PRODUCT DESCRIPTION
Introducing the Sonore Signature Series Rendu. We looked at the standard Rendu, already providing fantastic performance in many systems, and thought hard about how it might be improved, how we might lower jitter, and improve on its digital precision.  We decided the correct way to go would be to upgrade all facets of the design making incremental improvements which add up to considerable performance gains.  The power supply is upgraded both in parts quality and layout.  The big addition is the new isolated, clock/re-clock, output board.  By specification, the Ethernet input is already isolated from the noise on the network, but there is still some noise produced on the processing board.  To generate an absolutely pure clock signal, we added a separate, isolated, output board with a separately regulated power supply.  This output board holds the dual Crystek CCHD oscillators, the re-clocking circuitry, and the output drive circuitry for SPDIF and I2S.  Because the Signature Series Rendu generates clean clocks and then reclocks on the output board right before the SPDIF and I2S output jitter is lowered even further.  Additionally, a very special SPDIF driver circuitry results in a perfectly clean SPDIF waveform which allows one to get the best out of any SPDIF input DAC.  While the original Rendu has set the Ethernet to SPDIF and I2S standard up to now, the new Signature Series Rendu takes performance to the next level, this is the best SPDIF and I2S we can make, and we suspect that you will think so as well.

Hi Jesus,

A couple of questions:
Does this run LMS so it is in fact a super duper Touch type product?  If so, does it pass along or get Rhapsody, Spotify, Pandora or am I confused on how the product works?
When will the price be set?

It looks like a fantastic product,
Bill

The Rendu project does not run LMS. The original Rendu and the new Signature Series Rendu are both built from the ground up to be audiophile products. The Rendu series is meant to work with DLNA/UPNP servers and controller for the playback of PCM and DSD content....it's simply a renderer. I'm aware of a way to stream those internet pay services to a renderer, but it's still be looked into. There is a way to stream free internet radio with custom playlist, but it's an advanced feature. The price will be set this weekend.

Hi Jesus,
Could you can explain to me what Roundy different from computer?
It does not use any software players? Then how does it work?
You say that this device has a high-quality linear power supplies and regulators. It has no internal impulse voltage converting? All CPU voltage using only linear regulatots?

The is not an off the self computer motherboard. Instead it's a purpose build audio board with a high performance isolated digital output daughter card. Files are streamed directly to it via a DLNA/UPNP server such as a NAS or computer on your home network. You then use your mobile device or a computer as the controller...

I have a bit of confusion over this two statements:
Supports DSD/DoP pass through via SPDIF output
Supports native DSD playback up to DSD128 via LVDS i2s output 

So does this mean that it can put out DSD on both? 

Somewhat related question.   My current DAC only accepts up to 24/96 PCM on the SPDIF input.   Is there some way to transcode native DSD files and PCM files over 24/96 to 24/96 PCM?

If you use JRiver you can tell it for files over a certain sampling frequency (e.g. DSD) to play them back at 24/88.2 for example.  The files can also be converted.

Thanks

Josh:  The SSR will pass DSD files, encoded as DoP, through its SPDIF output.  There are a few DSD DACs out there which do accept DoP (DSD encoded in PCM container, this is still native DSD, not converted to PCM) through their SPDIF inputs, but yours is not one of these (requires PCM 176.4 for one thing, is your DAC even DSD capable?).  This will only work for DSD 64 files, as higher rates would require PCM 352.8 rates, not typically available via SPDIF.

The SSR will also pass native DSD through its I2S output, for DACs like the Wyred 4 Sound, and PS Audio DirectStream, which have the appropriate I2S input and DSD capability.  The I2S output is capable of DSD 64 and DSD 128 rates.

That explains it.  I am not privy to all this hi-res stuff.

Jesus,
Read the nice review on Computer Audiophile and wanted to ask a silly question or two.  The SPDIF output, being 75 ohm cable, doesn't create a galvanic isolation, correct?  Also, is it possible or worth using a cable with BNC connection on one end for connection to the Signature Rendu and the other end being a RCA for a DAC connection that does have USB or RCA like my DAC2 HGC?  I am still trying to understand the advantages of SPDIF versus USB for high quality signal transmission.  Thanks.

Best Regards,

Thanks. It complies with the SPDIF 75 ohm spec where as a RCA connector would not. However, you can use a custom cable or an adapter. Cardas makes the custom cable for us as needed. The advantage of SPDIF is that it just works with nothing special needed such as setup and drivers...

Update:  The SSR now supports Tidal on the Kazoo (IOS) control point, too.   Pick Tidal at the set up menu and log in using your credentials for Tidal.  The playback is only Tidal catalog choices, not user defined favorites (for now), but the interface is nice.

The SSR has changed how I look at computer audio.  That is evident in my review of the Directstream on CA.

There is a prerequisite for this to work. You need to install BubbleUPNP Server on your NAS or computer to turn the Rendu into an OpenHome Renderer.

Hey Igor,

I was reading through the thread and noticed that Jesus did not really answer your question completely, and I think it is time that we really got down to the details on what makes the SSR so special:

Indeed, there are no consumer computer boards in the SSR.  The Ethernet processing board is a purpose built for high end audio product designed only to recieve and convert the Ethernet data stream into an I2S signal.  This board (and the entire SSR) has no switching regulators, only linear regulators are used, and it is designed to be as low noise as possible with no compromises made for cost saving (as would be the case with commercial computer/processing devices).  Additionally, the main regulator for this board is an ultra low noise and low impedance discrete linear regulator.
Even though the Ethernet processing board is designed to be as low noise as possible, it of course still has a high speed digital proccessor, and this processor does make some RF noise.  Hence, we developed the isolated clock/re-clock board as described in the first post of this thread.  The clock/re-clock board has 4 uV (that is microvolts of noise folks, not millivolts) onboard linear regulators, and provides the masterclock back to the Ethernet processing board, through isolation.  Then the I2S and SPDIF outputs are re-clocked directly in the clean environment of the clock/re-clock board right before output.

So far, anyone who has experienced the SSR has determined that it is at the very least equal to any digital source they have ever heard, and better than most.  Anyone interested in an Ethernet Renderer with the absolute highest level of performance needs to consider the SSR, and should also go read Ted Brady's review of the PS Audio DS DAC (at Computeraudiophile.com), where Ted found that the SSR elevated the DS DAC to a much higher level of performance.

JoshK

Ok, you'll have to excuse the newbie questions, but I still am not 100% sure how to set everything up.   I've had the SSR for a while and still haven't got it running as I was confused what to do. 

I have the SSR.  I have a NAS.   I also have an older vortexbox appliance, but I plan to migrate all the data from the VBA to the NAS and probably retire the VBA.  I did buy JRiver on my laptop, but I'd prefer to use my Ipad for playback control.   I have PCM and DSD files (recently bought a directstream dac). 

So does the JRiver software need to be put onto the NAS? Or do I have to use my laptop running JRiver to play back?  Is there anyway to use my Ipad for controller?   I am not exactly non-technical but what I am not seeing is the big picture setup of how it all works together. 

One of my buddies who is an IT guy is coming over Saturday morning to help me sort out all my networking and setup issues, so I am going to have him configure everything but I just want to know the best way to do it.

Downstairs in my HT room, I have an Oppo 105 that I was thinking of using to stream in this system, or else I'll pull out my squeezebox and use LMS somewhere.   But I think the Oppo can read data off the NAS. 

TIA,
Josh

Josh, one step at a time.  You bought the Rendu to stream, so I will address that (not your other playback devices like Oppo or Squeezebox).

Your Rendu needs to see a server with music on it.  That can be:
1) a pc/laptop with JRIver running on it, pointing to the NAS for music files.  In this case you make JRIver a DLNA server, and the Rendu sees it.
2) a pc/laptop with Minimserver running on it, pointing to the NAS for music files.  Minimserver is then seen by the Rendu via ethernet.
3) my recommended setup (if your NAS can support it) is to use Minimserver installed directly on your NAS.  Synology and a couple other NAS manufacturers support Minimserver.  Your laptop is NOT involved and therefore does not need to be powered on nor running any server..

Use your ipad to browse your music collection.  If you use JRiver as your DLNA server then use JRemote.  If you use Minimserver (either on your pc or NAS) then use a UPnP app to browse your music, like Kinsky.  However, much better is to use the improved OpenHome apps like Linn's Kazoo for your browsing remote control (or Lumin, etc).  To do this, you have to make the Rendu look like an OpenHome renderer....so install the free BubbleServer on your NAS, too and in its setup create a copy if the Rendu for OpenHome.

OpenHome allows better playlist management (playlists stay with the Rendu, not the ipad app) and better overall browsing. 

The best connection is to use a good HDMI cable and connect the Rendu to the Directstrem via I2S (both units use an HDMi connector).  Using I2S you do not need to set Minimserver to do DoP cuz I2S will accept raw direct DSD (like using ASIO).

Your laptop is NOT involved and therefore does not need to be powered on nor running any server..
With the exception that you will want Minimwatch on that laptop as it makes using Minimserver much easier.
