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.

Just goes to show there's lots to be discovered and everybody's system is different. The nice thing about most of this stuff (i.e. Uptone, Sonore, etc) is that it doesn't involve an extra zero(s) on the price tag in order to get amazing sound.

Now, if Uptone made their USB adapter with a micro plug for my Hugo, I might be persuaded to have a go.

Just been on the CA forum and this is apparently in the pipeline. Didn't even have to ask. Excellent news !

ha! i wrote Uptone earlier today to ask this very question -- for i, three days after receiving the A to B model, just bought a Hugo 2...

(hangs hifi-addicted head in shame.)

(i'm really excited to hear what the Hugo 2 brings to the party vis a vis my current 2Qute!)

I bought the Uptone Audio ISO Regen (it comes with the USPCB adapter)! I wanted to use it with a TEAC DAC in another setup!  It seemed to be working okay. However when I switched to another input on the DAC, I had trouble switching back to USB as the DAC would not handshake successfully. Cycling the power to the IR or plug/unplug the USB cable would fix this, but obviously inconvenient.I sought help with this at CA but no resolution yet. The IR is well received there and  a lot of info on it's design and benefits (it's an improved USB Regen - better low noise regulators, better lower noise clock oscillator and USB hub chip, plus galvanic isolation...)

So what else to do but move it to the mR/DAC-V1 setup! Wow! This is what I posted at CA;

"I moved the ISO Regen to another setup that uses the mR and a different DAC (NAIM DAC-V1). There are no switching issues (mentioned above)  in this setup,  and IR benefits are more apparent. I moved the LPS-1 to the IR.

PC/PPA V2 USB (LPS powered)>Anker USB/Ethernet>mR (LPS powered)>USPCB>IR (LPS-1 powered)>USPCB>DAC

This setup has improved the perceived bass response (detail & extension). It is also apparent that there is much less digital edge/hardness/glare remaining if any. Good & thanks to Uptone/Sonore!"

Thanks for all the feedback/suggestions chaps. 

If I do try a Far East LPS it may well be the Zero-Zone as it certainly appeared the most robust in my search and confirmed as such on the CA thread. But I am wavering, as like Charles my Naim gear is on a separate spur with any SMPSs on the main house ring, so there may be little benefit.

But my main aim in all this, apart from acheiving good SQ, is to also try and keep things simple, which is what led me to the microRendu in the first place - replacing a SB Touch and Regen with one small box. Lots of dangly bits in the USB chain is not really where I want to go. So although as Mr U has found there are gains to be had, I just cant see myself going down that hole. Thanks, but he USB Chain Topic thread scared the hell out of me.

I think I will be content for the moment to enjoy the improvments the 1.4 board has brought, knowing that should the itch strike, there are areas to explore.

Now, if Uptone made their USB adapter with a micro plug for my Hugo, I might be persuaded to have a go.

I bought the Zerozone SUPER-PSU 30VA DC9V 2.7A from the Far East seller  sn... (he answered my emails the fastest!)

I have been trying it out on the Ultracap LPS-1  powering the new ISO Regen in my setup! It works well, but it has to have a short DC cable, IMO. I find a 1 ft silver plated  18 awg copper of the wire I usually use to be okay. The same cable at double that length - NO.

PS - I do not have a dedicated spur for audio, so if you have one - YMMV when trying to sub the Mean Well for a LPS!

Posted on: 23 September 2017 by Brilliant

I believe that in my setup the ISO Regen USB shell is best grounded (I am using the DAC-V1 signal ground). This prevents any static charge build up which can interfere with its performance (or perhaps even damage it?). There is more info on how to do this in the CA forums.

Posted on: 26 September 2017 by Brilliant

Updated DAC-V1/PC hookup utilizing the Sonore and Uptone Audio magical units mentioned above - nice!

I am using the Rev 2.2 f/w DLNA mode with the mR. Thanks to all the input here and at CA!

Brill - you have been busy. Good to know that the Zerozone is working as expected and that you are getting good results from the IR. 

So now all that's needed is either the 1.4 board upgrade or UltraRendu to let us know it the IR becomes redundant , which I really hope it would. As mentioned above I don't want to be tempted by more boxes in the chain. 

Posted on: 29 September 2017 by Brilliant

It has been fun and a long road to 'digital' goodness, but I believe I am getting there. It might be a while before I set up a new PC system, but I do hope to plan it around the uRendu.

I have been loosely following this thread with interest, wondering if thw microrendu with a directly linked server (maybe RPi based) might be the way to go to improve on my Mac Mini/Audirvana store/renderer when my frustration with Audirvana's library handling gets the better of me, or MM reaches end of life. Otherwise I had thought Melco, Innuos Zenith, Aurender or possibly Uniti Core.

So, has anyone compared their microRendu setup with one of these alternative store/renderer solutions, and if so how do they compare (and through what system)?

And as another point of reference, for those running through nDAC, has anyone compared with NDS?

I have not tried the microRendu but I am testing a Raspberry Pi + Allo DigiOne hat into the Naim DAC and it sounds pretty good to me. I am running MinimServer and upmpdcli on the RPi. This gives me perfect handling of music libraries and metadata with just one small box and a small power supply.

I believe some folks on the Roon or Devialer forums use the RPi + DigiOne as an alternative to the microRendu.

I have been looking a little bit into Melco, IZ, Aurender and also into new USB to SPDIF interfaces (Shiit Eitr, Mutec MC-3+ Smart Clock USB, etc.) but I do not want to spend too much time in testing and I have found very little serious comparisons and reviews of these devices.

What I find very nice of the Raspberry Pi platform (in contrast to Mac Mini, NUC, etc.) is the fact that one can easily backup images of the whole system. This opens up the possibility of sharing and testing different setups by just swapping micro SD cards.

Hi NBPF,

If by 'these devices' you mean - Shiit Eitr, Mutec MC-3+ Smart Clock USB, etc.,

In the first post he links to historic threads where he & others have reviewed & discussed (sic) these devices, at length.

I do agree with his order for those devices that I have owned and used.

Bob hasn't tried the Eitr, although he has stated that he thinks they are using older generation devices. Personally my view is that implementation is at least as important ....but I am very happy with the F1.

I am continually amazed at how sensitive these devices are to power variations, wiring & grounding.

 

Hi IB,

Have a gander at Hans Beekhuysen's site or channel on YouTube. He has reviewed many of the devices discussed here, amongst others.

For me, I have just bought the ultraRendu as Sonore seems to me to give good support AND long term customer service, such as the microRendu upgrade path. I also have found that the mR reacts very well to all the upgrades in terms of power supplies etc, so comparative reviews become somewhat moot.

WRT the RPi, I found that moving my LMS server off my NAS and onto the RPi, powered by a LPSU, gave a real uplift to performance. The thread link above goes into detail on the StarTech USB extender and hosting files, a path I have also followed. More recently they have been using LT3045 devices to clean DC with very low PSRR, I have found these to be effective as well. The rabbit hole beckons!

Thanks, I am actually testing an RPi + Allo DigiOne (with 5V ifi power supply) as a replacement for my fitPC3 + TP PSU and  M2Tech HiFace Evo + TP PSU. One small  box instead of 4 mid-sized ones! I am wandering how the new Shiit Eitr compares to the Allo DigiOne, The Eitr seems to be out of stock in Europe at the moment. Best, nbpf

Hi Joe,

Like to praise the customer support of both Sonore & Vortexbox UK. Had an issue which they very efficiently solved. Great service from good HiFi companies is a part of why I choose to buy products, including Naim & EAR-Yoshino.

I have been working quiet hard for the past two months and so decided to treat myself with the uR rather than the mR board upgrade. I had toyed with the SMS variants, but I have been impressed with the way Sonore have included an upgrade path for historic customers.

I am only a couple of days in with the uR. The first thing I noticed was the bass, not just slightly more evident but also the texture. Over the time it has been settling in I have noticed that vocals are a bit clearer, the soundstage is wider and deeper. Positioning within the soundstage is more precise.

Before I post a more considered review I want to spend some time ringing the changes with PSUs etc, currently I am using the SBooster while I have my LPS-1 on my Raspberry Pi 3, serving LMS.

 

NBPF,

I see my link got edited out. Here is an older listing of his order:

Ultra USB chain (details to long to list) 370
BURL B2B DAC with DANTE Brooklyn II/ modded w/LPS power 285
REDNET 3/Cerious Graphene/Mutec 3+ USB (SPDIF)/Antelope OCX (RN wClock) 270
REDNET 3/Cerious/Mutec 3+ USB/Audience au24 se digital cable 250
REDNET 3/Cerious/Mutec 3+ USB (SPDIF reclocker)/AS Sliver Statement dig cable 240

PUC2 Lite TeraDak DC30W/Cerious/Regen 135
Singxer F-1 DC30W/Cerious 135
DXIO Silver/TeraDak DC-30W/Cerious 130
Singxer X-1 DC30W/Cerious/Recovery/DCiPur/iPur2 125
PUC2 Lite - USB power 110
Singxer F-1 Stock feed 110
Breeze/Cerious Graph/WBT RCA Nexgen 109
Breeze DU-U8 with Cerious Graphene 108
Breeze DU-U8 (Talema version) 100
Breeze DU-U8 (BingZi version) 95
Hydra Z with LPS 92
Melodious MX-U8 (upgraded caps) 85
Melodious MX-U8 (stock) 81
Gustard U12 (upgraded caps) 76
Gustard U12 stock 72
iDAC DAC2 (used as a DDC) 65
Musiland USB3.0 US Dragon 65
M2Tech EVO with LPS 60
Audiophileo 2 USB Power 50
M2Tech Hiface 40

The numbers have no absolute reference.

The Rednet boxes use AOIP, for which he was very enthusiastic, ultimately he felt that AOIP delivered huge detail but that somehow the music wasn't as engaging; a bit like how I felt about the Schitt Yggdrasil. He then used a specific StarTech in a particular way & this formed the basis of the Ultra USB chain.

In my case I have owned and used:

M2Tech Hiface; Gustard U12; Breeze DU-U8 (Talema version); Singxer F-1 Stock > Singxer F-1 DC30W/ iPur2/Startech GB LAN Iso USB & the Mutec 3+ Smart Clock USB.

I agree with his ordering. ALTHOUGH, a big issue for me in my system was GROUNDING. Sorting this, with two bits of wire, gave a huge leap in performance.

 

WRT the Eitre: Bob has decried the technology, but Schitt make some excellent kit and so I would not reject it out of hand. You MAY be able to get hold of the Eitre on a trial basis, certainly don't think that will be the case with the F1. If you come over to London you are welcome to come and have a listen!

Very much in line with my observations on the mR 1.4 board upgrade - so good to know I am not hearing things. 

Not surprisingly, the uR and 1.4 mR are cut from the same cloth.

Thanks for the listing and for your own assessment Mr Underhill! I came across that Head-Fi thread and some of its predecessors ... very impressive work. I am still trying to figure out whether the RPi + Allo DigiOne combination is better than my current setup. I guess my hearing is too bad. But I would be interested in trying out the Schiit Eitr should it become available again. It should easily better my current setup. I should probably also try out the Mutec 3+ Smart Clock USB given that I am located in Berlin. Apropos Berlin: if you happen to come over and would like to listen to my system, just get in touch. Best, nbpf.

Hi

I've been using an UltraRendu for about a month. It slotted in to my existing set-up consisting of a MUTEC 3+USB, NDAC with XPS and on in to 52/300DR and QUAD 2805's. It replaced a homemade solution using an ASUS Tinkerboard and Squeezelite. It's powered by and IFI IPower and IFI IConditioner - it is only very slightly warm to touch.

My first thought was, "OK. It's better than the Tinkerboard but not by much". It took me a few days to really appreciate what it was actually doing. It demonstrates great overall competence and it's difficult to single out individual aspects of its performance as being particularly good or outstanding - it simply does everything very well indeed. I'm certainly experiencing the best digital sound that I've ever had at home.

Possibly, the re-clocking in the MUTEC isn't really necessary but in my set-up I need a USB to SPDIF converter and it's the only one I have.

Thanks for reporting, this is very interesting, at least two ways:

First, your observations suggest that the output of the MUTEC is, up to a certain extent, sensitive to the quality of its input: you have replaced the Tinkerboard with the UltraRendu and noticed an improvement in sound quality.

Second, in your system, the pair UltraRendu + MUTEC 3+USB could functionally be replaced by a Raspberry Pi with an Allo DigiOne hat. It would be interesting to know whether this leads to significant losses in sound quality. The RPi + DigiOne combo is much smaller (and significantly cheaper) than the UltraRendu + MUTEC combination!

Hi NBPF

A visit to the CR is long overdue for you then! It would also be interesting to compare the DigiOne with the HiFiBerry Digi+ that I also have.

Actually, we don't live in Prague but in a small village close to the German border - the journey from Berlin is about an hour less than to Prague. The Berlin-Prague express train stops at Usti nad Labem (the last time I used it, it was called the "Karl Maria von Weber Express", after the composer who is buried in Dresden). The D8 autobahn passes close by as well.

If you'd like to organise a trip, I'm on PFM with the same username and you can PM me there.

I have the hiface evo 2 and have found it fantastically unreliable at doing a conversion from USB to spdif (either wired or optical)

Most of the time it simply wont connect. So its gathering dust on the shelf

Possibly, the re-clocking in the MUTEC isn't really necessary but in my set-up I need a USB to SPDIF converter and it's the only one I have.

Hi Chris,

I think the Mutec is a well made device. I just felt that the F1 gave me the same results for a much cheaper price and so I sold it on and used the money to buy a StarTech, to test out another person's recommendation. Now that I have identified and sorted the issue I was having with grounding I wish I could re-try it, but it isn't causing me restless nights.
