  1. Good evening all.


    I should have an EtherREGEN in the not to distant future and in the interim i'm looking for some advice please.


    Currently my system is as follows - Innuos Zenith SE - isoREGEN - Chord M-Scaler - Chord TT2.


    In the next week or so a dCS Network Bridge will be added in between the Zenith and M-Scaler, and this is where i need some advice. Should the ER feed the Zenith Ethernet port or sit between the Zenith Ethernet streamer port and M-Scaler?


    Thanks in  advance.

  2. This was my first proper system at the age of 16.

    • Rega Planar 2 + R100 Cartridge
    • Marantz PM350
    • KEF Chorale III

    I saved hard doing a number of Saturday jobs until it got there. I distinctly remember collecting the turntable from Billy Vee in Lewisham in around 1983. What an exciting and proud day. My Step Father thought I was completely crazy spending so much money. As I recall £185.

    I second this! I have the new ZENITH MK3, and Roon via LMS (SqueezeLite experimental) sounds noticeably better than “regular “ Roon. Not subtle.


    Not sure what’s going on, but it must be the internal RAM memory player on Innuos.


    It does have a few hiccups, tracks skipping once in a while, but works great most of the time.


    I realize that Innuos owners pool is relatively small, but I encourage everyone to try.


    I concur with the previous posters.


    I'm running the SqeezeLite option on my Zenith SE and it's a clear improvement in SQ.


    Some track skipping but well worth the minor inconvenience, and i'm sure Nuno and the team will get that sorted in time.

    Functionally, I think they are similar. Architecturally, there are 2 differences:

    1. Clocking design
      • the tX-U uses the sCLK-EX frequency synthesizer board to generate the required frequency (24 or 48MHz) for the USB controller. Further SQ comes from using a 10MHz reference clock (Ref10 or OCX10) to "discipline" the sCLK-EX board. This topology requires BNC connectors, cables, and a clock chain (reference clock > sCLK-EX). Thus, the ultra-low-phase noise OCXO clock (the Ref10/OCX10) is distant from the target circuit - i.e. the USB controller.
      • the hypothetical SE USB add-on would have an OCXO fixed frequency (I presume) oscillator chip within mm of the USB controller circuit. What it lacks in quality (phase noise specs) relative to a Ref 10, perhaps it makes up due to the adjacency. This is the $64k question!
    2. PSU design
      • the SR-4 PSU is outboard, and even with a silver cable, must traverse one XLR connector, one barrel connector, and some length of cable, all of which add impedance. The advantage here is that Paul Hynes's PSUs are world class.
      • the SE USB unit would have a builtin PSU from Sean Jacobs. Its advantage would be its direct attachment - again, a few mm - to the circuit. This should lower the impedance. But it's not a Paul Hynes. ;)

    In both cases, there are pros and cons, and tradeoffs. We won't know which sounds better until the Innuos SE USB add-on is available. Meanwhile, as someone who has the tX-U, SR-4, and Ref-10, I don't feel deprived at all!


    Good evening Austinpop,


    You mentioned a USB add-on for the SE. This is new to me so do you have any further information?





  5. The below is from the What Hi-Fi site and is tantalising!!


    It may have only just launched its Qutest DAC, but Chord plans to go big this Munich by unveiling a number of new products - with each one covering a distinct area of the brand’s portfolio, and one of which is (according to Chord) set to be a landmark product in the company's history. The curtains will be opened on the first day of the show.

    Who said?:


    "...ROON is not really aimed at audiophiles, and this is just another example of that..."


    "...I wonder why they use that as a reason to not do the volume control then.  Shenanigans I guess..."


    "...Sounds like less intelligent design for dummies to use..."


    "With all the nonsensical "features" offered in ROON which no one needs, it is hilarious to hear them suggest that a DSD capable volume control is not something they will not consider."


    Yep, that sound like a person that is totally objective in regards to Roon.

    I don’t know how best to look for support on this issue. This thread or a fresh one, so here goes anyway. 


    I have the uRendu set up for about 2 weeks and 3 times in these 2 weeks it has disappeared from the networt, not available as Roon endpoint and does not show up on the Sonicorbiter page. 


    All other endpoints RPi, Bluesound are stable. All are hard-wired Ethernet. 


    The only way way to regain connection is to power cycle. 


    First of all this is annoying but secondly I’m afraid the constant power-cycling will eventually fry the SD card. 


    Any suggestions?






    Hi John,


    I have the same issue issue with a microRendu 1.4

    No apology needed, I just was not clear on the question.


    Here are the technical advantages of the Signature Rendu SE over the ultraRendu + SPS


    1. Single box design allows close coupling of the power supply and active circuitry.  This significantly reduces the impedance of the power supply.  

    2. High quality, thick gauge aluminum and steel chassis (unit weighs over ten pounds) provides a sturdy, vibration free, environment which allows the circuitry to perform better, especially the clock, as clock phase noise is degraded by vibration.

    3. 50% more power supply capacitance than in the SPS, reducing power supply noise and impedance even further.

    4. Custom wound Mercury Magnetics EI transfomer designed specifically for this product which more effectively blocks AC line noise.

    5. A couple of other small refinements which will remain proprietary.


    Sonore makes 3 levels of Rendu products, good, better, and best.  The microRendu offers fantastic performance and was a revelation on its introduction.  The ultraRendu ups the performance of the micro, and for those who want the very best possible performance we make the Signature Rendu SE, which is currently the state of the art of what we can do in a USB source.


    The digital circuitry of the Signature Rendu SE and the ultraRendu are identical, but the performance is quite different due to the  technical differences mentioned.


    Thanks for the clarification Barrow

    Hi Paul, it's not clear to me which USB you are referring to - directly from the Zenith to the DAC or? The easy way to check if the USB cable would make a difference would be to hook in a generic cable and see how it behaves. Before considering spending money on an expensive cable, I'd recommend you to take a look at the highly acclaimed USPCB. 




    Yes USB from the Zenith to the TT.


    I use a USPCB with my microRendu already and would with an OSO REGEN if I go down that route. But obviously I need a USB cable from the Zenith to the DAC or ISO REGEN. Approx 60cm needed.

  10. Opinion sought please.


    I've recently (Thursday) added a Innuos Zenith SE (running Roon) to my set which replaces a iMac, and thus far it sounds excellent, a significant upgrade.


    I'm initially connecting the Zenith to my Chord Hugo TT DAC from its dedicated Ethernet port via a microRendu 1.4 + LPS-1 which is how it was with the iMac. However, I've read that the USB output is superior. This I tried briefly with a Chord USB SilverPlus cable and I could hear little or no difference. Is the cable not good enough or perhaps the Zenith needs more miles on the clock?


    So the question is where to go from here as it's difficult if not impossible to try all the options.


    Possible options I have in mind -



    1. upgrade to an ultraRendu
    2. as above + ISO REGEN
    3. microRendu + ISO REGEN


    1. upgrade the cable to something like a Curious USB
    2. as above + ISO REGEN

    Any thoughts or experience would be appreciated.

    Thanks Esmit for your feedback. The remote only plays up with volume so not too much of a problem to deal with.


    BUT, I now have the HD input repaired and I still have the same issue with random input switching. I have spent the last few days trying different combos. I took the Jitterbug out of the chain with no change. I switched off the ISO which seems to lessen the amount of input switching but leaves me constantly worrying when it might happen again, which it inevitably does. The input switching (and sometimes Muting) only stops when I take the IR out of the chain. Is there ANY fix for this or will I have to reluctantly have to return it???


    Hi Pete,


    I have a TT and have no issues like yours. Have you spoken to Chord as they are very helpful.

    I know I am not the youngest (48) but I am surprised how many here appear to listen to their music (and thus use Roon or any other player software) in a point and shoot, one track at a time manner.


    The only time I ever play a single track or album is when I sit down and fire up the software.  From then on, I am always manipulating the queue (adding, subtracting, moving tracks/album, etc.) but apparently many (most?) are simply playing one track at a time and thus are not put off by the new, auto destruct button... ;) 


    I must admit I also rarely use the queue much like gcoupe and tend to play album by album. Maybe I need to look at the queue facility.


    I guess that's the wonderful thing about Roon, you can use it as suits you as it's so flexible. I love it!! 

  13. Clearly down to personal preference but for me it's a good move. I could never understand why several clicks were needed to play.


    Roon has fundamentally changed the way in which I listen to music and my enjoyment in doing so. The TV now rarely goes on which says a lot!

    Awaiting firmware fixes as well as the free MQA firmware.  The one bit I found to be an issue, though infrequent, is switching bitrates. Sometimes when Roon/MacMini is sending bitstreams of one bitrate, say 44kbps w. 16 depth, and then to another song with 192/24 the dCS is not quick to respond or correctly respond.  You get around this via a delay in Roon settings of a second (1000ms).  The only other thing that was due to my system setup is that I needed to enable control flow within my smart switch (Cisco) so as not to "overrun" the Roon software buffering.  Once done, never saw an issue since.  Very rarely do I get any hiccups, and they do not seem to be due to the dCS, but more likely either macOS/Roon platform.  Usually it's either a sudden playback stop with restart or other similar anomaly.  I know it's not the source, since I can even backtrack playback and not see an issue with the NAS.  Likely as not, it's some memory buffering in software; but I've no way to trace it or otherwise troubleshoot.  Hoping by moving from MacMini to Roon's upcoming Nucleus hardware/software device, I'll not even have these very occasional issues.


    That's interesting about the MQA firmware. Is there any news on the forthcoming update that will enable direct connection to a DAC via the USB?
