marksas3 Posted September 1, 2016 Share Posted September 1, 2016 Recently just changed and upgraded gear in my main listening room, actually a dual purpose 5.1 / 2ch living room. On my old system i was streaming Tidal to a Chromecast Audio using BubbleUPnP on an Android tablet, or Sonos Connect as well, either through the Tidal app or Bubble. I found the Chromecast to be slightly better sounding than the Sonos actually. All sources were running through a Marantz AVR. Still not satisfied however, I decided for my 2 channel listening I wanted to get an integrated amp to implement within the main system using the same speakers, so I grabbed a good deal on a used Peachtree Audio Nova (the original version) that has an HT Bypass feature so i can hook up all my music sources to it while still using the AVR for movies and TV. The Peachtree sounds great with my Tekton Lore Reference speakers, very happy so far (the Lore's are still in the break in period) I decided to then try the MicroRendu and Roon thinking this would be the 'next step' in audio bliss, however, i'm not convinced yet that it is any better than just streaming Tidal directly over Wifi to the Sonos or Chromecast. I thought I would hear an immediate improvement or difference but i really have not yet. So at this point i'm looking for suggestions on how i can maximize this device within my system. I'm not sure i can run HQPlayer because this is an all purpose computer that wifey uses mainly, but would like to try it if possible. Here is how the uRendu is set up: 2015 MacMini>Roon>Airport Extreme>BJC Cat6a (about 40-50')>MicroRendu (w/iFi Power)>WireWorld Starlight 7 USB>Peachtree Audio Nova>BJC 10awg>Tekton Lore Reference I mainly use Tidal but also have a bunch of ALAC files in iTunes on an external drive connected to the MacMini. Any help would be greatly appreciated. Link to comment
Cebolla Posted September 2, 2016 Share Posted September 2, 2016 You've actually got a direct comparison with the microRendu and the way Chromecast Audio streams and plays Tidal music files using the BubbleUPnP Android app. The microRendu can be used as a UPnP/DLNA renderer, so can also be controlled by the UPnP/DLNA supporting BubbleUPnP app and be used to play Tidal files in exactly the same way as you've done with the CCA. Have you tried the microRendu in DLNA Output (#3a) mode and compared how your system sounds with the microRendu in that mode, not only with the CCA, but with the microRendu in RoonReady Output (#5) mode? We are far more united and have far more in common with each other than things that divide us. -- Jo Cox Link to comment

Have you tried the microRendu in DLNA Output (#3a) mode and compared how your system sounds with the microRendu in that mode, not only with the CCA, but with the microRendu in RoonReady Output (#5) mode? I think if i only use the Bubble app and switch the 'renderer' within the app, i.e. from the MicroRendu to the CCA, i would think the music would stop, making it slightly more difficult to compare the two. However, if i open the Tidal app and the Bubble app at the same time, stream to the CCA using Tidal app and stream to the microrendu using Tidal within the Bubble app and then use the Peachtree remote to switch inputs on the fly, the music is continuous and i should be able to compare apples to apples so to speak. Should there be any difference at all whether streaming from the Tidal app or the Bubble app if both are using the same renderer? I would tend to think not. Having said that, Roon is basically just doing the same thing as Bubble or Tidal and sending the audio directly from the Tidal servers to the endpoint correct? So why then is Roon being touted as a better option for streaming, is more to do with HQPlayer integration or simply the design and interface of the software? Link to comment
Cebolla Posted September 2, 2016 Share Posted September 2, 2016 Should there be any difference at all whether streaming from the Tidal app or the Bubble app if both are using the same renderer? I would tend to think not.Most likely, not. I would certainly be inclined to trust the BubbleUPnP Android app to be providing the UPnP & Chromecast renderers with the FLAC files unaltered from the the Tidal servers, simply because its developer makes no secret of it. Not quite so sure about the Tidal app with the Chromecast, as I've never seen it officially confirmed. A big clue, ironically perhaps, is the lack of gapless support. The CCA doesn't support gapless playback natively, so when it streams separate file tracks one after the other, you will get the tell tale sign of a pause in the music when it's not supposed to be there (eg Dark Side of the Moon, etc). If the Chromecast supporting app 'fixes' the Chromecast's gapless support, then it will be manipulating the music files to 'stitch' them together, before they are actually streamed to the CCA and who knows what else it's doing to the original files. Having said that, Roon is basically just doing the same thing as Bubble or Tidal and sending the audio directly from the Tidal servers to the endpoint correct?The UPnP/DLNA renderers & the Chromecast audio devices, will be decoding and playing the music files streamed from the Tidal servers, when controlled with the BubbleUPnP. Simlarly, Roon may well be obtaining the music files from the Tidal servers. However, Roon is certainly not getting the microRendu to stream and play the music files when you are using it in RoonReady Output mode, ie, as a Roon EndPoint. It is the RoonServer itself that'll streaming and playing the FLAC files from Tidal, with the resulting PCM digital audio signal being sent over the network, via its proprietary RAAT (Roon Advanced Audio Transport) protocol, to the Roon Endpoint. The microRendu as a Roon EndPoint is the receiving end of the network being used as a conduit for the 'live' digital audio signal (produced by RoonServer playing a music file) before it gets passed to the DAC. So the microRendu in RoonReady Output mode won't be handling any actual music files being streamed from the Tidal servers, unlike when it's in DLNA Output mode. Question: is the sound produced by your system 'better' when RoonServer is playing the Tidal files (ie, with microRendu in RoonReady output mode), or when the microRendu is playing them (ie, in DLNA output mode)? We are far more united and have far more in common with each other than things that divide us. -- Jo Cox Link to comment

I have not tested it this way extensively yet, again I would imagine that the music might stop while switching from one mode to another so one would have to rely more on memory, unless the difference is night and day, which I don't think it is Link to comment

Hi, i've only heard Peachtree stuff a couple of times & not under the best circumstances. And, I am entirely unfamiliar with your speakers. Given my experience with the Peachtree, I would suggest that some of it could be due to downstream components. But as far as the microRendu; the first thing I would recommend is ditching that iFi PSU in favor of a good PSU. And, if you're using the USB input on the PeachTree, I suggest trying an USB to SPDIF converter like Singxer F-1, or DIYINC pro4a. IMO, hardware is still very, very, important. cheers Link to comment

I've read people using 'Lab' grade PSU's but i don't really want or have room for lab equipment in my living room. I think the USB to SPDIF might be a good idea, i did see someone on this forum using one, i'll look into it. Link to comment

The new LPS-1 (that is not out yet), needs a "feeder" power supply. It will be a two box unit. Cheers, Link to comment
marksas3 Posted September 3, 2016 Author Share Posted September 3, 2016 Ah ok that's what I thought, I was confused by your previous reply. Link to comment
vortecjr Posted September 4, 2016 Share Posted September 4, 2016 I think you will find that some of the early Peachtree gear used adaptive USB type interfaces as opposed to asynchronous USB type interfaces. If this is the case you really are better off going with a good asynchronous USB to SPDIF converter. I would venture to say that you will also be surprised how good that can sound into your Marantz. Anyway, I would consider this first before looking at power supply options. You can check if the Nova used an adaptive USB interfaces in Apps / DAC Diagnostics.

davide256 Posted September 4, 2016 Share Posted September 4, 2016 The simplest low cost improvements are 1) a quality PSU; I feed mine using an HDPlex supply (~$400) 2) fiber optic 100m or 1000m Ethernet between switch and mRendu ($160 for 2 - media converters, 1-optic cable and 2 -0.75m Audioquest Pearl Ethernet cables) other improvements get messier and more costly.

Media converters come in multi mode and single mode but for home use multi mode is fine ( no 500m+ runs) you just need both ends to be same. You also need to make sure whether your switch/ router has FE or GigE ports and order the appropriate speed media converter. The mRendu supports Gige/Fe so should work with either speed converter Electrically Isolate Your Networked Audio | AudioStream Regards, Dave Audio system Link to comment

I'll see what difference this makes first, then I'll decide to either upgrade the PSU or go with an SPDIF converter. I see a guy on Audiogon is selling some new Bel Canto units, I may try one of those or the Singxer F1 units mentioned above. Also not mentioned so far, this is what i'm using for power conditioning, the Furman PST-8D SMP, it is plugged into a dedicated 20A circuit. Link to comment
marksas3 Posted September 12, 2016 Author Share Posted September 12, 2016 Ok, i've got the TeraDak power supply on order, I still need to install the media converters and fiber optic but will be doing so soon. I will post my impressions after I get some good listening time in. Btw, I also have a Micromega MyDAC not being used so i may try that out with the Rendu and run RCA's to the Peachtree to bypass it's internal DAC and see if that changes things for better or worse.

marksas3 Posted October 4, 2016 Author Share Posted October 4, 2016 Just thought i'd give an update with the changes that i made to my system. 1) I am now using the Teradak power supply rather than the iFi 2) Swapped out the long ethernet run for two FMC's and fiber patch cable as noted above 3) Running the Microrendu into a Micromega MyDac rather than the internal DAC of the Peachtree Nova 4) Between the Microrendu and DAC i am testing the combination of an Audioquest Jitterbug and supplied USB hard adapter versus the Wireworld Starlight 7 cable At the moment with all of the changes implemented above I am pleased to say that i am very happy to say the least. Not sure what was the bigger difference, the fiber network or switching DAC's, but either way the sound is very clean, detailed etc etc, i could go on. Thanks for all the advice everyone.
