    Sonore Signature Series Rendu Review

    1-Pixel.png

    I’ve been using the Signature Series Rendu for several months in combination with several audio system components. Whether I’ve connected the “SSR” straight to a DAC or to an integrated amp with built-in DAC, the results have been the same, steady and superb. The performance of the Signature Series Rendu has enabled my other components to really shine because they are receiving a very clean and I assume low jitter signal from the SSR. Not only this, but the SSR turns all my components into network capable DLNA devices. Superb sound and expanding the capability of one’s favorite components are what the Signature Series Rendu is all about. The SSR isn’t a jack of all trades, rather it’s a purpose-built Ethernet to S/PDIF or I2S converter. In other words a DLNA renderer built for a single purpose and built to accomplish its job as well as possible. Members of the CA Community looking for a way to use their favorite DAC or integrated as a network / DLNA device must consider the Sonore Signature Series Rendu as it has enabled the sound of my audio system to soar as high or higher than any component I’ve heard previously. [PRBREAK][/PRBREAK]

     

     

    What Is It?

     

    The Sonore Signature Series Rendu is a simple, yet very well engineered, device that converts an Ethernet signal into either S/PDIF (BNC) or I2S (HDMI). There is no wireless, no USB, no digital to analog conversion, no AES/EBU, no AirPlay, and no streaming service support with the Signature Series Rendu. The SSR is also known as a DLNA renderer to those learned in the world of UPnP/DLNA.

     

    I see at least three very solid use cases for the Signature Series Rendu.

     

    1. Users who don’t want traditional computers in their listening rooms.

    2. Users who want to add network / DLNA capability to existing systems without replacing other components.

    3. Users who have components that already support Ethernet / DLNA but want better performance than the native component interface provides.

     

     

     

    Users who don’t want traditional computers in their listening rooms will likely prefer a component such as the Signature Series Rendu due to its similarities with traditional audio components. It’s fanless, linear power, metal chassis design looks very nice next to many other components and wont’ pollute the room or the electrical system with noise. A typical system in this scenario would have a NAS or NAS-like computer, running DLNA server software, sitting elsewhere in the user’s house. The NAS would simply serve audio to the Signature Series Rendu via standard Ethernet or even power line networking.

     

     

    Users who want to add network / DLNA capability to existing systems without replacing other components are the largest group of potential users in my estimation, followed closely by the group in the next paragraph. When using my reference system I fall into this category. I use the Berkeley Audio Design Alpha DAC RS DAC. This DAC doesn’t include an Ethernet interface, or even USB interface for that matter. It’s the best DAC I’ve heard and there is no way I’m going to replace it just to get a unit that supports Ethernet / DLNA. It makes no sense to me to get a lesser quality DAC just because I want network capability. Thus, the Sonore Signature Series Rendu comes into play perfectly.

     

     

    Users who have components that already support Ethernet / DLNA but want better performance than the native component interface provides are the second largest group of potential users of the Signature Series Rendu. By better performance I mean both sonically and functionally. When discussing DLNA I always like to call it the most non-standard standard. What I mean is that there are literally billions of DLNA devices on the planet yet most have a difficult time communicating with each other when it comes to non-trivial tasks like gapless playback. Members of the Computer Audiophile Community know full well that DLNA devices can have many issues, as evidenced by the frustrated PS Audio Bridge users. At the same time, it’s not simple to build a DLNA renderer / high end audio component. That’s where Sonore steps in with the Signature Series Rendu. The SSR is pretty much application agnostic, meaning that its users can control playback with any number of DLNA control points. I prefer using JRiver Media Center with the JRemote iOS application. This combo works terrifically with the SSR. In addition to users seeking better functionality with their existing DLNA capable components, users can also add the Signature Series Rendu in an effort to increase sonic performance. A good example of this is Ted Brady’s review of the PS Audio DirectStream DAC. Ted squeezed the best sonics out of the DirectStream by connecting a Signature Series Rendu to the unit via I2S. Ted reported that this increased performance sonically over the standard built-in interfaces.

    My SSR Experience In A Couple Systems

     

     

    System One: My Reference

     

    Berkeley Audio Design Alpha DAC RS > Pass Labs XA160.5 monoblocks > TAD CR1 Loudspeakers.

     

    I added the Sonore Signature Series Rendu to this system by connecting its S/PDIF BNC output to the Alpha DAC RS S/PDIF BNC input. I used a CAPS v4 Cortes running JRiver Media Center as the DLNA server feeding the SSR over Ethernet and JRemote as the control interface on my iPad. The sound of this system as a whole was pure joy. I don’t have playlists long enough to support my listening habits when this system is in use. For example, John Martyn’s Some People Are Crazy track from his Grace & Danger album is just so smooth and has just such a good clear baseline that I couldn’t stop listening. The Sonore Signature Series Rendu enabled me to hear something on Sonny Rollins album Way Out West that I hadn’t previously heard in all my listening sessions with this album. During the second track, Solitude, I was able to hear some squeaking reminiscent of John Bonham’s foot pedal squeaking in Since I’ve Been Loving You from Led Zeppelin III. granted what I heard on the Solitude track wasn’t near as loud as Bonham’s un-oiled pedal, but now that I know a squeak exists I can’t not hear it. I like to hear all the warts and irregularities of recordings and I attribute this latest revealing to the Sonore Signature Series Rendu. In my reference system the Sonore Signature Series Rendu is as good or better than any server I’ve used previously. There’s definitely something to be said for linear power supplies, getting the right engineers involved, and a solid 75 Ohm S/PDIF BNC connection.

     

     

     

     

    System Two: Devialet

     

    Devialet 400 monoblocks > TAD CR1 Loudspeakers

     

    I added the Sonore Signature Series Rendu to this system not necessarily to improve sound quality, but to add DLNA capability to an already very advanced audio component. The Devialet 400 monoblocks feature an Ethernet input, however this input only supports Devialet’s proprietary AIR streaming method. Using this method I was able to configure applications to output through the Devialet AIR virtual device, i.e. JRiver Media Center and TIDAL HiFi, but I was unable to take advantage of any other DLNA software. Thus, I connected the SSR to the Devialet’s digital 2 input and I was soon streaming flawlessly to a DLNA renderer / Devialet system. Functionality of the Sonore / Devialet system was terrific. Sonically I can’t say I heard an improvement over the built-in Ethernet Devialet AIR streaming method, but that’s not why I connected the SSR in the first place. Adding DLNA capability where none previously existed is what this exercise was all about. That said, sonically the Devialet monoblocks with the Signature Series Rendu were superb.

     

    Note: Readers looking to save money in this type of scenario may consider the SOtM sMS-100 Mini Server that features Ethernet input and USB output. This little server would have functioned fine with the Devialet’s USB input, but wouldn’t have worked at all with Berkeley Audio Design Alpha DAC RS because it lacks a USB input. I was unable to directly compare the sonic differences of using this low cost Mini Server versus the Signature Series Rendu. The two have opposite design approaches, but would make an interesting comparison in the appropriate system.

     

     

     

     

     

    Conclusion

     

    cash-logo-black-thumb.jpgThe Sonore Signature Series Rendu is a purpose-built DLNA renderer. That’s it. What it does, it does very well. Both sonics and functionality on the SSR were terrific. During my several months of use I didn’t experience a single issue related to the DLNA capability of the Signature Series Rendu. That’s much more than can be said for most DLNA devices I’ve used previously. This thing is designed to be a renderer, and a stellar one at that. The possibility of firmware updates exists with the SSR, but none were released during my months-long review period. The Signature Series Rendu is perfect for users seeking to 1) Exclude a traditional computer from their listening rooms, 2) Augment a non-networked system with DLNA capability, or 3) Improve functionality or sonic quality of an existing network enabled component. Sonically the Signature Series Rendu is as good or better than the best sources I’ve heard, including my reference music server the Aurender W20, SOtM servers, all the CAPS servers, and the Auralic Aries. Thus, the SSR is C.A.S.H. Listed without question.

    David, yes the Minimserver/SSR/DAC combo, when used with I2S, is as good as I've heard. Is it better than an all-out assault on WS2012/AO/Jplay with JCAT card, etc etc? No. That setup is amazing, too...but a lot more work (but more flexible with USB as an output and all the Jplay and AO tweaks available). The SSR's SPDIF is no slouch but is not quite to the level of I2S in my system. YMMV. But all of this is very very high end musically. You'll be happy with any of these results.

     

    Ted -- I posted this on the minimserver support page last nite, and am waiting for Simon to respond. Hopefully, he's soaking up the spring weather. In the meantime, I know you've installed minimserver on your Synology. If there's something obvious I'm doing wrong, perhaps you could pass it along. Im not sure why installing Java on the Synology has to be so convoluted, but it is what it is, I guess. Thanks. -- David

     

     

     

    Hi --I have a Synology DS 413J server and am trying to follow the procedure for ARM v5. I downloaded the code that seemed close to the names ending in tar.gz. There were no exact matches with the one mentioned in the tutorial. There were actually 2 that had linux and armv5 in the names and I tried them both.

     

    The tutorial says to put tar.gz file unpacked in the shared public folder. There are 6 of these on my NAS. I copied them to all, unextracted. When I try to install the Java SE embedded v 8 I wind up with the error message that the "Java Binary bundle not found. tially cover the legal aspect because files hosted on Oracle's server are protected by a session cookie requiring a Javascript enabled browser." It looks like a typo with tially but that's what it says.

     

    I'm using Chrome. I made sure the files were renamed with tar.gz as the instructions say. I'm stumped. Any guidance will be gratefully appreciated. -- David

    Ted --- I wanted to thank you for suggesting JPlay Streamer. As you know, I began by asking about the Sonore, so this was something I just lucked into. With Simon's help, I got past the java install issues on the Synology, and now have minimserver up and running on it, feeding the Zuma/jplay streamer, controlled by Bubbleupnp. This combo is miles ahead of JRiver acting as server/renderer/control point. Simon, Marcin and Josef really have pushed the envelope on computer audio software!

     

    I will certainly try the Sonore at some point, but the bar has been raised -- it will be very interesting. For those going the jplay streamer route, there are some minor things that I discovered. Mainly, it won't do AIFF files -- you have to convert them to wav. Also the pause and track search features (regardless of control point used) don't work. Josef said they will likely address the pause issue on the next version; less certain about track search (I mean where you advance or back up the music in any given track). Hit "pause" and it stops -- you're back at zero. Search is just ignored. None of this is a showstopper for me -- the sound is just so heavenly.

     

    Anyway, thanks for turning me on to jplay streamer. -- David

    I'm trying to understand the relative merits of HQPlayer NAA vs UPnP. The Sonore Signature Rendu looks like a very nicely engineered device, but it's strictly UPnP ... so no chance of using it with HQPlayer, is that right? It's very different than something like an SMS-100. Please let me know if I'm wrong about this.

     

    I guess I'm trying to decide which architecture is better and why.

    We are developing a new application for the Sonicorbiter operating system that will facilitate using Roon Server with the Sonore Signature Series Rendu and other DLNA/UPNP devices. Why...because Roon Server currently doesn't support DLNA/UPNP devices. Testing of the new application is in beta form and working nicely here.
