Title: ModWright Oppo BDP-95 Mods?.....YES!
Post by: modwright on 22 Feb 2011, 05:31 pm
I am investigating the BDP-95 right now and working on a mod for it.  Please check back over the next couple of weeks and I will post more!  I just wanted to confirm that WE ARE going to offer a mod for this FINE $1K(?!) Unviersal player!

Thanks,

Dan

It doesn't appear to be much room in there.

Post by: modwright on 23 Feb 2011, 06:26 pm
As you can see, not a lot of room to put any new PCB's inside.  As a result, my first focus will be on the stock regulated power supply and the stock analog stage, to see how existing circuitry can be re-engineered for significantly better performance. A tube mod may not be possible as I simply don't know where I would put ONE tube, much less two.  But then again, we have been faced with more difficult challenges in the past and made them work.  :thumb:

My first effort however, will be a SS mod.  It will be a reasonable price, will not include a clock upgrade, because the ESS SABRE DAC chip in this unit has its own dedicated clock and I do not feel that it will be beneficial for this model.

It is ALREADY the BEST Oppo Universal that I have heard STOCK!  I am looking forward to producing a mod for this player that will offer a < $2K Universal option that will be EXCEPTIONAL!

Thanks!

Did some real work on the Oppo 95 mod today.

The first step is to see what we can do with the existing unit, without adding our own PCB.  There is SOME room, right above the drive, where a PCB of our own could be mounted.  This is really the only place that I consider noise free enough, to locate a new analog stage - tube or SS.

For now however, I went over the existing power supply design, analog stage and DAC and digital supplies.  The linear regulated supply is good and well done.  The analog stage, although op-amp based, is also very good and there are no coupling caps in the signal path.

I have so far removed one op-amp stage from the circuit and implemented our own op-amp free revision.  I then took the final op-amp gain/buffer stage and optimized its performance to work with our input stage.  This made a big difference in clarity, resolution and overall soundstage.  This could be done to all of the MCH and 2CH circuits.

I have a few more things that I want to experiment with and then I will likely wrap up the 'Level I' mod, which will be a high-value and affordable mod.

For those who want a tube mod, I need to see how we can fit a PCB in the space available and what would be required to do so.

Thanks!

Dan

Hi Dan,

This is great news.  Given what they've started with on this model, I figured you could come up a mod that doesn't require too much rework (hi value as you said).  Look forward to it!

Jim
Title: Re: ModWright Oppo BDP-95 Mods?.....YES!
Post by: modwright on 25 Feb 2011, 09:40 pm
You bet, I believe that we can make a number of meaningful changes to the existing unit and make it quite a bit better for a reasonable cost.

This is exciting stuff!

Thanks,

Dan

Post by: modwright on 11 Mar 2011, 08:56 pm
OK, I am debating about the initial non-tube mod.  I will do a final evaluation on this and the set a price.

As far as the tube mod goes, I blieve it CAN be done and I will get it done.  It will, realistically be about a month before the tube mods are complete however.  I have to design a new custom PCB to fit this unit.  The goal is to provide a tube circuit VERY similar to that offered for the Sony XA-5400 that is also fully balanced: Price = $2000.

Thanks,

Dan

Yo Dan,

I know you're busy but let's get crackin' on the TUBE version of the 95! I'm absolutely loving my 5400 but now I'm in need of an all purpose player for my video system. It'll be used for music on a regular basis so I'm hoping you can do to the Oppo 95 what you've done to the Sony. 

I was thinking of pulling the trigger on your modified 83 but I've been dragging my feet cuz I really want a balanced(XLR) player. When the 95 came out, I figured it was just a matter of time before you did a full tube mod(gotta be 6SN7s) and separate power supply but then you started talking about how tight the inside of the 95 is so I decided to put things on hold.

Now that you're convinced you can do the tube mod, I'll be looking forward to regular progress reports. As I said, let's get crackin'!

Regards



Title: Re: ModWright Oppo BDP-95 Mods?.....YES!
Post by: modwright on 13 Mar 2011, 09:20 pm
OK, crackin' I will be! 8)

I am actually going to wire up a 5400ES tube mod board into a 95SE and see how it sounds.  The PCB will have to be re-designed to fit the 95 and the circuit may be revised slightly, but this doing this will give me a quick way to evaluate the sonic potential of this unit and compare it to the Sony.

I will reply once I have done so and give a realistic timelien also!

Thanks!

Hi Dan,

I'm interested in the SS mod - only want so many tube pieces  :icon_lol:  Just curious how you think the 95 performs as a good old two channel CD player (although I'm more excited about the higher res formats).  I've recently let player go, as I'm doing computer audio through your Platinum TP.  But I wonder how this would be with CDs as occasionally its just more convenient - my personal reference point was a mid of the line Naim CD player.

Jim
Title: Re: ModWright Oppo BDP-95 Mods?.....YES!
Post by: modwright on 20 Mar 2011, 07:35 pm
I am very impressed with the stock unit!  Our SS mods offere a more natural presentation, refined low level detail and improved natural resolution.

I am working to finalize this now!

I can't comment on a mid-line Naim, but I can compare it to our other Reference units here and it is VERY good, especially relative to the price-point and value!

It is exceptional for CD's.  There are no capacitors in the signal path - no coupling caps.  It has a well done stock analog power supply (linear and regulated) and the chassis is both more rigid and better shielded than previous models.


As a Universal player AND as a CD only player, I think it is exceptional!

Thanks,

Dan

Have to wonder if they took some cues from you in designing the 95 stock!   :lol:  Look forward to hearing more.  Also wanted to let you know that there are some SS guys out here   :thumb:

This piece is about convenience for me.  With a tube primary source and pre, I look forward to just throwing any silver disc that exists in to this baby and sitting back and enjoying with no tinkering.  Although I will have to get another pair of liveline connects.  Love those things...

Dan, here's an interesting mod idea...  if the DAC and analog outputs are that good, could you add digital (S/PDIF or Toslink) INPUTS so we could use it as a DAC for our Squeezeboxes or other (non USB) music servers?

March 267, 2011 update!

Proto tube mod has been implemented and is being evaluated. Nearly identical tube circuit as used in Sony XA-5400ES, eliminating all op-amps from circuit, our own I-V stage (passive), offering both fully balanced and single-ended tube output.

Listening tests currently underway - more to come!

Thanks,

Dan

Title: Re: ModWright Oppo BDP-95 Mods?.....YES!
Post by: modwright on 30 Mar 2011, 06:45 pm
Final listening to be completed today.  PCB design complete and coordinated with unit as to size, dimensions and mounting location.

Expect to have details finalized by Friday (April 1st)!

Thanks,

Title: Stock Vs. Mod - Listening Results!
Post by: modwright on 1 Apr 2011, 01:00 am
OK, so I have had a chance to listen to the tube-proto mod Oppo 95 and a stock Oppo.

Both on redbook CD and DVD-A, via RCA outs only so far.
Same cabling used and same system.

We happened to have a pair of KWA 150 Signature Edition's running in mono to my Daedalus Ulysses.
Preamp was LS 100.

Using same cables, compared a stock Oppo-95 to the tube-modified proto Oppo 95.

What jumps right out at me is the increased soundstage depth and width.
Secondly, the low-level information and aural cues are simply much more apparent with the modified unit.
Detail and resolution excel with the modified unit, over stock, and stock is GOOD!
The key differences are resolution, micro-detail/dynamics, decay and a natural 'ease' to the music.

What I am hearing is typical of what we hear with the Sony XA-5400ES and other mods, vs. stock players:

The lack of feedback (inherent in op-amp based analog stages) and the clean and simplified signal path of our 6SN7 tube-based circuit with tube rectified external power supply, simply lets the music through.

Tomorrow I will compare the Opp-95 w/tube mods to the tube-modified XA-5400 heat-to-head.

Both mods use virtually identical tube circuit and identical tube-rectified and SS regulated external PS 9.0.

This a more sophisticated tube circuit than was used in the BDP-83SE.  The Sony 5400ES tube circuit is a PERFECT fit in the excemplary Oppo BDP-95!

Tomorrow we will also begin contacting people who have been waiting and asking about this mod.  Kristin has at least 30 contacts to follow up with initially.  We already have a handful of units in the shop.  The calendar will begin filling up tomorrow!

We will be offering a 10% discount to the first to schedule BDP-95 tube mods.

Tube Mod price for Oppo BDP-95 has been set: $1750 + shipping ($1995 w/MWI 'Truth' umbilical)

Thanks!

Are you still considering an SS mod?
Thanks
Title: Re: ModWright Oppo BDP-95 Mods?.....YES!
Post by: modwright on 1 Apr 2011, 07:48 pm
Hi guys, first of all, yes I am still considering a SS mod.  It will be more reasonably priced and will be available for 2CH and MCH (including 2CH).  Pricing and details to follow!

JUST FINISHED COMPARING SONY 5400ES W/TUBES TO OPP 95 WITH TUBES!

I would have to say it is VERY close.  Because of different DACs used and other differences in the players, there are subtle differences between them, but I would say that with the same tube circuit, it is really too close to call.  They are BOTH excellent!

Obviously the advantage of the 95 is that it plays all formats and has great video too.

It IS superior to our previous tube mod for the BDP-83SE.

Thank!

Dan

Title: Re: ModWright Oppo BDP-95 Mods?.....YES!
Post by: modwright on 3 Apr 2011, 09:54 pm
I will measure the height of the Oppo.  The outboard supply is: 8"W x 4"H x 10"D.

We are not upgrading the clock in the 95, as the SABRE DAC chip each have their own dedicated oscillator.  We do upgrade the digital power supply and power decoupling at the DACs to lower jitter levels, as well as add further mass and vibration damping to the enclosure and transport.

Digital input mods are expected to be available for the BDP-95 as well as for the BDP-83 and BDP-83SE.  This design is complete and PCBs are in-house.  We have only to do final assembly, testing and prototyping of the digital input mods.

Thank you,

Dan W.

Can you comment on the transport in the Oppo 95 compared to the Sony 5400es.

I have an Oppo 83 SE and a Sony 5400es and the Sony is much smoother and makes less noise.

Since you look inside these all the time are the newer transports in the Oppo 95 up to Sony build quality?
Thanks Gary

 
Title: Re: ModWright Oppo BDP-95 Mods?.....YES!
Post by: modwright on 4 Apr 2011, 08:22 pm
I am not sure if the transport in the 95 is different than that which is used in the 83/83SE or not.  What they did do, however, is to fully shiled and separate the drive and switched-mode power supply (separate from linear regulated audio power supply) with metal panels.  The drive itself is totally enclosed and shielded, which cuts down on noise.  There is RFI/EMI shielding as a result and also a stiffness which reduces vibration.

I have found the Oppo transports to be VERY reliable and it is for this reason, that I have pursued them.  The Sony transports are also reliable.

Both have a plastic tray and body.  SACD and Blu-Ray require the drive to spin at high speeds.  I believe some people found the 83/83SE drives to be a bit noisy at times.  The way the 95 is built with increased stiffening and shielding is such that I don't notice the drive noise at all.

Thanks,

Dan W.

Dan, I found these statements in the AVS forumn:

'But I need to fight with those 2 ESS9018 DACs first, here is the thing that I am fighting: http://www.flickr.com/photos/6059296...3076/lightbox/
HF noise in analog ground plane... Do not read this wrong! BDP-95 is a very very good player; however, with $1000, it cannot be perfect in every way. This HF noise basically compromised the LM4562 analog OP amps... '

Are these statements correct? Will you tube mods avoid this problem?
Title: Re: ModWright Oppo BDP-95 Mods?.....YES!
Post by: jwes on 7 Apr 2011, 04:44 pm
Hi Dan,

It seems at this point most energy has gone toward the tube mod.  What kind of expectations should I have for the SS mod in terms of approach, price, timing, etc.?  I'm excited about that one.  Think it will be my "all disc" player, and the TP will remain my computer/internet answer.

Jim
Title: Re: ModWright Oppo BDP-95 Mods?.....YES!
Post by: modwright on 7 Apr 2011, 06:07 pm
The tube mod will remove the signal from the analog ground plane, so this should not be an issue.

I am not HEARING the issue described, even with SS mods only.

I am fianalizing SS mods details this week and will post pricing and options tomorrow.  It will not include clock upgrade (neither does tube mod) and there is no need for our own PS as the supply in the Oppo is good.  As a result, cost for SS mod will be much less than for tube mod.

Thanks,

Dan

I would not sent it to Oppo.  They likely just exchange the units or replace the bad parts.  It the mods are attached to what has to be replaced, it would not be a good outcome.

If unit is in need of repair, you would send it to ModWright and we would do the following:

1) If failure due to our work - covered by 1 year warranty, parts and labor, less return shipping.

2) If drive failure or other issue that would otherwise be covered by Oppo factory warranty, we will repair for parts cost and minimal labor.  Shipping costs extra.

Hi..
SS mod applied to BDP-95EU, will that be possible to do by yourself ?
Since sending a unit to US through customes etc. would not be nice regarding to time and price.
I think there is a potential market in EU countries, endusers doing there own upgrade in the same way Nuforce launch there 93Nu/NXE units.

There is legal ways to get trought customs smoothly.
Maybe the best would be to ask MWI EU local distributor to manage to get BDP95s and send then to Dan.
But I know for facts that the man in change in England is real pain in the a**.

Better asking Dan to get the unit, add in a MRMZ module.
Cheaper and you'll get more stuff and earlier firmwares (current BDP93 EU does not recognize MP3 files, BDP95 will have the same problem).

We do not offer ANY of our mods in kit form I am afraid.

Hi Dan,

I'm waiting for my unit to arrive.  Just wanna make sure my balanced interconnects are long enough from the unit to my preamp by checking the photo from Oppo website.  So, have you changed any layout of the connections on the back panel of the BDP-95 after your mods? 

Also, did you measure the power consumption of the tube PS (mine is 220V-240V)?

BTW, Kristin has been a great help in making me a proud owner of ModWright products for the first time.   :thumb:

Thanks,
Klao
Title: Re: ModWright Oppo BDP-95 Mods?.....YES!
Post by: modwright on 21 May 2011, 08:16 pm
We do not change the layout of any of the connectors.

I still have yet to measure power consumption, thank you for the reminder.  It is no more than about 100W for the external supply and less for the actual player I believe.  200W max should be adequate.

Thank you for the comment about my Executive Assistant, Kristin.  She is a great asset to ModWright and reflects the qualities of ModWright that I have always strove to maintain.

Sincerely,

Dan W.

Hi Dan,

I just received my units today in good order.  Thanks again to everyone in ModWright camp.  :thumb: 

Funny, but I've always thought that your tube modded Oppo player would be powered solely by the PS 9.0 unit via umbilical.  I found out I was mistaken when I couldn't turn the player on without plugging the power cord normally as well.

Some questions:
1.  Do we strictly have to wait 45 seconds after powering up the PS and all tubes before turning the Oppo on?
2.  Can the player operate if we forget to switch on the PS 9.0?
3. Is there suppose to be a LED to indicate that the PS 9.0 is operating?  The unit I got has a hole in the front panel above the "PS 9.0" screening.

As for the power consumptions, I gauged them roughly through my power conditioner / voltage stabilizer whose display shows power output in Amps.  When the PS 9.0 is switched on, it draws about 0.2 amps.  When the BDP-95 is turned on, it draws another 0.1 amp.  But when I checked the power consumption spec in Oppo manual, it says 45 Watts.  So if the PS 9.0 and al the tubes draw roughly twice as much, they should use around 90 Watts.  My guess is altogether both the player and PS would consume about 135 Watts.  Have you had time to make the measurement yet?

Cheers,
Klao 
Title: Re: ModWright Oppo BDP-95 Mods?.....YES!
Post by: modwright on 17 Jun 2011, 05:59 pm
Hi, yes, there are two power cords required.  The reason for this is that I wanted to COMPLETELY separate the tube supply from all other internal supplies.

You do have to wait the requisite 45 seconds for the voltages to stabilize before our analog stage comes out of mute.

You can operate the player by itself for MCH and digital out - all but 2CH analog outs - without tube supply being powered on.

There IS an LED installed.  It is press-fit into a plastic bezel in the faceplate.  It is possible that it popped out in shipping.  Please remove the PS cover and verify.  It is wire-leaded to the PS board (the LED) and then press-fit into a plastic bezel in the faceplate.  If this is not the case, please let me know and we will send out a replacement immediately.

Thank you,

Dan W.

Thanks, Dan.  The LED and the attached wire are inside the PS unit.  I put them in place now.

Is the screening on the back about replacing fuse rating/type, 1A slow blo, corresponds correctly to the 220V-240V unit?  Just wanna make sure. 

Also, how does the current flow (some after-market fuses claim to have direction) thru the fuse, from back of the unit to front, or vice versa?  Or should I not worry about it at all?   :scratch:

Dan:

What is the size of the output capacitor in the tube mods?

I plan to try different brand or size of capacitor and see if the sound can be improved.  Is the capacitor located before the buffer stage?

Thanks
Title: Re: ModWright Oppo BDP-95 Mods?.....YES!
Post by: modwright on 21 Jun 2011, 05:19 pm
It is 1UF-400V MWI metalized oil-impgregnated poly (x4 -for balanced outputs) and is after the gain/buffer stage.

Thanks,

Dan
Title: Re: ModWright Oppo BDP-95 Mods?.....YES!
Post by: dchan88 on 21 Jun 2011, 06:53 pm
What could be the possible effect if I replace the 1UF capacitor with 4.7UF capacitor? Anything negative?
Title: Re: ModWright Oppo BDP-95 Mods?.....YES!
Post by: modwright on 22 Jun 2011, 10:13 am
If it will FIT, there is no negative.  Space is VERY tight inside the unit and all four of our 1uf MWI caps are board-mounted on a custom PCB.

Thanks,

Dan

I am curious because from the picture of the XA5400 mods, I can see it is using the bigger capacitors.
Title: Re: ModWright Oppo BDP-95 Mods?.....YES!
Post by: modwright on 23 Jun 2011, 04:18 pm
The Sony does use larger capacitors as there was more room.

We have measured and tested the Oppo and believe me, the bass response DOES NOT suffer.  In fact, it has deeper and tighter bass than the Sony in head-head comparisons.

This is with our preamp with 50K input impedance.

Thanks,

Dan

For a while I have been looking at a Fantastic CDP/DAC, CAS/DAC solution. Some of the system being tracked was the EAT Acute III, AMR 777, PD MPS-5 (Kidding - too expensive), etc. I also looked at
the Oppo BDP-95 . As I could not fully appreciate the specs I assumed that it would not work as a DAC for CAS; hence dropped this.
Then I read that you were already modifying the BDP-95 and my lips started smacking.

Kindly confirm if the modification make any changes to the lack of above CAS/DAC interface, or was I wrong - this was already stock option. work like a DAC.

if so either way the ModWright modification looks like one helleva strong contender.

Hi, the tube modified Oppo 95 is a fantastic player and we have made QUITE a few people VERY happy with it.

The stock unit will allow for USB or eSATA input from an external storage device, but just not from a computer.  Our mods do not change this.

How about a mod that would let you put a SACD or any CD or DVD in and send it to your hard drive wirelessly ?
Title: Re: ModWright Oppo BDP-95 Mods?.....YES!
Post by: modwright on 23 Aug 2011, 04:04 am
That would indeed be a trick feat!  First of all, there is the SACD copyright issues to deal with.  Secondly, I am not sure what wireless format would allow you to transmit data of such bandwidth.  Not saying that it can't be done, but I am not an expert in wireless data transmission.

Dan, can you (and/or someone else who has the modded player) describe the sound of the *solid-state* modded Oppo 95 vs. the stock?

I am still trying to decide between tube & solid-state mods but, my impression thus far is that the 95 is sooo good stock that the SS mods might be "enough" for me.

Thanks!
Title: Re: ModWright Oppo BDP-95 Mods?.....YES!
Post by: modwright on 5 Sep 2011, 03:55 am
They offer a very nice improvement in the sound.  There is less fatigue and a broader soundstage.

We have also had EXCELLENT results installing the Bybee rails in the DAC supplies in these units ($225 for bybee rail, installed).

The tube mod IS better, but the 2CH SS mod with DAC bybee rail installed is also a VERY nice upgrade.

I hope this helps.

Thanks,

Dan

By "EXCELLENT results" what do you mean?
And is that w/a already moded unit or a unit w/no other mods?

I'm not sure if your saying the Bybee mod is included in the price of SS Mod (or not).
Is the Bybee mod included in the tube mod (price)?
Title: Re: ModWright Oppo BDP-95 Mods?.....YES!
Post by: modwright on 6 Sep 2011, 05:41 pm
When I refer to the imrpovemetns of the Bybee rail mod, I am speaking IN ADDITION to standard mods.  It is not included in tube mods for SS mods.  It is something that I have only fairly recently had the opportunity to audition and determine the sonic benefits.

At RMAF, I will be doing A/B demo's of stock Oppo 95 and tube 95.  The SS mod 95 will be used in the Fritz speaker room.  I have never done a stock vs. modified A/B  :duh: and it is about time!

I also will have a full representation of our line, so will be able to do other product comparisons.  These 'shows' wil be scheduled throughout RMAF and times displayed on the door.

Tube Rolling Q:

Any 5AR4 and 6SN7 tubes too stay away from; because of size, fit, etc?
Title: Re: ModWright Oppo BDP-95 Mods?.....YES!
Post by: modwright on 7 Sep 2011, 12:49 am
Thanks!  I try to indeed walk the walk!

Most 6SN7 and 5AR4/GZ34 variants will fit in the LS 100 and in our modified Oppo 95 and Sony XA-5400Es.

Once you get into some of the other rectifier variants, such as 274B, 5U4G, 5V4G, there CAN be some design issues that need to be considered.

Thanks,

The photo of the 95 tube mod has a pair of N.O.S.:
JAN CKR (Ken-Rad) 6SN7GT (are they VT-231's?)
I believe the unit is shipped w/Electro-Harmonix tubes.

When your evaluating, are you using the E-H's or the K-R's?

Q:
Those would be the Russian re-issues, correct (for both: the 5AR4 & the 6SN7 pair)?

Which Sophia for the  rectifier?
Are you familiar w/the grades?

Thank you.

Fun Fact:
I just became a TubeHead last yr; w/the purchase of a 'Flintstone' headphone unit.
My 1st chance at rolling; I went w/W.G. Telefunken's for the German integrated.
How could I go wrong?!?! ;-)
Worked out GREAT!


Just (9:09PM PST) won, paid too much for actually, a pair of K-R VT-231's.
I've gone on a rampage in the last week, buying 9 pairs & 1 single; in preparation of your tube mod.

Post by: modwright on 15 Sep 2011, 04:46 pm
Russian re-issue Tung-Sols and Sovtek 5AR4's, that is correct.

I like the Sophia Electric 6SN7's and Mullard, Amperex or Philips GZ34(5AR4) as tube upgrades.

Old School meets New School; too cool!

I've got an even older school coming; Holland GZ34 black base (1949).
(& not one of those Mullard Blackburn UK for Germany/Holland fakeys either! ;-) )
I figured too buy now, as prices seem too only be going up.
Some 6SN7's I've just got have gone from like forty too hundred + in six months.
And just try too find a true Holland NOS metal base 5AR4/GZ34 for under two hundred bucks!!

Hi NutBuster,

I could be wrong, but I think your early production black base 5AR4 / GZ34 (Holland made) is likely 1959 production. The double 'D' getter metal base production was from perhaps 1951-1957 and was followed by the brown and black base of the same tube with the double 'D' getters.

Here is a great Philips production site with dates and photos:

http://www.tube-classics.de/TC/Tubes/Valvo%20GZ34/GZ34.htm

I am a fan of the metal base 5AR4 / GZ34 although the internals of the earliest plastic (brown/black)versions are IDENTICAL to the metal base with double 'D' getters and smooth plates.

Is clearance space of about 1.25" or 3.0 cm. above the PS 9.0 unit provide enough ventilation? 
There is plenty of space around the unit on the rack, but only that shelf level is just 15 cm. high.

Yes! '59, not '49. Good catch & thanks for clarifying. :duh:
Yes, again; I've already got that site on my faves.
Saved me a BUNCH of $$$!!!
(not mistaking UK's for Hollands/whether it said "Holland" on the tube or not)

When did you start buying GZ34?!?!
If I may ask, how much were you paying (ugh; I KNOW this is going too HURT!) for metal bases?
Have you done an Holland vs. UK shootout???

If you were going for tubes for this unit (abet w/o hearing it 1st) what might you roll w/?

Post by: JG2 on 18 Sep 2011, 06:21 pm
OK.......... I began buying 5AR4/GZ34 (Mullard / UK production and Philips / Holland production) when Dan  added a tube rectified PS to the players and SWL 9.0 linestage about 7(?) or so years ago.

I bought a few metal base versions from Germany and other areas of Europe using German E-Bay as well as searching other European E-Bay sites. I figured if this was where they were produced, there may be more available and I did pretty well. I bought most 'used/tested' and only had one go bad on me in a short time. The seller was a true gentlemen and replaced it as had more in his stash! The only true (who REALLY knows?) NOS metal base I bought was VALVO branded with Holland production code and tested off the scale on my tester and I recall paying just about $200 for it. All the rest of the metal base were from perhaps $120-$180 or so. All tested very strong.

As far as finding the early Holland production plastic base GZ34 / 5AR4 that have the same apparent internal construction as the metal base, look at the photos on the site I linked to. Be SURE the etched code on the glass or bottom of the base for some versions is Holland production (X for Sittard or L for Brusels.......... not 'B' for Blackburn, British production), and has double 'D' getters. The plates will look like the later metal base versions as production shifted from the metal base to the 'modern' (and more reliable?) plastic base with the identical internal construction as the metal base. Some folks, with more time on their hand than myself, feel the early double 'D' getter Philips (Holland production) tubes made right after the metal base sound as good as the true metal base and they may be right!

JG2,

So Dan got you too?!?!
My only previous rolling was one Telefunken (which went well w/the Tele power tubes, German amp, & German 'phones & sometimes even German CD's).
Were you paying 200 bucks a tube back-in-the-day?
Have you done a metal vs. blk/br shootout?
Holland vs. UK shootout?

My excessive tube rolling this month*:
6SN7
RCA Gray Glass 3pr.
GE Short Glass 2pr.
Mouse Ears 1pr.
Black Glass 1pr. [Ken-Rad]
Sylvania Chrome Dome 1pr.
Sylvania Gray Glass 1pr.
Sylvania Off Brands 1pr. [Shield]
GZ34
Mullard MINIWATT [Brussels]
Bugle Boy [Sittard]


I'm going for the "best" European rectifier tube + the "best" pair of US pre-amp tubes.
If you have any suggestions, much appreciated.
I'm thinking (not always a good idea ;-) ) the tubes will outlive me.
As there only powering a DVD player (can you believe it! :-0 ).
Not a twenty watt amp.
What's your take on tube life for similar devices.

* as you can see, I'll become a tube seller, soon!!

EDitEDbyED:
It's worst than I remembered.
10 pr. 6SN7's

Get yourself some NOS 6SN7s to really make it sing. I have the MWTP and the best I have gotten it to sound is with either a pair of Mullard ECC-32s, TS BGRP VT-231s or Sylvania 6SN7Ws with a metal base.

Enjoy.

Just a couple of questions to my fellow Circle-ites......

- Any specific feedback from the show on the comparison of the stock Oppo 95 to the Modwright 95 with the tube stage?

- Anyone in the Chgo area, or within a reasonable drive, that has the Modwright 95? I have the stock 95, and I am seriously considering the upgrade; I have been using my Modwright 9000ES for years now, and it's a killer cdp, however very limited in it capabilities compared to the Oppo.  I would really like to compare the players to hear if its worth the upgrade.

Cheers,

dminches (, NutBuster, and all),

You may have heard my MWI 95.
Both NutBuster's and mine have (in addition to the tube mod),
the SS multichannel mod, Bybee Music Rails mod on both
ESS 9018 DACs and the Modwright Truth Umbilical cord
(and region-free).
I had Dan install an Oyaide "Power Inlet R" on mine, which is
probably the only difference between our two MWI 95s.

Really looking forward to receiving mine and listening this week!

Enjoy the music whatever way YOU like.

I notified Dan concerning the firmware upgrade referenced below and he said he would install on both our tube modded MWI 95s prior to RMAF (and presumably on the stock Oppo 95 used in A/B comparisons to keep the playing field level).

The v. 1.5 user's manual also referenced below (which has a link to download it) provides new information re what some of new features are in the latest official firmware:

Speaker distance settings are now individual (no longer linked as pairs !!!)
and distance settings precision are now possible to 1/4 foot instead of 1 foot.
And I think the center and surround (side and rear) (and possibly subwoofer?) speaker distances are no longer restricted to have to be less than or equal to the front left and front right distance(s).

As I mentioned some days ago in other thread(s?),
choosing the audio processing option for stereo output as "FL/FR"
(it's now on page 74 in the new v. 1.5 users manual) will allow use of the Modwright tube mod and the quadruply paralleled/"stacked" ESS 9018 "stereo"  DAC for the audio of front channels of multichannel source material such as SACDs, Blu-Rays, DVD-As, and DVD-V w/MC soundtracks.
You run a pair of ICs from the dedicated stereo outputs and do not use the m/c FL/FR outputs, thus using one less pair of interconnect cables as well!

This setup only works if you one pre-amp with is used for both 2 channel and multi-channel.  In my set up I am using an LS-100 for 2 channel and a Classe SSP-600 for multi-channel via the HT bypass.  Thus, I need to have 1 set of LF/RF going to the LS-100 and a second going to the Classe.

dminches,

I am running LS 100 for two channel and FL/FR of 5.0 multi-channel
with current Modwright Oppo 83SE (full SS mods) via two pairs of ICs to two inputs of the LS 100.  Center channel goes to one channel of Modwright SWL 9.0 Signature linestage and left/right surround channels go to a PS Audio PCA-2 preamp.
Volume levels are adjusted/synchronized with AIX setup disc and SPL meter...

Post by: dminches on 18 Oct 2011, 06:54 pm
I don't follow what you are saying.  Are you using an LS-100 AND an SWL 9.0?

With my Oppo 95 I run the analog L/R to the LS-100 and the 8 channels (7.1) to my pre-processor.

I'm thinking (not always a good idea ;-) ) the tubes will outlive me.
As there only powering a DVD player (can you believe it! :-0 ).
Not a twenty watt amp.
What's your take on tube life for similar devices.
Never "replaced" old/worn out tubes B4.
Any guesstimate on how long a GZ34 and/or a pr of 6SN7's would last in a MWI 95?
Of coarse climate, temp, whatever comes into play; just a rough est.
BIG thanks.

NutBuster,

The NOS Mullard/Philips/Amperex GZ34 if test strong should last quite a few  years. 
Depending on the circuit Dan used in the tube mod,
it may only use one side (half) of each 6SN7,
if so then in a few years you could swap the tube positions and
have "like new old stock" all over again...

Post by: rlmacklin on 23 Oct 2011, 12:37 am
Looks like both sides of each 6SN7 are likely used
as the tube mod analog output circuit is differentially balanced.

Thanks 'Brother'!

I'm getting some nasty noises out of my mod.
When putting a disc in the tray, I can hear it though the spks.
Tap the top of the case & it sounds like I'm tapping the tubes themselves.

I've work around some valve equipment B4.
deHavilland,  Rouge, Mesa, Carver, Quicksilver, & Antique Sound Labs.
Even the ASL units weren't this 'alive'.

Going too switch out the tubes.
As well as load a disc w/the PS 9.0 off.
Try too isolate it more & report back.

UPDATE:
EDweird!
I was unable too recreate the microphone effect from the tray.
Started the 95 w/o the PS 9.0.
No 'tube-like  noise' ; of coarse.
However I did hear the tray closing noise thru the spks.
Then w/the PS 9.0 on, repeated loading & closing the tray.
No noise from dropping the disc in; only the sound of the tray closing thru the spks, again.
I don't know if "all" 95's" make this 'sound'.
However, unlikely mod related.

I did not tap on the cover again.*

Didn't mean too scare everyone.
(Happy Halloween)
Just freakED me out!

What I was really worried about was that it was the beloved KEN-RAD's.
Would've been bummed if I had too switch 'em out.

* The reason I tapped on the cover was because when I rolled the GZ34 into the PS 9.0 the top case rang like a bell.
(just unscrewing the bolts made the case ping & ring)
I was shocked the case didn't have any "enclosure vibration damping" ala the 95 mod casing reportedly has.
(I'll look into something for damping)

Back too the movies & music.

NutBuster,

I saw somewhere else that the rectifier tube
(GZ34/5AR, etc.) should last 10,000 - 12,000 hours
and to expect 5,000 - 6,000 hours from a set of signal tubes (6SN7s).

Try some Herbie's Audio Lab
Tenderfeet or IsoCups w/ Lampblack Balls
under the tube mod power supply
and under the MWI/Oppo 95
and one or two Herbie's
"SuperSonic Stabilizers" on the top of each.

http://herbiesaudiolab.net/compfeet.htm (http://herbiesaudiolab.net/compfeet.htm)

"Herbie" is Steve Herbelin who is excellent to work with.

Consider Herbie's Ultrasonic RX tube dampers for all the tubes as well

http://herbiesaudiolab.net/tube.htm (http://herbiesaudiolab.net/tube.htm)

(When I recommended these on one forum for my SWL9.0 Signature,
the recommendation was seconded by Dan Wright of ModWright).

95 Tube Mod'ED Brother,

I've tried tube dampers B4.
Didn't like the effect.
I know many like the "blacker backgrounds" they get.
I thought it was 'darker'; just at the cost of 'air & openness'.

I've still got em.
So, it's a 'free' tweak!

As always thanks & enjoy.

For some reason Dan's modded players are very sensitive to microphonic tubes. I also had the same promblem with Kenrads and 1950 black plate tungsol. When I opened and closed the drawer you could hear the noise you notice through the speakers. The answer is to find non microphonic tubes.

I've heard, ha, ha, the short 6SN7's are less 'noisy'; got two pr I'll have too check-it-out.

Tube mod Brother/NutBuster,

oppo-95-region-free-instructions file downloaded from ModWright webpage:

"User manual, Oppo BDP-93 / 95 PRO kit
How to use the mod:
• By default, your bluray player is region free for DVD. To set the bluray region to A, B or C, please
press 1, 2 or 3 on the remote when the player is in standby. The player will automatically power on,
when 1, 2 or 3 is pressed. The selected region will be stored and remembered, even when removing
the mains supply from the player.
• To disable the automatic power on, press the blue button on the remote once.
• To enable automatic power on again, press the yellow button once.
How to change the remote control code used:
If you have more than one Oppo player available, you can select the remote code address that the
regionfree kit must respond to.
Please note - when you change the remote code setting on the regionfree kit, you will have to select the
corresponding code on the remote to change the code again.
When the player is in standby, point the remote towards the player, and press the following keys on the
remote:
TOP MENU - SETUP - RED - X (Where X is remote code 1, 2 or 3.)
Remember to change the switch on the backside of the Oppo remote control to the same setting, and
also in the setup menu.
How to update the firmware on regionfree kit:
If needed, the regionfree kit can be firmware updated, please note that this is not the same as the
players firmware.
If there is a new firmware available, you will receive or download this image file: “bluimage.frm”.
You will need a standard FAT or FAT32 formatted usb memory stick. The firmware update file, is named
“bluimage.frm”. Copy this file to your usb memory stick, please do not rename it. There can be other
files on the usb memory stick at the same time.
Once copied to the usb memory stick, insert it in the front usb connector of your player, only the front
usb connector can be used. When the player is in standby, press the following keys on your remote :
TOP MENU – SETUP – RED – 9
Now your player will automatically start up, and read from the USB memory stick. If there is a LED on
your USB stick, it will flash for several seconds while the firmware is updated.
After approx. 20 seconds, the regionfree kit is updated. You will have to power off the player, to let new
firmware work."

My Mod Bro,
BIG help!
I've been killing myself tonight w/region error disease!
Neither new disc I got tonight would play.
I've been having probs since getting "Pulp Fiction".
No "CC" BD's would play.
Couldn't get a Fox BD too play either, maybe five or six, till "Alien".
Very frustrating.
Especially the fact I'm in R1 & its the R1's that wont play!!
No probs w/any 'import' discs.

EDweird that some old & new R1's would play & some old & new R1's wouldn't play?!?!
So, I didn't think it was a region related prob cause all regions that I have did play (again, just not all R1's).
I hope this doesn't mean I have too change the region while in standby for every diff region disc or "CC" I own.
Pain!

Looks like tomorrow is "PF", "The Day The Earth Stood Still" (both), "Die Hard", "Beneath the Planet of the Apes", Cast Away", "Everything Must Go", & all "CC's" BD movie night!  :thumb:

Hi All-

I've had my Modwright Oppo 95 for several months now and I was wondering if anyone has done any direct comparisons of playback from disc media vs. file-based playback on this unit? I've had a couple of listening sessions in my listening room with multiple colleagues who are members of BAAS (Bay Area Audiophile Society) and in our activities in comparing the quality of playback the group came to a pretty clear consensus.

The findings were that disc-based playback was definitely inferior to file-based playback on the Modwright Oppo 95. It was the feeling of the group that the comparison wasn't even close. For an example of one comparison we played the Channel Classics Ivan Fisher Mahler Symphony No. 2 on SACD vs. 192/24 version and the conclusion was that the file-based performance was so much more refined and exhibited more control and presence/energy vs. the SACD. I realize that we're dealing with two different formats so the next thing I did was to take a CD that I had and I ripped it using DBPoweramp to FLAC format for playback on the Modwright Oppo 95 with the goal of comparing the CD playback with the FLAC file-based playback of the same material.

Once again, the group came to the conclusion that the file-based playback was much better in the quality of the music reproduction in comparison to the source CD playback. Has anyone (Dan included) found this to be the case with their experience thus far with their  modded Oppo 95 unit? I haven't seen this discussed at all thus far and I was curious as to why this is the case. Or others not finding this to be the case and thus the reason for not raising it?


Thanks,
Tracy

P.S. By the way I forgot to mention that I think the Modwright Oppo 95 is a terrific value for the level of performance it provides given its price point. My fellow BAAS members actually think it's a steal! My systems is "sort of" high end and this $3K front end piece definitely holds its own with the rest of my system.

Just for reference my system includes the following:
Modwright Oppo 95 (upgraded umbilical cord, Mullard GZ34, Sophia Electric 6SN7)
Joule-Electra LA-450ME preamp
Plinius SA-103 mono blocks
eFicion F300 with Stillpoints SS Ultra under woofer and satellite cabinets
Synergistic Research Apex cables (interconnects, power cords, etc.)
ASC Basstraps
First reflections panels on side walls, ceiling and floor covering, back wall GIK bass treatment
etc.
You get the general idea ...

I ripped numerous cd's to flac and compared playback on both a stock Oppo 93 and 95 and found the flac versions (on USB stick) had a more analog sense of ease and flow, while being more resolving on both ends of the frequency range.  That was the tipping point in me seriously looking into a server based system of some kind.

I bought the Demo Oppo modright modded cd player from RMAF. This player sounds fantastic as a redbook player after 500 hours of play. It sounds good in the beginning, but after the 400 mark watch out. It is very important how you isolate the modright from outside vibrations to get the best sound. I have tried a lot of different footers and came up with using German Acoustics cones (brass with chrome inserts) sitting into the German Acoustics rubber feet. You place one directly under the front transport drawer area and two in the back. This really smooths out the player, opens up the soundstage and gives way better focus. I have not tried computer downloaded music yet, but I bet you would have liked the sound as a cd player better with these tweaks. I am using Coincident power cords with the unit and Dan's new umbilical. I also have three German Acoustic spikes under the power supply and both rest on thick maple wood shelves. I am using new old stock tubes in the main unit and the power supply.

I had Modwright perform the 2 channel solid state mod ( to include installing the Bybee rails on the DAC power supply) back in October.The unit now has several hundred hours of burn in and approximately 60 hours of listening time (It would have been more but we had house guests during Thanksgiving, Christmas and New years.). Long enough to do a fair valuation. Because I live in Denver and recently attended the RMAF for three days, my frame of reference would be the stock Oppo 95, the Modwright tube modded Oppo 95 and the multitude of digital front ends that were at the show.
The difficulty in doing this review is that these mods were done to an already outstanding player ( I would recommend the recent review by Gary Gallo In AudioXpress). That being said, I thought that the improvements that Modwright made to the player were very worthwhile. The soundstage became wider and deeper, the delineation of instruments and voices was greatly improved and the bass tightened. All in all the Oppo became more musical and enjoyable. Its hard to see how you could do better for the money.

I have had my Oppo BD-95 with the tube mod and upgraded cable for a few weeks now.  I am totally floored that the overall improvement this update provides.  All digital media sounds significantly better (CD, SACD, DVD, and Blu Ray).  The overall presentation is as good as any digital source I've ever heard, and better than anything I've owned to date by a large margin.

All portions of the playback sound very natural.  The bass is deep and tight, midrange is transparent and liquid to the point of "you are there" realism.  The treble is as clear as can be, with no artifacts whatsoever. 

Replaced the stock tubes with JAN Sylvaina Brown Base tubes from the 50's, and a NOS Sylvania 5AR4 fat bottle.  The tubes further improved performance. 

All in all, could not be happier with this player.      :thumb:

Dan, it's great to hear you're moving forward on this. 

Will you still be incorporating a toggle switch on the back?  That's a concern for me, as my BDP-95 rack placement makes it difficult to access the back panel.

Any chance you could mount the toggle on the left or right (rear) side?
Also, how many digital inputs did you end up squeezing in?

2. I'm also wondering if there is any kind of "fix" for the fan noise.  In my quiet environment, I can hear it from 12' away.  What is worse, though, is that I am stuck with sitting about 2' away from the player. 

Thanks!  Answers to both questions will help immensely, as my first issue is being sure I am going to keep the player.

I also have a 95 but I didn't even know it had a fan. Is the unit in a cabinet or rack?  It really shouldn't be that loud.

I agree the fan noise can be annoying.  At least one modifier (not Modwright) make a "cage" to replace the Oppo's cover, which he claims allows the fan to be on much less of the time.

In my experience, I have to have my ear right at the unit to even hear the fan noise.  Perhaps Oppo started using quieter fans.  I have NEVER found the noise objectionable and given the heat of the video chips, it IS there for a reason!

Thanks,

Dan

I have had my BDP-95 for over six months now with about 400 hrs. on it, and it's sounding more open and a little smoother. The fan noise is an issue with me as well. I contacted Oppo twice regarding the fan noise. They stated: "There have been no running changes to the fan of the player. It is possible that you are susceptible to hearing the fan noise of the player, while other customers are not. According to our records we have not yet repaired or replaced a player for excessive fan noise and have found the fan to actually be defective."
I find that somewhat dismissive. Ya, I am also susceptible to high "Total Harmonic Distortion", and low "Signal to Noise Ratios". :roll:
It really should not be an issue with such a fine player and it's the main reason I can't see going ahead with a mod to the player until it's fixed somehow,(a ModWright fix perhaps?)
I would let Oppo know if you have an issue with the fan noise.

Thanks everyone.  I just bought the player, so Oppo apparently has not made any changes to the fan.  I think maybe I have a more quiet environment than some.  I can’t imagine not being able to hear the fan from a couple feet away. 

*Does anyone know how long it takes for the unit to sound it’s best?*  It sounds a little strident at the moment.

If you run the Oppo with its cover off it sounds better and the only time the fan will come on is when you are playing a Blue Ray.  A thin wooden top cover (dust cover) also allows more cooling and therefore no fan noise except blue ray play and almost sounds as good as no cover.  I am experimenting in the next week with a replacement fan and it might be better.  If it works then I will come back here and let you know what the fan is, where to get it and how to replace the stock fan.
Title: Re: ModWright Oppo BDP-95 Mods?.....YES!
Post by: modwright on 12 Mar 2012, 06:29 pm
Thanks Ric!  I would caution, only with our tube mods, about a wood cover, due to tubes and heat.

A fan that operated at a lower RPM and yet could still provide adquate cooling, is one way to lower the noise.  Also, better bearings!  The trick is to fine a fan that is the same size and will still provide aequate cooling, even at lower speed.

Take care,

Dan

I have a ModWright Oppo 95 and I also have a very difficult time "hearing" from others that the fan is not an issue from a noise perspective. I sit approximately 9 feet from my component shelf and I can clearly hear the fan from my listening position. I've even built a baffle extension which essentially is an extended exhaust port with sound absorption material on the inside surfaces to try and reduce the db level of the fan but I still can clearly hear the fan.

I find it so odd that the fan noise can be perceived so differently by the user population when in fact Oppo claims that no revisions have been implemented on the fan unit. I would imagine that the fan would consistently produce the same noise db level on every unit and yet the large discrepancy of noise perception exists.

Very interesting ...

P.S. Dan, can you provide information regarding the addition of Bybee rails to the Oppo 95 and what results it produces?

I have been considering going with the ModWright Oppo BDP-95 but have a question.  Does anyone use this as a DAC for their computer audio?  The ports are there but have never seen a comment about using the 95 as a DAC and a player.

Post by: modwright on 13 Mar 2012, 06:58 pm
Hi, the Oppo 95 does have a USB and eSATA ports for use with an external storage device only, not direct connection to PC or laptop.  It is 24/192 asynch and I have used it and listened to it and it sounded good.  It goes to the same DACs and and of course through our tube analog stage.

The only thing to remember, is that there is no user interface for this input, so you must be connected to a TV or monitor, in order to navigate the directories.  And again, it has to be a static external drive, not through a PC or laptop.

Thanks,

Dan

I would definitely second the notion of at least partially removing the cover, mentioned by Ric.  Not only is the sound slightly better, the fan will run much less often (also remember Pure Audio mode for less fan on-time)

Re Variable Audio Output: in the past with players and DACs, the sound has been comprised by turning down the volume using the player's volume control.

Is this the case with the Oppo 95?  I'm interested in two-channel audio in Pure Power mode.

Given that the volume control is in the digital domain (I think) I would expect it to be available in Pure Audio mode.  I have also read that you don't want to be using the volume control below 85% or so or the sound will become degraded.
Title: Re: ModWright Oppo BDP-95 Mods?.....YES!
Post by: jfz on 15 Mar 2012, 04:19 pm
The volume control is definitely usable in Pure Audio.  I could have sworn I read somewhere that using it (including most of the way down) would not degrade the sound.  Does anyone know for certain?

A 'Pure Audio' mode is not for "degrading the sound".
A "PA" mode bypasses the video circuitry for a 'purer' audio (sound).
YMMV (as too the effect or even being able too perceive any effect at all)
Title: Re: ModWright Oppo BDP-95 Mods?.....YES!
Post by: rbbert on 18 Mar 2012, 01:56 pm
It's the volume control which degrades the sound, not the Pure Audio mode. :nono:
Title: Re: ModWright Oppo BDP-95 Mods?.....YES!
Post by: jfz on 19 Mar 2012, 12:29 pm
According to a long-time beta tester who posts frequently on AVS Forum, the volume control is 32 bit, and therefore does not compromise the sound if it is turned down.  I did that this weekend, and did not notice any degradation.

A caveat:  I am using a high-end preamp, and did not turn the player's volume down very low. 
Title: Re: ModWright Oppo BDP-95 Mods?.....YES!
Post by: modwright on 19 Mar 2012, 04:02 pm
You can turn volume down to a certain point, before which significant 'audio' bits are dropped.  I.e. with 16 bit signal, you can drop 16 bits before signal is affected.  With 24-bit signal, you can drop 8 bits before signal is effected.

Not sure if relationship is linear, but I doubt it as volume controls work on a log curve. I.e. not sure that 50% volume means that 16 bits are dropped.

Let your earsbeyour judge.  Certainly a 32-bit DAC makes a digital control much more feasible.

Thanks,

There is an excellent post on AVS forum in the Official BDP-93 Owners on page 659 and link 19765. Mr. Jaehong has a Phd and 30 years experience an written 4 books.

Hi, our external supply for the tube analog stage is tube rectified, linear, and has dual-discrete SS voltage regulators.  The 95 also has a linear supply for Analog and Digital supplies for audio, but I believe that the video IS still powered by an SMPS.

It COULD be done and would likely improve the video, I just don't have the time to do so right now.  If a person were to do so, I would probably use the Oppo 93 and build a supply for audio and video that was linear.

My focus is always music as I am really not a videophile and am not knowledgeable enough of the subject to claim to be able to make significant video improvements.

Thanks!

Title: A Little History Lesson...
Post by: NutBuster on 30 Mar 2012, 03:05 am
We are designing an upgrade board that will allow as many as three digital inputs to be added to existing ModWright Modified players, tube or SS, thus allowing the ModWright player to act as both player and DAC.

Digital inputs will include SPDIF (RCA and/or BNC) and AES/EBU (XLR) inputs, USB not included.  The decision to not incorporate USB was based on the fact that to do so would compromise THIS design.  You can easily use a variety of external USB/RCA converters, such as those from M2Tech, that allow for up to 24/192 hi-rez data.

Design Scope and details below:

Design scope has been finalized and expanded. Digital input design shall include custom vcxo control algorithm, data buffeting and other circuits to achieve less than ~20ps jitter levels. This is the proprietary design of Alex Dondysh, digital engineer (former owner of 3Dimension Audio).

this appraoch was chosen over merely using a standard digital input receiver with internal PLL circuit, typically producing jitter levels on the order of 200ps or more!  It DOES add cost to the design, but I feel the performance MORE than justifies the end cost.

This is not to be confused with the master clock, internal to the player. The purpose of this clocking/buffering circuitry is to minimize jitter of external digital data, feeding the player's own DAC. This is to maximize performance of the modified player as a DAC for external digital source. In this configuration, the circuit consists of our ultra-low jitter digital input circuitry to the player's own DACs and output to ModWright's own analog stage design.

Oppo BDP-83SE and Sony XA-5400ES units will be the first units available for this upgrade.

SPDIF (RCA), BNC and AES/EBU (XLR) inputs may be provided. Multiple digital inputs will be switchable via mechanical switch on back of player. Toggle switch on rear of player will toggle unit from player to DAC
The digital input will accept up to 24/192 samples.  It will accept 16/44, 24/48, 24/96 and 24/192 if available.  It will not upsample but will re-clock and buffer the data for ULTRA-LOW jitter.
The mod is in final testing and programming stage for the Sony XA-5400ES.  At this point, the digital input mod for the Oppo 95 is on hold until we have the Sony digital input mod finalized.

The Oppo WILL accept USB music input from external USB hard drive or USB stick or other storage media.  At this point, it will not allow direct connection to the Touch via RCA (SPDIF).
Agreed and appreciated.  We are completing the first digital input mods for the XA-5400ES and while it has been difficult and taken longer than expected, the results are promising!

This is also 90% of a DAC, that we will be offering in the future as a standalone product.

RE the Oppo, I agree, if Oppo has provided THIS much flexibility already, it doesn't seem difficult to incorporate the rest of the functionality into a future firmware upgrade.


Our first intent, was to use our digital input receiver, to accept XLR (AES/EBU) and Spdif (RCA) inputs and have them feed the internal Sony DAC. Well, this took over a year and in the end, I have ONE working prototype, but it is VERY twitchy and I decided to 'punt' on that approach in favor of a more attractive approach!

The problem was the interface and communication with the Sony firmware.  We decided it would make more sense for our digital input receiver to just have IT'S OWN DAC.  We chose the PCM1794, which is much better DAC than the Sony uses.  There is zero oversampling, but there is re-clocking and data buffering.

This combination formed a complete DAC that is SO GOOD that we are also using it to add a DAC to our LS 100 and KWI 200 SS integrated amp.  I have the first Sony prepped and ready for install of this new DAC/Receiver board for testing, today.

I have also been working with installing it in the Oppo 95, but bizarre grounding schemes in the Oppo have made this VERY challenging.  I am not expecting such problems with the Sony.  I know that the input receiver works in my one prototype.

More to follow as I install the first Dig. Input mod in the Sony XA-5400ES.

The truth is, it takes TIME to do proper design, and rushing a product out before it is ready is NO recipe for success!

As a result, I have 'hunkered down' in my 'lab' and worked hard to finalize the following designs:

Digital input mods: Oppo BDP-95 and Sony XA-5400ES.


First of all, the digital input mods for the Oppo and Sony have been in the works for A LONG time and proved to be a MUCH bigger task that initially anticipated.  We changed tack late last year, after realizing that it was not feasible to simply integrate our digital input receiver board into the Sony and Oppo.  As a result, we added our own DAC to the receiver, such that the digital input includes our own DAC, completely separate from and BETTER than the players own DAC, but feeding the same tube analog stage as part of our mods.

The Oppo is still giving me fits, but I AM making progress.  Specifically, it sounds great, but there are grounding issues that are not acceptable to me and I continue to analyze and approach this from different angles.

We have prototype installations of the full DAC and its own separate power supply, including USB input (24/192 asynch') in both the LS 100 and KWI 200.  We showed these prototypes at CES and they sounded very good, but were still not ready for final release.

What I am trying to say is that while there have been delays, ModWright is moving forward with many new products.  Please simply understand that quality and excellence takes time!
Well, I have actually found the solution for the Integrated and Sunday's late night efforts proved fruitful with my LS 100 proto.  I believe that I found the necessary grounding sequence to eliminate the noise artifacts.   When I left last night, the HF artifacts were gone and it was sounding VERY GOOD!

I am hoping that what I learned last night will shed light on the digital input issues for the mods.

The standalone DAC will follow the finalization of the DAC in our integrated and LS, as well as dig. Inputs for our mods.  If grounding is the key, as it appears to be, then the isolation scheme that I had planned for the design may not be necessary.  I will begin by prototyping the standalone, while I am working through these things.

To be honest, I am still struggling with a noise issue and it has been costing me sleep for a LONG time.

I shifted my focus to installing the DAC module (same digital core) into our LS 100 (very similar circuit as used in Sony and Oppo players) and learned A LOT about the necessary grounding to remove this noise.

I also did the same in the KWI 200 integrated and alleviated it.

I am today, working on the Sony, as it is exhibiting the same issues and I am taking a new approach.  I can't express how frustrating this whole endeavor has been.  If I make a breakthrough today, I will post here!  It is my focus today.

Thanks for asking and thank you again, those who are waiting, for your continued patience.

Post by: modwright on 9 May 2012, 11:10 pm
OK, another long day of working on the unit.  I said I would post my results, so here goes:

1) The use of Lundahl line-level transformers DOES serve to remove 90+% of the HF artifacts and may be an option.
2) Without the Lundahl transformers, it appears that a harmonic of the master clock frequency works its way into the analog signal.

I shortened all signal leads as long as possible and operated the units strictly as a DAC today and no matter how I ground it - i.e. already using ideal grounding scheme as learned from LS and Integrated designs, there is still an issue with the clock signal.  The master clock is actually generated from our own digital receiver board and is superior to stock and upgraded outboard clocks.

Progress was made, but a solution not found.  The line-level transformers may be used no matter what.

I will continue to post progress.

Thanks,

Dan W.

Well, today was a good day in development.  In case some of you are confused about why I am talking about the Sony mods, when this thread is about the Oppo, is that I got so frustrated with the HF noise issue in the Oppo, that I turned to the Sony to see if I could resolve it there first and carry the knowledge back to the Oppo.

Well, today actually bore fruit!

The HF noise is now low enough that it is swamped in the noise floor and I am satisfied with its eradication.  A combination of buffering and impedance matching of the clock signal and just the right grounding combination did the trick!

So, I am about 95%-98% pleased with the Sony.  I need to tidy up the first article and make sure that all functions work properly and I will be happy!

Now, I will take this knowledge TOMORROW and move onto the Oppo!

Thank you for your support and to all those who are reading this with interest.

Hi, the tube mod is the key to the mod!  The purpose of the digital input is ONLY for flexibility.  It allows the use of external digital inputs, to utilize the players tube analog stage and double as a DAC as well as a player.

The Truth mod for the Oppo, without digital input, has won HUGE praise since inception and we have MANY very happy customers.  If you are considering the mod and don't need or want the digital input, then we can do that mod immediately and you will be VERY pleased!

Title: Dig. Input Update!
Post by: modwright on 16 May 2012, 06:22 pm
Hi guys, another update as promised:

The Sony XA-5400ES:  I have managed to get rid of the HF issue, but in the process, introduced some LF power supply noise, so am looking at grounding here further.

Oppo 95: Added a dedicated 5V supply, highly regulated, totally separate from the main machine and power supply.  Updated grounding to be same as that in Sony.  Still HF issues... :cry:.  The grounding in the Oppo is UGLY, especially as it pertains to this.  The four layer analog board and every other ground is connected to the chassis.  I have everything star grounded, independant of the Oppo and no matter where I connect to the Oppo, I get the HF issue.  I am not giving up, but it is still a brick wall!

Just wanted to keep everyone up to date.

Thanks!

Thanks for the 5/16 update, Dan.  A side question: if one wants to use the current Oppo to play hi-rez files downloaded from a computer, does he send them via a USB cable to the Oppo?  And, if so, is this sound going to be significantly worse than if he has the digital input to use?  I'm sorry if this is a very elementary question. I'm confused as heck about "computer audio".

For USB input, you will have to use the stock USB input on the Oppo 95.  This can only be connected via USB and a standalone drive, but not a PC.

Our digital input board will only have RCA and AES/EBU, not USB.

i had oppo send a 95 to dan for the ss mod, and received it early last week.  after cabling for it arrived, i hooked it up and broke out a few blu-ray and super-audio disks for listening.

my understanding is that sacd is a dead format, but i was able to snap up several goodies at excellent prices:  colin davis' LSO berlioz recordings, jon leifs' Edda on BIS, and jordi savall's recording of the monteverdi 1610 vespers -- all favorite pieces.

i wasn't disappointed - these recordings sound fantastic.  more detailed, open, and rich than the rips of the cd layer.  it took a while to figure out how to set up the oppo, but once initialized to the correct settings, glorious music poured forth.

nice work dan!

I just got my MW BDP-95 with the tube mods and I am already enjoying it with a pair of RCA 6SN7 VT231s and a Mullard GZ34.  The first thing I noticed was a tighter and fuller bass and an overall more pleasing presentation of the music.

I have a question about the tube stage and power supply.  If I am watching a movie and using the 8 channel analog outputs or optical digital out can I leave the power supply off since I wouldn't be using the analog output stage?

You don't need the tube stage supply on
to watch MCHovies or use digital or HDMI
outs.

Tube supply only need be on for 2CH music.

Thanks,

Thanks Dan.

That's what I thought.  That should save tube life a bit.

What's your experience as far as how long it takes to break in the unit and settle into its long term sound?

Nice call on the tube combination Dminches!  I've had my Modwright Oppo 95 since February, though finding time these days to just sit down an listen is near impossible.  After reading your post above, and I plugged in the same tube combination since I had all of them on hand, and started streaming Pandora.  I was going to multi-task with the music in the background, but damn, it got a hold of me and dragged me right in. I spent 4 hours just enjoying my favorite Pandora stations thru the Modwright Oppo, and I was totally immersed!!  And this was only Pandora, not any of my CDs / SACDs / hi-res files!!  Call me impressed!

It's a wonderful player Dan!  Coming from the Modwright 9000ES (which I still have), I was hoping for equivalent sound, and I think Ive got it, and then some!  Well done!

I've had my OPPO BDP-95 (the $500 SS mod only) modified by Dan and can report that it is a very worthwhile investment.  I do have a question for Dan and any other BDP-95 owners:  what are some recommended power cords for this player?  I'm currently using a Granite Audio 555 which I bought some time ago on AudiogoN.  I recently came across a letter online referencing Dan's positive comments with respect to the synergy between an Audio Magic cord and the Sony 5400.  Is there perhaps a special synergy between ModWright mods and Audio Magic cables? 
Title: Re: ModWright Oppo BDP-95 Mods?.....YES!
Post by: modwright on 29 Jun 2012, 12:26 pm
First of all, power cords DO make a difference.  There are a lot out there and I can only speak for the ones that I have used and like.

Audience powerChord.
WyWires power cords.
VooDoo cables Dragon series.
Acoustic Zen and Harmonic Tech.
Millersound.

To be honest, I have been too busy lately to critically listen with all different power cords and give a huge thumbs up to one over the others.  I have not heard the Granite Audio or Audio Magic cords, although I have used many other of Jerry's (Audio Magic) products and they are great.

Hopefully others will chime in with their preferences.

Thanks,

Dan

Thanks Dan.  My experience has always been that power cords are a very important part of the system.  I've owned many pcs over the years yet have had only a few through my system since owning the OPPO.  The Stefan Audio Art Endorphin, Granite Audio 555, SoundString and SoniKleer have been hooked up to the OPPO at various times since having it modified this past winter.  I did order the Audio Magic Liquid Air yesterday.  The entry cable not the Clairvoyant. I'll report back once I've had some time to listen.

A brief update:  I've been listening to my OPPO 95 with the Audio Magic power cord as well as a couple of my other current cords.  Initially, I was drawn to what I would describe as the AM cord's analogue character:  warm yet detailed.  Maybe a bit soft. Eventually I put my Stefan Audio Art Endorphin pc (which has been one of my all time favorites) back in.  It seems to bring more verve to the music while still avoiding many of the usual digital nasties. Then back to the Audio Magic.  Then
in went my Avondale BLUE cable and I was reminded why I've like this cord so much.  A great sense of air as well as good PRAT.  I also went back into the OPPO's audio settings again.  After adjusting the crossover, trim, and distance settings I am stunned by how much more LIVE the music sounds.  When I changed settings my AM pc was on my Gallo sub and that is still where it is.  At some point I'll move it back to the OPPO with the current settings.  Even though I've tweaked the OPPO's audio settings numerous times since the original purchase and then since Dan's SS mod I've not stumbled upon a combination as successful as this.

A question and a comment.

Question: Will Oppo perform repairs on a ModWright-modded 95?  I have a 95 that I bought new in Jan 2011 that just 'died'.  For video at least - get no display other than a (distorted) Oppo logo screen.

The unit serves as one of my audio sources (the other being a Mac Mini-fed Mytek Stereo 192 DAC) as well as the family DVD spinner & Netflix streamer.

Comment: The unit will certainly be down for awhile so I just picked up a used 95 with the full MW tube mods, including a Bybee and Audio Pulse Gen module.  When I have the SS-modded 95 back I will compare the two extensively on audio.  I myself have never seen a side-by-side comparison of the SS-vs-tube mod.  I suppose it won't be exactly apples vs. apples since the tubed unit does have the other two, power-supply-related mods.

I prefer the voodoo power cords myself which i use currently.

We will certainly service the Oppo 95, for the cost of parts and min. labor.  This is a issue that would normally be covered by the Oppo warranty, but we can purchase replacement parts and PCB's from Oppo and will service all of our modified products.  I expect that replacing the video PCB is what is needed.

I believe that you will greatly prefer the sound of the tube modified unit for audio.

I agree, the VooDoo power cords are very good!

Thanks,

Dan Wright

Post by: PaulFolbrecht on 26 Jan 2013, 07:40 pm
Dan, that is great to hear.  I believe the unit is out of warranty anyway as it was bought new (& modded by you) in Jan 2011.  Anyway, even if Oppo are fine people, I'd rather have you go through it than them.

I will send it off ASAP.

In regards to the power cords, I just completed a round of comparisons with the 95 tube mod, and the 83SE with SS mods.
I added an IEC to the 83SE so the analog stage would get power from a separate cord, and PLC if necessary. But I did do some comparisons before the installation of the second inlet. The JPS Labs Kaptivator and their Digital AC cord were best out of about five cords. A silver cord and a stiff solid core copper cord were the worst. I won't mention the brands of those two. The Kaptivator also remained the best on the analog side after the second IEC install.
For the 95 with tube mods ( the mods are almost the same as the later 105 tube mods), I tried six cords on the outboard power supply, and three on the player.
On the player, I ended up with the same cord/PLC setup that is best on the 83SE : A BMI Hammerhead from player to regenerator, then a Purist Dominus Fluid to wall outlet.
For the outboard power supply w/tube regulators, the following cords are in order from best to least benefit :
1. Clarity Cable Clear Focus.
2. Sablon Audio Gran Corona (very close second). May be better with some set-ups.
3,4. Isoclean Super Focus, and Mojo Audio 8 Guage (tied but different sounding).
5. Harmonix X-DC. Good overall sound but not excellent.
6. Audio Magic Liquid Illusion. This particular cord I do not recommend for the outboard power supply. Not terrible, but it lacked harmonic richness, weight of impact, and sounded rather plain.

I have more cords here, but became very satisfied after hearing the top two above.
Hope this helps !

We do offer the region-free upgrade as part of our other mods, but not by itself.  There are many that offer this service however.

hi
i stiil need to figure out how to use modwright tube mods on the stereo analog board when using the dvd or bluray?
help please
ps can i just plug the front cables on the stereo out?
Title: Re: ModWright Oppo BDP-95 Mods?.....YES!
Post by: modwright on 25 Nov 2013, 05:30 pm
I am not sure if that is how it works or not.  As I understand it, when configured this way, the FL/FR signals are fed to the stereo outs.  I would recommend calling Oppo to verify if this is the case.

Thanks,

Dan

I read that the 6SN7 tubes are used in a differentially balanced way. What does this means?
Title: Re: ModWright Oppo BDP-95 Mods?.....YES!
Post by: modwright on 30 Dec 2013, 09:58 pm
The 6SN7 is a dual-triode tube.  Both triodes are used in each channel for a fully balanced output.  This means that the XLR outputs see a (+) and (-) signal, as well as ground.  The RCA jacks output only the (+) and ground signal.

Thanks,

Dan

Post by: Maritan on 31 Dec 2013, 12:11 am
That's interesting. I wonder how the circuit is designed?

1. Is this the same for the Oppo 105 as well?

2. If I use only RCA out, does only one of the triodes in the 6SN7 tubes get used?

3. If yes, can I swap the two 6SN7 tubes from left channel to right channel to use the previously unused triode?
Title: Re: ModWright Oppo BDP-95 Mods?.....YES!
Post by: modwright on 31 Dec 2013, 01:32 am
It is very similar to how the 105 is configured.

Actually both triodes see voltage and signal, for both tubes, all the time.  It is is simply a matter of whether you USE the signal from both triodes.

Thanks,

Dan

Post by: ricardo007 on 13 Jan 2014, 11:15 am
hello Dan
if you use RCA only then even if you actually use only one tube (meaning one tube necessary only) still both tubes are used therefore age at the same rate
is that correct?
best regards
richard
Title: Re: ModWright Oppo BDP-95 Mods?.....YES!
Post by: modwright on 13 Jan 2014, 05:49 pm
If you use RCA only, you are still using two tubes.  Both tubes and both triodes in both tubes are always being utilized.  If you listen to RCA only, then you are simply only listening to the signal from one triode per tube.

Short answer:  Both tubes age fully at the same rate.

Thanks,

Dan
