The Hugo of streaming?

Posted by: charlesphoto on 14 June 2016

Ha, knew that would get your attention!

I was using my UQ1 for streaming only purposes to the DAC V1 via a good s/pdif cable, but was never entirely happy with the set up, esp as the UQ was mostly going to waste. My budget wasn't much, and I didn't want to just move over to another streamer, esp as the asynch USB on the V1 is one of its main features, and supposedly better sounding than coax. I considered a Mac Mini, but then started reading over on the Computer Audiophile forum raves about the forthcoming Sonore microRendu. So last week I got in on the second batch and have had one up and running since Friday with an iFi power supply until I get a proper linear power supply for it (probably the upcoming Uptone LPS based on charging ultracapacitors). 

For those not in the know, the microRendu is about the size of a small flip phone, only connects ethernet in and USB out, and runs a small custom linux OS on an sd card that is accessed headless with a really simple and easy GUI. It was built with low noise hardware and the best sound throughput as the top priority. Took all of under five minutes to set up. It has several modes: Squeezelite, DLNA (regular and open home), NAA Roon/HQ player mode, airshare and I think maybe one other. I have mine running in upnp mode from my Vortexbox using the Lumin app as a controller. Currently also running Roon as a trial, but for what it costs and the hardware requirements its not for me at the moment. Cool app though, esp if you have a big collection.

From the moment I plugged the microRendu in I knew that it was game over. And it just keeps getting better as it burns in; I also added an Atlas Element USB cable that sounds really nice for the price. I think the likes of already fringe companies like Aurender and Auralic have got to be more than bit worried about what these even more fringe upstarts are doing. I'm not really the best person to be doing comparisons because I've never had the $ to change out gear like some do, or work my way up a heirarchy like Naim. But it really is extraordinarily impressive, made my old set up sound "broken" even (and I thought it sounded pretty damn good). I never thought I would have a hifi this good due to $. Lots of talk in hifi about "inky blackness" which I've never really experienced until now. Reverb esp - its like it just floats out into an empty void. A bit disconcerting at first actually! Also the balance is perfect - voices are right where they should be, piano sounds totally natural (the true test imo), nothing recesses or comes forward in any strange way. I was experiencing some fatigue before and now that's history. The only fatigue now is from staying up to late listening to music nonstop!! 

So, if you're looking at streaming options and have a dac (or plan on getting one), then you should check out the mR. Imo its' this years Hugo - a serious game changer, at least as far as where USB audio is at. For me it's all I'll ever need in that regard. And the UQ is now happy and wonderful sounding where it should be, in my basement office, utilizing all of its functions.

I got frustrated with 2.5OS DLNA mode (20.6). Jesus is looking into it, but in the meantime (rather than keep switching back to 2.2 OS) I loaded Roon trial, and RoonReady mode with 2.5 OS is working  fine so far. Nice interface too!

Posted on: 09 July 2017 by Brilliant

Jesus  got it working (and on a Sunday no less). He needed some tweaking on his side. I will be listening for the next week or so to form an opinion on 2.5 and will post here!

 Is it possible to go with a single FMC as opposed to 2 FMCs (upstream and downstream)? I am kind of short with wall outlets.

 

That's a bit like saying 'I only want either a turntable of a pair of loudspeakers.' You kind of need both!

LPS-1 Cheap Upgrade 2 >> microRendu

Having recommended a DC04 based DC power cable at a fraction of the cost of the Sonore DC4 I have found an even cheaper and better solution.
 

A $10 silver/teflon cable as recommended by a chap on another site.

http://www.ebay.co.uk/itm/1-2M...e:g:tJEAAOSwu1VW3XgI

(If in breach please remove the link)


The effect of these different cables powering the mR in my system is ridiculous. Adding the LPSUs to the REX/LEX was subtle in comparison.

I used the DC04 to make a DC-DC cable, and then used one of the Silver DC cables to make two cables, cutting it in half; you could double up the cables to make a quadstar, which I might do later.

LPS-1 Supplied cable:
Sounds detailed, great bass, mid-range lacks tone.

Canare DC04

Tone & timbre by the bucketful, but sounds slightly darker - bass heavier, high frequencies sound a bit attenuated. Still preferable to the standard cable.

Silver/Teflon Cable
Really very good. LPS-1 powered by an unmodified Teradak DC30W. This is a real step up on the SBooster, which has a captive DC cable.

My first impressions of the updated 2.5 OS:

With Roon trial (RoonReady mode) -

I like it. I am 'tuned' into the music. The sound is ever so slightly different from what I am used to with J River.  I am still getting familiarized to it. I have not compared to the 2.2 OS

With J River (DLNA mode 20.6) - I tire rather quickly, and feel like turning the volume down a bit! I think there is increased clarity in the sound stage but it is somehow offset by listening fatigue. This is a surprise and a rather surprising development.  For this reason and for the time being, I feel that I  prefer the 2.2 (DLNA mode 19.09) with J River MC22/DAC-V1 f/w 1.16. I find it more pleasant over extended periods - and quite engaging.

Have you tried LMS (Squeezelite) mode? I find it serving LMS on my Vortexbox with 2.5 to be quite good sounding. 

Plenty of updates now available - new 1.4 board update, ultraRendu, and the new isoRegen. I'm in no hurry, but  will probably choose one or more by the end of the year. 

Posted on: 11 July 2017 by charlesphoto

And check out Ghent audio for a full line of DC cables with connectors and lengths of your choice. Good stuff (Canare Quad) for not outrageous $.

Hi CP

I have no experience with mR/LMS - I do like the Ghentaudio prices that I see and may try one of their cables at some point. I am happy with my silver plated copper cables at the moment , but I am willing to try other reasonable alternatives.

Thanks.

I have a Ghentaudio cable en-route to test against my home made jobs.

I really like the music via the Squeezelite applet. Jesus updated it to the R2 version for me. If you use the C-3PO plugin in LMS you can up and down sample the music files. Unfortunately the Raspberry Pi 3 doesn't have enough grunt.

Although Jesus didn't claim it I find the 2.5 OS sounds better.

 

Q: Is anyone thinking of moving to the new 1.4 board ....or to the ultraRendu?

I find Sonore's approach much more supportive of their user base than SOtM.

I am not going to jump on the 1.4 board.  I did upgrade to 2.5OS.  Actually I am contemplating selling some of my gear to fund a speaker purchase.  

I am coming to the realization that less is more for me and my music taste.  I am finding the higher up the audio chain I am going that I am enjoying the music less.  When critically analyzing a change or "what" I am hearing I love the Sonore and my Gumby.  When stepping back to just enjoy the music these components are too resolving and my music that sounds good is less amd less. For examply I enjoy the iFi PSU better than the TP, even though the TP is smoother and more audiophile.  (One example of many I am experiencing).  

Does that make any sense?

Posted on: 12 July 2017 by Brilliant

I also find TP  on mR boring compared to the 'bouncy' iFi - however the TP 7/2  works well with the Uptone Audio USB Regen>TEAC UD-501 combo.

I have no immediate plans of upgrading the mR.

Posted on: 12 July 2017 by Hmack

I find just the opposite. For me, the TP 7/2 transformed the sound of the microRendu very much for the better. I had previously used the iFi which ultimately did not impress me at all. Strange how  our tastes can differ so much. My experience is that the sound with the TP is both smoother (for the better) and more analogue sounding rather than more 'audiophile' sounding.

I do not intend to upgrade to the 1.4 board or to the ultraRendu in the near future, largely because my main streamer/DAC is, and is likely to continue to be the Linn Klimax DS/1. However, I wonder if I can draw on your collective experience with the mR for some advice. I am afraid I haven't followed the mR forum thread for some while and so am a little out of touch? I am currently still running OS 2.2. Can you save me some time by telling me what I need to do in order to update from OS2.2 to OS 2.5, and what benefits (if any) are delivered by the update?

Any advice appreciated.

 

Posted on: 12 July 2017 by Brilliant

I do not think there is any disagreement re: TP -'..smoother (for the better) and more analogue sounding..'  Is it more engaging/exciting?

 You have to purchase the 2.5 OS ($20). Sonore sends a new micro SIM by mail! If you are using the DLNA mode my advice would be - caution, (please see my comments above)! If not - then probably worthwhile as others have noted.

Posted on: 12 July 2017 by Brilliant

^That was intended to read 'microSD' card - a link for purchase was sent by e-mail a while back.

Posted on: 12 July 2017 by Hmack

Thanks for the info, Brilliant.

I guess that at a price of around $20 I might as well buy the OS update and give it a go. If I don't like it, it should be a simple matter of slotting 2.2 back in again.

Thanks.

I find I enjoy the mR with iFi when utilizing it with my valve amp.  I prefer the TP when going into the analog input of my qute. (To be specific)

I use the MPD/DLNA interface. There are some of us having issues with this. Jesus knows about it and is working on it. I have done some serious experimentation with 2.5OS. 

 

I switched her back to 2.3. The other connections methods seem to be fine.

I have been using the Uptone Audio USPCB A>B adapter between mR & DAC-V1 over a period of three days. The familiar tracks sound to me like another micro-layer of 'hardness' in the mid to high frequencies has been banished , thus sounding even more natural when compared to my custom USB cable. Out of the box the lowest frequencies felt a bit more 'rounded'/less defined than I am used to, but got better when I switched the unit's (very tiny)  VBUS switch from 'OFF' to 'ON'.   My USB cable has no VBUS, and I am not sure why that would matter with this adapter. I will play with the switch again after a week or two of usage to double check if it really has the effect. Could it be the missing link?

Uptone claims it is 'better than any USB cable' and more:

"Carefully designed with a 4-layer circuit board, we took into account even the mass of the connectors and the widths and thicknesses of the traces. So this new adapter perfectly preserves signal integrity and impedance match."

=? , USB, 90 ohms? not specified! Physically it looks like an amateur job for finish, but the fit is good and it functions. All in all looks like  great value so far.

I am not rushing to the 1.4 or ultraRendu, as I am enjoying what I currently have and feel no immediate need to change. But I do appreciate that Sonore have made the upgrade path possible, good customer support.

Hmack, I did find the OS update worthwhile, I am using LMS.

I have been making some minor mods:

1. I find the mR is very sensitive to the DC-DC cable from the LPS-1. Most recent update is to use a silver/teflon wire in StarQuad formation with a EMI/RFI protective mesh. Cheap and good result: and
2. LT3045. These boards regulate the DC removing ripple noise. I could use these at three points in my system:
a) StarTech LEX (5V)
b) StarTech REX (required voltage too high)
c) microRendu (Now a 1A version of the board is available, so I will be installing one in a couple of weeks)

http://www.linear.com/product/LT3045

The noise floor drops another notch. The character of your system doesn't change, but details that were before almost perceived now come into clear focus. These are the sorts of changes that friends and family simply wouldn't notice, 'Your system sounds great, but it always has'; any audiophile WILL, and be very pleased.

The cable & LT3045 are DIY, buying the bits etc.

What feeds the LPS-1 can also make a difference. I am quite satisfied with my direct setup PC/mR/DAC-V1 (fixed out) that it is currently beside the vinyl TT in my main system. Quite a feat in tweaks, but it has me dancing hours on end!

Posted on: 02 September 2017 by charlesphoto

Thanks for the feedback on the 1.4 board upgrade. Planning on doing this myself soon - it sounds like the biggest bang for the buck as far as upgrading goes. Would love to get an Uptone USB hard adapter but no idea how I can hang the mR off the back of the V1 without moving it further from the wall and building some kind of Rube Goldberg contraption to keep it from sagging. Using Ghent audio cables - great value and now making all kinds of DC power cable iterations as well as ethernet and USB. 

Posted on: 02 September 2017 by Brilliant

I have not upgraded the mR, and I am not sure I will. The USPCB adapter I am testing is staying put - quite recommended!

PS - I might get the ultra later on once I get another setup going.

Posted on: 02 September 2017 by charlesphoto

Oops, somehow I misread. But from the accounts I've read, the 1.4 upgrade gets one 90% to the Ultra. 

Measured behind my V1 and might be able to get the mR (at a 90 degree twist so) behind it. How do you support yours? Mine would be hanging in the air. Did you also do the 90 degree option on the USPCB? 

Posted on: 02 September 2017 by Brilliant

When I have something that I like - I keep it. I have made many 'upgrades' in the past that just did not satisfy, so I am cautious that way. Numbers have to translate into my own personal satisfaction! If they returned the 1.3 board (which they do not)  then I would consider it.

It is an experimental setup at the moment, the  V1 is on a large TT shelf and the mR/USPCB is supported by a foam spacer . It is horizontal ( i.e. not the 90 degree option you are considering) as shown in the (poor) photo below.

LPSU & microRendu

A number of weeks ago I picked up a 2nd hand LPS-1 and chose to power it with my R-Core DC-30 running at 7.75Vdc. At this point I should have realised that something was up as the DC30 started generating a lot of heat ....BUT, I was enjoying aspects of the music making. I think the LPS-1 generates very low noise, and in combination with the StarQuad DC-DC silver cable I have never heard into the music so much. In fairness as good as this was there was a missing element of visceral grunt, this made rock a bit more of an academic experience, although interesting a tad less exciting. This was emphasised over the last couple of weeks as I have visited friends with excellent Naim setups.

Early last week Logitech Media Server hosted on a Raspberry Pi 3 with the mR using Squeezelite started playing up. I concentrated on the software, and things gradually got worse. The green light on the LPS-1 didn't waver. When I more closely inspected the hardware i noticed that the LED on the DC30 was fluctuating, and so turned it off.

I moved the DC30 upstairs to power my StarTech LEX via an LT3045 whilst I used an IFI 9v to power the LPS-1. Worked solidly, but oh dear - I really couldn't listen t my system = edge.

I replaced the IFI/LPS-1 with my SBooster. Much better, but still not offering what I had before.

I moved the IFI/LPS-1/SQ DC-DC upstairs to power my Raspberry Pi 3 hosting LMS and used the DC30 to power the mR. Now this was very interesting. Not quiet the transparency of the DC30/LPS-1, but the visceral grunt is back, in spades.

Looking forward to slotting in a 1A LT3045 between the DC30 and the mR! I might even have to get the caps changed in line with another audiophile's recommendations.
 
I find the mR incredibly sensitive to what powers it, and the DC-DC cable used.
