement) and the MS-3 (the music servers are in separate systems) and I find it is a great simple and user friendly interface with something like JRiver.  To the main system, following Rich's posts elsewhere, I bought an iFi USB Power Supply between the music server and DAC which was a really nice improvement.  The power supply is not workable in the secondary system (with the  MS-3) as the USB chip in the DAC carries the power.  Sometime over the next few months I'll get around to doing Windows 10.  I find with great source material, it really makes the system shine.  I just got Stxy's 'Paradise Theater' on an SHM SACD from Japan today and will burn and extract the DSD file before the weekend is up.

Just got off the phone with one of my dspMusik customers that was originally running a heavily modified Behringer DCX2496 with his setup.   He is still very happy with the dspMusik in the system being used for both music playback and recording mixing with ProTools in his setup for the monitoring system. 

He built an FM radio station in Indiana and wired it with 1 mile of balanced cables for the control room, booths and recording rooms.  This is typical of most studios for recording the music and monitor playback for them that we listen to in our systems.   He is doing the same at home with the dspMusik for balanced output, but single ended input from his analog gear.   

We discussed reworking his monitor speakers to run them biamp from the dspMusik with another pair of NCore amps like the ones he is using now.  The speakers are GR-Research N2X with separate TL subs.  We also discussed possible OB H-Frame subs to replace the TL subs he has used for years.   Since I have a pair of N2X, making the measurements needed will be easy to do. 

The dspMusik can be run either balanced or unbalanced with adaptors from the TRS connectors to existing cables.  It has worked very well for the systems running them today.  Have used the dspMusik with Mogami, Monoprice and Hosa balanced TRS to XLR cables with excellent results including my system with the Mogami cables.  Also have used it with TRS to dual RCA adaptors with many RCA cables with great results. 

Have also made custom TRS to mini-XLR cables to use with the Rythmik HX300 amps for the 3x8" OB servo subs.  Many options for connections to systems exist.

After a lot of travel, updated the MS-2 Music Server with Windows 10 and listening tests are going well with the dspMusik as the DAC, iFi iCan and HiFiMan HE500 phones.  Have already run Windows 10 on MS-3's with fine results.


After reading the Meridian MQA info that I can find, there are interesting parallels in how the dspMusik works and their processing.

Working with Danville Signal on the next generation AD for the dspMusik.  The prototype in work is a 32bit/768KHz ADC with minimum phase filtering to complement the minimum phase DACs.  There maybe another surprise to go with this, but that has to wait for how things work.

Hope everyone has a Happy Holiday Season!

The three way open baffle speaker is up and running.

The setup is the GR-Research BG NEO3PDR tweeter, BG NEO10 midrange and 2x12" H-Frame servo subs running with a Rythmik HX300 servo amp.  More tweaking to do, but these sound very good! 

Too bad Christy Digital cannot produce the NEO drivers any longer as these are really great sounding speakers.

I will never go back to passive crossovers again after working with the dspMusik digital crossover and amps directly driving the speakers! 

Will make some measurements after getting all the levels fully adjusted.  Using Room EQ Wizard with the Dayton Audio UMM-6 calibrated mic from the MS-3 directly through the dspMusik to the speakers.

Yep  :thumb:

The PCM files sound fantastic!  Unfortunately I still haven't figured out how to play the iso and dsd files without buffering issues.  The JRiver forum thinks it's a computer/processor issue.  They have a benchmark called JMARK that tests different aspects of a media computer.  The HAL MC-3 scored ~500, which is on the low side, but my desktop machine scored ~1500, and it has the same buffering issues.  I'm going try out Foobar.

Foobar2000 will play DSD64 DFF files via the correct plug-ins with DSD DAC's.  You may need to unpack the ISO files to DFF format to use them.

That MS-3 may have the native DSD components loaded, but if not the Foobar2000 components needed are on the Hydrogen Audio Forum.

I have no idea what the JRMark tests but I ran my computer, my MS-3 and my MS-2 and got the following results:

PC,   2,134
MS-2,  512
MS-3,  525

The other thread indicated you are using (unless I misunderstood something which is possible ) the USB input of the Oppo BDP-105 DAC.  Per the manual (which I posted in the other thread):
"The BDP-105 supports up to 2ch/192kHz PCM signal through its USB audio input, and up to
2ch/96kHz PCM, Dolby Digital, DTS and AAC signal through its Optical and Coaxial audio inputs."

So the BDP 105 can't handle DSD via its USB DAC input.  JRiver allows one to convert DSD to PCM.  One must go to 'Tools,' 'Options,' 'Audio' and then 'DSP and Output Format' and adjust the sample rate for in excess of 192kHz to 176kHz and it will play the DSD as PCM.

ACHiPo,
After Phil's post, I checked the Oppo BDP-105 page and here is the link about DSD playback.

https://www.oppodigital.com/hra/dsd-by-davidelias.aspx (https://www.oppodigital.com/hra/dsd-by-davidelias.aspx)

They discuss that the way to playback DSD is via USB file input via a hard drive or thumb drive.  That also requires a later version of firmware to operate.  The audio output specs for USB input only state they support up to 24bit/192KHz PCM.

Been on travel a lot, so just getting back to the speaker project.

Ordered the Rythmik Audio HX800 amps for the two 6x12 servo subs from GR-Research.  Hope they will be on the way soon.

Just finished two DC coupled balanced input moded ChipAmp's for use in the OB planar part of the speakers.  Will be testing the amp modules soon with other speakers before building the second pair. 

Will get to the measurements after all the mods.

Hi Kemper,
Good to hear that Greg is building your GTA 2.5's.  Bubinga should look really good on the planars.  Will keep you posted on the speaker development.

The first pair of balanced input ChipAmps is making music with a pair of Lineaum LX-4 speakers.  They are a more challenging impedance load than the BG planars and are stable.  Next to build the second pair of amps and put some hours on them all to check stability before connecting them to the BG drivers.

Hi Rich! I just want to pass on some info that might be of interest for anyone else with an MS-1. I decided to upgrade my MS-1 from windows 7 to windows 10, and see what happens. well, it took a few hours to download and install, but when it was all done, everything worked perfectly! All apps and files were there, and all worked fine. Even Fidelizer worked as advertised. I have 10 on two other computers, so I am use to using it. I think the sound quality is at least as good as before, and maybe a tad better, but I need to listen some more to know for sure. Anyway, the upgrade worked and I am glad I made the change.

First test of the paralleled, DC coupled, balanced input ChipAmp modules for driving planars worked well without any change in DC offset. 

Have 12 ChipAmp modules built and tested.  Still 4 more to go to have 16 for 8 per side.  I really like the way they sound with the NEO3/NEO10 combo.

For all MS-1, MS-2 and MS-3 owners!  Do not install any other antivirus or malware software on the machines.  They already have MS Defender and MS Malware Removal Tool software running depending on Windows OS version installed.

If you install McAfee, Norton AV or any other software of that type onto the machines and it starts acting strangely, it is that software and should be removed.  If it kills the machine, I will charge for tech support and shipping.  Past versions of McAfee have even made it change audio buffers in playback and created glitch playback.

Will be rebuilding an MS-3 shortly with Norton installed.

The HX800XLR3 servo amps are up and running with the 2x12's. 

(http://www.audiocircle.com/image.php?id=135567)

Hi Rich,

1. Are you using SW-12-16FR drivers with the  HX800XLR3 amp. I'm planning to build either the H-Frame or the W-Frame. I was going to use the A370 amp but since there are two drivers I can see your reaasoning.

2. When I was emailing Danny, I mentioned that I would be using a DEQX Express II processer with the speakers. He suggested that I sell the DEQX and contract you regarding your MS-3 system. I also do digital audio recording and I've built a few computers so a computer system appeals to me. I would like to learn more about how you do dsp room processing.

Hi Charles,
For the 2x12 open baffle servo subs, the Rythmik A370PEQ is more than adequate to drive the SW-12-16FR servo subs.  I am using the HX800XLR3 with the large 6x12 open baffle servo sub array I am building.  You might ask Danny if the SW-12-8FR's would be a better match to the A370PEQ than the -16FR's in the 2x12's.  If you were going to more 12" drivers the HX800 might be a better way.  Each HX800 amp module is driving 3 - 12" servos in my setup.

The dspMusik is a 6 input (USB2, S/PDIF and A/D), 8 output DSP and HiRez DAC system.  It works as both a digital crossover and PEQ system for the setup.  I use Room EQ Wizard to make measurements with the MS-3 and dspMusik and then setup PEQ's in the woofer or sub processing.  Time delay can also be added if needed. The user can make measurements and I can setup the PEQ's and send the block diagram for AudioWeaver to run.  I use a Dayton Audio UMM-6 calibrated mic for the measurements with REW, as they are $85 and have calibration files compatible with REW. 

There are other ways, but I have to see the processing power available in the MS-3 and dspMusik will handle it on a case by case basis.

A friend that records and does his mastering is using the dspMusik in his Home Studio with a pair of GR-Research N2X and TL subs with his Protools system with very good results.

The user can make measurements and I can setup the PEQ's and send the block diagram for AudioWeaver to run.  I use a Dayton Audio UMM-6 calibrated mic for the measurements with REW, as they are $85 and have calibration files compatible with REW. 

There are other ways, but I have to see the processing power available in the MS-3 and dspMusik will handle it on a case by case basis.

A friend that records and does his mastering is using the dspMusik in his Home Studio with a pair of GR-Research N2X and TL subs with his Protools system with very good results.
So it's a little confusing on the Rythmik site on the HX800. It says "800W RMS (400W RMS x 2)". The 370PEQ will drive 3 -16FR's adequately, though it is a single channel amp. Is each HX800 2 separate outputs, with each channel driving three -16FR's, thus 2 HX800 amps driving all 12 of yours via 4 channels  :scratch:

Tom,
The HX800's have two separate sets of outputs and servo channels.  I am driving 3x12 servo subs per side with each channel for the total of 6x12.  Two full amps needed for the two arrays.

Does that make sense?

Oops, one more question. So does Brian install the OB shelf circuits in the HX800 standard or do you provide that in the dspMusic itself? Other than maybe the potential issue of wire connection length, one HX800 amp would be fine for two x3 separated arrays, rather than using two 370's.

Post by: HAL on 9 Mar 2016, 08:40 pm
Tom,
I bought my Rythmik HX800 servo amps through Danny, the shelving circuit was installed in the amps when he ordered them from Brian. 

The HX800 is mono input, so if you sum the Left+ Right channels in the dspMusik and send them to one output channel, it will work for mono subs as long as the wiring is short.  Two A370PEQ's are better if you need 3x12 arrays widely separated.  You want to keep the servo loop wiring as short as possible.

Hi Charles,

1. You might ask Danny if the SW-12-8FR's would be a better match to the A370PEQ than the -16FR's in the 2x12's. 

Brian says the GR SW12-08FR matched better for the HX300 amp. He said the A370 may over drive the 08FR. He said a better match for the A370 amp is the GR- SW12-16FR driver. Also, Danny is out of stock for the SW12-16FR. This all leaves me a little confused.

2.  I use a Dayton Audio UMM-6 calibrated mic for the measurements with REW, as they are $85 and have calibration files compatible with REW. 

I have a Earthworks M30 mic that is calibrated for DEQX



3.A friend that records and does his mastering is using the dspMusik in his Home Studio with a pair of GR-Research N2X and TL subs with his Protools system with very good results.

I have Samplitude Pro X software and RME hardware and a bunch of recording equipment. My RME Babyface has USB connections. And my DEQX Express II has an added USB audio card.

4. I'm thinking of building a beefed up W-Frame with 1-1/2" side walls for a lower profile.

Post by: HAL on 9 Mar 2016, 10:32 pm
Charles,
Brian is the expert in that area with Danny.  Danny might have a schedule for the new SW-12-16FR's if you contact him.  They are popular for the OB subs.

Have the HX300 servo amps here work with the 3x8" sub drivers in the H-Frame and U-Frame.  They are smaller size amps than the A370PEQ.  They also have mini-XLR balanced inputs that I like.     

The Earthworks M30 mic will need a XLR phantom powered mic preamp and USB A/D to input to the MS-3 to run with REW.   I have one here for my old DEQX 2.6P.  I have a calibrated UMM-6 mic that I can lend for use with REW if needed with the MS-3 and dspMusik purchase.

The beefed up 2x12 W-frames should be cool.

I do not miss the speaker correction of the DEQX as the DAC portion of that unit did not sound very good to me.  The dspMusik 2x8 has HiRez DAC's running at 24bit/192KHz with the Analog Devices ADSRC running for all digital inputs.  The ADC for analog inputs is also very good running at 24bit/192KHz. 

The question is how well things like Diraq Live will run on the MS-3 to do similar things to the DEQX.  That is something I am looking at now.

The MS-3 and dspMusik 2x8 combo is $2299.00 + shipping in the US.

The dspMusik can be used in two modes.

1) With the PC to load code and change it on the fly.

2) Burn the flash memory so that it is stand alone.  No more modifications.  Just then needs a PC USB ASIO driver or ASIO connection over USB for MAC.

What plays through the MS-3 sounds great (I'm on Win8.1), and it's running much faster since Rich worked his magic.  Unfortunately I'm still having network issues that limit the accessibility of the the content (I can "see" the MS-3 on my network, but haven't had the time to figure out how to get the HAL onto my Homegroup).  One curious thing is that even though my DAC (Gustard X20U) handles native DSD, when I feed it an ISO file from the MS-3 it displays PCM, which suggests I still don't have Foobar2000 output set up right.

orientalexpress has the same DAC.  He had to download a different USB driver than I found to use it with DSD.

You might talk to him for some ideas.

The Homegroup is probably not setup at this point.  It is in Control Panel -> Network and Internet -> Homegroup.  Check your Homegroup password on your other machine and use the same one for the MS-3. 

Also make sure Foobar2000 has the IPv4 xxx.xxx.xxx.xxx address in the HTTP control setting for remote webpage control.

Post by: HAL on 19 Mar 2016, 03:27 am
When running Dirac Live, the large level change makes it hard to compare the original and flattened curves. 

The target response curve that they are shooting for is rolled off across the frequency range for the on axis response that it measures.  It sounds to rolled off to me.  It can be modified by the user, so possibly flattening out the target response curve will improve the response for me.

Problem is can it be done before the 14 day trial time is up.  After that it is $440 for the license.  We shall see.

Interesting links.  Thanks for posting them.

The impulse response inversion technique has been done a few times.  Comparing the old Perpetual Technologies SOCS method of just correcting the speaker and the Dirac Live room and speaker is interesting, the SOCS method corrected to a flat response for the speaker and the Dirac Live corrects to a sloping response for the speaker-room system.  The latter is supposed to be the preferred in-room frequency response after room interactions.  Of the two, I prefer the old SOCS method so far. 

One thing about the Dirac Live method is that it does three measurements, left, right and both channels for the correction process.  The mic can only be pointing in one direction for all measurements.  If it would let you move the mic between measurements, you could try both correction methods and see which is preferred. 

The good news is that Dirac Live uses the Dayton Audio UMM-6 USB calibrated mic I already have.  Did not need to get another one, even though they recommend the UMIK-1 USB calibrated mic.  One thing I found is not to use a USB2 hub with the mic.  Had data stop a few times during the measurement process.

Will be interesting reading Floyd Toole's paper.  Don Keele's CBT paper is interesting as well for line array acoustics.

Have 20 of the modified ChipAmps built and tested for the open baffle line array.   

Will be gluing the baffle stringers and mounting the FPS drivers next. 

Have the parameters for the beamforming idea for the dspMusik digital crossover programmed and ready.

First step is 4 drivers per side and see what results I can obtain.

Have an Audiomatica CLIO 8 system ready to make measurements on the LS-9 crossovers at Forest Dwellers to make the dspMusik digital crossover design from the original.  The PC laptop is running the CLIO 8 software and the system is calibrated. 

The process is simple if the passive crossover is external to the speaker.  That is in process for his pair of LS-9's.

The amps will probably go in a chassis external to the speaker, or possibly use as the base.

The Dirac Live software has expired, so no more experiments.   Will be trying Math Audio and DRC instead.

Have a prototype of the dspMusik digital crossover for the Magnepan MG3.6 speakers running.  Had an enquiry about it, so did one from the manual's specifications. 

The MG3.6 is a three way planar, but only requires a two way crossover for the way it is actively biamped.

Many years ago had the passive external crossover for biamping my MGIIB's with a pair of Hafler DH220 and later ADCOM GFA-555 amps.  With a little EQ from my Hafler DH160 EQ, sounded pretty good to me.  Can do that so much better now with the dspMusik.

For folks wondering about the dspMusik HiRez DAC sound quality, if you ever heard the Dodd USB DAC that Gary built at RMAF or other place, this is a very similar design.  I helped Gary with the digital part of the design and he did the analog section.   

Danville Signal had the same DAC ideas and implemented something very close in the dspMusik for all 8 output channels.

On the MS-3 side, tried it with the Meridian Explorer2 MQA enabled DAC using Foobar2000 as a player.

I recommend downloading the free MQA encoded files from 2L and giving them a listen.  The recordings that they have remastered with MQA sound very good to me. 

The download costs are about the same as other HiRez websites, so I did buy some of the full recordings with very good results, even without the decoder.

While I have a MS-2 PC Music server, Rich has said that it is substantially the same as the MS-3. Both servers have the same design goals. The MS-2 is responsible for my digital playback having the same type of 3 dimensional sound-staging and holographic imaging that I have with spinning vinyl. Playback of music files using my Toshiba I7 quad-core laptop results in a much flatter sound stage, basically concentrated on the front wall of the listening room. The laptop also imparts a hardness in the midrange that is hard to live with.
 I imagine changing over to a MS-3 from a laptop should yield similar gains in sound quality and Rich's product support is outstanding.

For the LS-9 crossover measurements, here is the Dayton Audio ADA100 stereo power amp that will driver the passive crossover with Pocket CLIO as the measurement system. 

The unit has 60wpc and 5-way binding posts to make it easy to connect to raw wiring of an external passive crossover for measurements. 

As noted by others, it is important to have the speaker driver load on the passive crossover to get the correct frequency response plot to emulate digitally.

Will setup the measurement suite with a passive crossover to demonstrate the technique.

The Pocket CLIO measurement system is working and made it's first passive crossover measurement.  Wrote an instruction guide to go with it, so the user can get the measurements needed to create a digital crossover from the original passive crossover in the speaker.

Will be packing the system up and shipping it to the LS-9 owner to do the measurements on his speakers.

For PC based Music Servers, the MS-3 is a totally fanless and no moving parts solution to noise in the listening room.  The only time a mechanical system is running is when the DVD player is in operation for ripping discs.  Other than that it is totally solid state.

Another thing the PC platform also gives is the capability to add software like room and speaker correction and different music players that typically the streamer systems do not.  The system can also add capability over time as new audio ideas surface.
Title: Re: HAL's MS-3 Music Server and dspMusik 6x8 DSP crossover and HiRez DAC's
Post by: HAL on 1 May 2016, 10:59 am
For anyone wanting a larger library storage option, the MS-3 can be built with either a 1TB or 2TB internal SSD drive.  The prices are now very reasonable for both.

The MS-3 with a 1TB SSD is $1299.00, with a 2TB SSD is $2000.00 plus shipping.  The first 1TB unit was shipped last year with very good feedback from the owner. 

This makes a totally silent Music Server that can be in the system with a short USB cables to drive the external DAC into the audio system. 

A remote NAS can be connected by either Ethernet or WiFi to the system for larger storage needs.

The new MS-3 setups of Foobar2000 will be adding the Math Audio Room EQ capability.  This way customers can try it in their own systems and see the capability and sound quality.

For anyone wanting an excellent sounding small setup, the $299 Meridian Audio Explorer2 USB DAC and the MS-3 with the latest MQA decoding firmware sounds excellent.  It has both headphone and line level outputs.  Used it with my iFi iCan headphone amp and HiFiMan HE500's with excellent sounding results.  This DAC uses my preferred minimum phase filtering instead of linear phase filters. 

Have listened to many of the 2L MQA sample tracks and they sound excellent over the system.  This will also let you decode MQA from TIDAL streaming audio on the HiFi channel. 

After discussions with Math Audio, Room EQ will now be a standard component added to Foobar2000 for room and speaker correction.  Anyone with a MS-1, MS-2 or MS-3, I highly recommend giving this a try.  It needs a calibrated mic with calibration file, so there are a few options.  The easiest to me is the Dayton Audio UMM-6 USB mic since it is plug and play with Windows 7, 8.1 or 10.  Cost is under $90 from Parts Express. 

Here is the link for anyone interested in giving it a try.

First new HAL MS-3 with the latest version of Foobar2000 and MathAudio Room EQ is complete.  Only thing needed is a calibrated microphone setup.  I recommend the Dayton Audio UMM-6 calibrated USB mic for the system.  Once you have the mic you go to the Dayton Audio website and download the calibration file for your serial number.  The instructions for installing the calibration file are on the MathAudio website and are very simple to follow.

Looking forward to feedback on this one when it is purchased.  The stock HAL MS-3 is still $799.00 + shipping.

Fyi: There are some places offering 3rd party professionally calibrated files. I got my umik-1 from cross spectrum labs. For the in the room measurements I do, the slightly better accuracy (if any) probably doesn't matter much but it didn't cost much more. They sell the dayton mics as well. I read somewhere where Herb compared both of the mics and stated that the noise floor of the Umik was slightly better but can't find those posts. Anyways, both the Umik and the umm-6 are of excellent values imho.

The MS-3 demo went well and answering questions about operation at this point. 

Sent an updated LS-9 crossover file to the demo for trials.  Updated the maximum volume level to 100 percent.  Comments so far on just the crossover have been very positive. 

The next step is to run MathAudio Room EQ for speaker and room correction.  Sent simplified instructions to follow that worked well for a stereo seat measurement.

The updated LS-9 dspMusik crossover is up and running.  He is taking lots of notes on the sound to post once completed.  No woofer EQ like the original at this point, until measurements are made. 

Next step will be doing the measurements for MathAudio Room EQ and listen again with the correction running for changes.  It was not subtle here when I tried it, and did very well with the FPS drivers.

My last instock HAL MS-3 and dspMusik setup are now spoken for.  All new purchases will have at least a 2 week lead time for MS-3's and TBD for dspMusik's.

Just did a fun calculation about passive crossover costs.  Since folks seem to think Duelund make the best sounding passive components, did a cost estimate for a two way passive crossover based on the LS-9 design.

With all Duelund Cast copper caps, inductors and graphite resistors the total for a two channel crossover was $83,178.00.

Since the HAL MS-3 and dspMusik system costs $2299.00 + shipping, you save enough to by a Corvette, and will compete directly in sound quality with it.  Glad I moved into the 21st century for digital crossover designs.

The Windows 10 free upgrade offer is good until 29 July, so 23 days to go.  I would suggest making the decision early as download and install times are now about 4-6 hours. 

The MS-1 through MS-3 will all run Windows 10 64bit OS with no issues.  The MS-1 upgrade can be a little longer since it is Windows 7, where the MS-2 or MS-3 are Windows 8.1.  Have done two MS-1's now with very good results.  All the MS-2's and MS-3's here have been upgraded to Windows 10.  I just like the UI more than Windows 8.1.

The benefit for the MS-1's is that Windows 10 sounds better than Windows 7, so it is also a sound quality increase as well.

Anyone on the fence about this should make your final decision soon.  The upgrade price that I have heard after 29 July is $99.00 per machine. 

I still offer tech support on all the MS-1 through MS-3 that I have built.  I can help if needed, just let me know.  Will be doing that after return from CAF for one customer that is dropping it off at the show for the upgrade.

So far I have burned approximately 80 Redbook (and 1 HDCD) discs to the server.  The server has worked flawlessly.  I have over 200 hours of playing time on it so I feel it is well broken in....if any of you have considered taking the leap from a disc spinner to digital music I highly recommend Rich's server.  Although I still have a way to go to complete the transfer (rip) of my 600 redbook CDs to the server, making this transition to a music server with the MS-3 has been relatively simple.  In my case Rich loaded the Gustard X20 Dac software for me and loaded foobar, exact audio copy and the sound processing program (which I have not yet used).  So the dac was configured and ready to start ripping discs to without any manipulation on my part.  Getting the Gustard dac to read DSD 128 from foobar took me a couple of tries at the foobar settings but rich had installed the foo-asio plug in, I just had to set up foobar correctly for use with my Dac and driver.  Basically this has been a very smooth transition from redbook to digital.  My system has never sounded better.  I feel I have a high end digital sound stage when playing old or new music.  I haven't compared the sound of the MS-3 to other servers so I can't compare but I can tell you for the money I spent on the server with a 1TB hard drive fully configured to support my Dac I don't think I could have gotten a better deal anywhere.  (And I haven't used the sound correction software yet,....am waiting for the microphone via Amazon).  So thank you Rich for assembling a fine product and helping digital novices like me get into high-res digital.  This has been a huge leap in sound quality for me.  The detail I get from this front end is at times jaw dropping.  On a final note, Rich has responded immediately whenever I have a question.  If you are considering purchasing a server, keep the MS-3 on your list to try.

I just added some files to my MS-2 and MS-3 and also did some file re-tagging on the MS-2.  Neither machine prompted me for updates.  On other updates, they did not seem to happen (did not pay tons of attention) on the same day for whatever reason.

martinr,
I am glad that the MS-3 is working out for the music library! 

Just did my MS-3 demo system with Windows 10 Anniversary update.  Will see how all the software works after the change.  So far only a few UI changes in look and no problems with the update process.

For anyone wanting just to play a music CD in Foobar2000, just go to File -> Open audio CD and there is a window that allows you to play the CD directly from the drive. 

This allows the internal DVD drive in the MS-3 to be used directly when folks just want to play single tracks or the entire CD.  The track list will come up and the user can play any or all of them from the display. 

This was used for CD playback at CAF2016 for folks bringing demo discs.  Foobar2000 buffers the track before playback.

Folks bringing USB drives, just had to plug them in to access the music files.

Robin and I have been talking for a good while about the HAL Magical Music Machines.  He's going to be very happy with his purchase.

satfrat received his HAL MS-3 Music Server today.

Will be looking forward to his feedback once he has it integrated into his system.

satfrat has his MS-3 up and running with his hard drive library and DAC.  He is a happy customer from his comments.

Always good to hear from a customer happy with the system!
