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.

Hi Brilliant,

I find my Chinese Zero Zone R-Core 6A 8v LPSU > LT3045 better than the LPS-1, and has the BODY. I believe the LPS-1.2 now incorporates LT3045s.

I lied above, I used the chain for a day then tried slotting the IFI iPurifier 2 back in. It acts like a concentrator, focuses what is fed into it to great effect.

One thing I have noticed is that making more current available to a widget adds body/dynamics .....but, is this necessarily a good thing? So I am currently (sic) running my ultraRendu with just one 1A 7V2 LT3045, rather than 2. I'll report back in due course.

Hi M

yes the LPS - 1.2 output has the 2xLT-3045 in //. Works great with the uR. Great resolution.

Brilliant,

If you can borrow them with a return policy I would have a go with the IFI Mercury USB 3.0 followed by the IFI iPurifier 2.0 between the uR and the DAC-v1.

Yes, the LT3045s are a good move, drop the noise floor waaaaaaaay down.

<tangent warning>
Those Celestions are classic speakers, if I remember were reviewed as painting an excellent sound field, but rather inefficient - and can lack dynamics ......and, needs GOOD amplification. Are you using these or your own jobbies?
</tangent warning>

M,

Theh setup is using my own jobbies in the main system - much more revealing for this sort of thing. The lovely Celestions are in the den.  I'll wander over to the Audio Show going on here at the moment and see if they have the iFIs - thanks for the tip.

Well since this thread has been resurrected I might as well make my first post!

I have followed this thread since inception and would like to know people's opinions of the MicroRendu vs. UltraRendu.  I have spent the past year playing with a stand alone headphone system - completely separate from my Naim 500 kit.  I have purchased a few TOTL headphones and currently run them from a new Sony Signature Series stand alone DAC/Headphone amp (completely separate from my 2 channel system) and also from a Moon headphone amp plugged into my Naim preamp and using my Linn Klimax DS as a source.

I am familiar with the Sonore products as I own their "intro" model SonicOrbiter SE which was discovered via the Linn forum last year as a way to bring ROON integration to our DS's.  I am currently using it with the Sony DAC/Amp for headphone use as my files are stored on an external hard drive connected to an iMac in the kitchen.  The SonicOrbiter SE acts as a ROON endpoint and brings the files to the DAC/Amp.

A few PM's with the Sonore boys have indicated that my SonicOrbiter is a "toy" made for a specific purpose and that the MicroRendu is leagues better.  This weekend (Easter) they are running a flash sale on the MicroRendu at $499 (vs. $640) and at that price it is tempting to upgrade.  I just want to make sure I am not making a mistake by not simply going with the UltraRendu ($900).  How much of a difference is there between the two?  Reading online, and even in some PM conversations with Sonore, it seems that the UltraRendu provides that famous last 10% of usual audio goodness - not always the best money for value quotient that we all are familiar with.  It is also strictly to use with the headphone system as the serious listening is done with the Naim/KDS system.

One additional thing they were rather adamant about - using a dedicated LPS power supply regardless of which model Rendu I go with.  They seem to be fond of the Channel Islands version (I am in the States).

So - holiday promo deal on the MicroRendu or UltraRendu?

PS the upgrade program for the MicroRendu is now over as there are no more boards left.  For a new purchase it never made sense anyways as one should go instead direct to the UltraRendu

Posted on: 31 March 2018 by charlesphoto

Having ju1st done one of the last of the 1.4 board upgrades on my  microRendu, I would say go for the Ultra if you can stretch it if you are after ultimate sound quality. The original rendu will get you 60% there, 1.4 board 90%. I guess it depends on your other gear as well, and how revealing your dac is, and what you plan on doing for a power supply, and of course your budget. $499 is a good price for the rendu, if that’s your ultimate budget, and will be much better than the SE by all accounts. I lived happily with mine from almost the day they came out, but so glad I sneaked in the 1.4 upgrade. Lots of used Uptone LPS-1’s on the market now since they announced the 1.2 version, and that is considered one of the best ps for the rendu.

Posted on: 31 March 2018 by Brilliant

Putting myself in your position and imagining a 500 level system in the house, even in another room  I would start with the ultraRendu. If you like it (which I am betting you will) then upgrade the ps with a LPS later on. Sonore gives you a trial period I believe. If you decide to return it,  the ComputerAudiophile Marketplace usually shows mRs or SOTM sms units for sale in the $300 range.

Posted on: 31 March 2018 by charlesphoto

Keep in mind there are used 1.4 microrendu’s out there too. Quick search using hifi shark and there is one listed on Audio Circle for $675. They come up pretty regularly as people upgrade to the Ultra or other streaming options. I would’ve gone for an Ultra if I wouldn’t have lost so much in reselling the micro, so the board upgrade made sense while it was still (just) available. 

Posted on: 31 March 2018 by glevethan

Thank you for the replies.  Yes I am on the fence and I guess I have today and tomorrow to think as the Sonore promotion ends tomorrow night.  I even inquired if the promo price  applied to the UltraRendu however it did not - the flash sale was only put on due to MR inventory levels.  That leads me to believe they have too many MicroRendu's and are looking to clear them out - perhaps most people are now going for the Ultra? 

I have a sneaking suspicion that in the end I will end up with the Ultra.  Since my iMac/external HD w/ Flac files resides downstairs in the kitchen the only way to get music to my dedicated listening room is via ethernet.  That is how I feed the Klimax DS.  So ultimately where ever my DAC journeys take me for the headphone system a device such as the UltraRendu is mandatory and will grow with me as it is the only way to get the music files into the listening room.

Power supply recommendations are strange - I have read quite a lot about the new version of the Uptone - Sonore even claims the external case of the UltraRendu was designed to match the Uptone supply - yet in private correspondence with me they tout the Channel Islands brand power supply.  I am curious to know why - do they think it is better - or perhaps some political squabbling with the Uptone folks?

I also have read that with the UltraRendu people no longer need to bother with USB regeneration boxes (such as what Uptone sells) as the UltraRendu internally takes care of this problem.  Possibly another reason to go in the direction of the Ultra as I do not want to get bogged down again with a multitude of external boxes.  I am into simplicity as I get older - part of the reason why I culled my black boxes and went for a simple internal Urika in my LP12 - losing a SuperLine and SuperCap in the process.

USB cables - what are people using?  I again do not want to go down the same rabbit hole I did with my Naim system (Chord Music throughout).  I have seen some reasonably priced recommendations made for Oyaide Neo d+ Series Class S USB Cable, Supra USB cables, Vertere Pulse (although not easily available in the States) - all priced around $100.  Are these some of the popular reasonably priced ones?

You do know you can feed Roon to anything using the Bridge app in the microRendu (I suspect you are already doing this with the SE). 

If you can fit it, the Uptone USPCB is a great option, and what I use with my V1. It can be purchased straight or twisted 90 degrees. You will need to rig up some sort of support (I used legos from my son’s bin). It runs about $35 I think. You may also want to consider the Ghent Audio JSSG USB cable, if you need an actual cable.

Not heard of Channel Island. I always thought of Sonore and Uptone having a symbiotic relationship, but perhaps not. 

Posted on: 31 March 2018 by glevethan

Yes - I am currently using the new Sony Signature Series Headphone DAC/Amp and am in fact using the SonicOrbiterSE as a ROON endpoint.  I was pleasantly surprised with the sound I am getting and can only imagine what a MR or UR would bring to the equation.  My intent is to use the Sonore product in this fashion as I want to have ROON for my headphone system.

Something like the Uptone USPCB is interesting as this was one of the benefits the Sonore boys were touting in using a MR instead of the UR - the need to not spend further money on a USB cable and instead use the included hard USB adapter.  The only thing they said is that it would be more difficult with the UR due to the much larger case size.  Some improvisation would definitely be needed.

Hi Glevethan,

Welcome to the thread!

I would agree with the above. Only you will know how much digital listening you will do and whether the extra the ultra offers will tempt you if you don't opt for it, personally it is the one I have and I would recommend.

PSU: I would recommend getting a 6A/8V R-Core Zero Zone LPSU from eBay and then follow this with two 1A 7.2V LT3045s; this is better than an LPS-1 and for less than half the price. The LTs will require a couple of project boxes, DC connectors and a tiny bit of soldering but is WELL worth the effort.

The cable I would recommend is the IFI Mercury 3.0, the PCUSB is excellent VFM and has been 2nd best in my system.

The best chain I have found, and I have done a LOT of testing is:

ultraRendu > PCUSB > Uptone Iso Regen (powered by a 0.5A/5v LT3045 - hence the 6A/8V LPSU) > IFI iDefender 3.0 > IFI Mercury 3 > IFI iPower 2.0

In my case this feeds a Matrix SPDIF2 & then a Border Patrol SE DAC.

Look forward to reading your decision and then thoughts.

Mr Underhill

Thanks for this.  I think I will need to spend some time on Google to figure some of this out!

While the power supply recommendations I am sure are valid they are a bit DIY.  Something like the NEW Uptone LPS-1.2 may be easier and was designed (case wise) to match up with the UltraRendu.  Some of the house issues with the first generation were apparently fixed.

The Iso Regenerator - what about what I have read which says that this is no longer necessary when moving up from the MR to UR - that the UR has this capability already built in?

Re Ifi - off to the website to decipher what these boxes do.

Comments not directed towards your setup but rather to the numerous setups I see on the CA forum where people have 10 different boxes etc. all to achieve the best in digital sound - it makes me appreciate Linn even more that they are able to take care of everything in one single box.  One has to admire how smart they were way back when ten years ago when all of this was in its infancy.  The lengths that people go to fix the inherent problems with USB ie Regenerators, cables, isolators etc. and Linn discovered in its infancy that bringing in the files via Ethernet was the way to go.  Smart chaps those boys up in Scitland!

I’ve had a microRendu in my system for the last week and can vouch for the fact the engineers at Sonore have created a little network audio gem. I have it connected to the USB input of my DAC-V1 using the Uptone USPCB A to B USB Adapter. Why would I want to potentially undo all the good work of the engineers at Sonore, and at Naim, by introducing components, into the data chain, which can potentially do more harm than good. I was always brought up to believe the weakest link are the connectors. Keep the signal path as short as possible is my motto.

If you wish to upgrade there's the UltraRendu or, for those with very deep pockets, Sonore Signature Rendu SE. Not forgetting the recommended PSU options of course.

Right but to keep the signal path as short as possible we need servers and network players with high quality outputs that match the inputs of our DACs. We need modular designs and the option of ordering the devices with the outputs that we need. Finally, we need flexible and usable devices: it does not make very much sense to invest time and money in software solutions that are obsolete or that only work for pop music. Some folks at CA have successfully replaced long replay chains with simple solutions based on Innuos servers. The new Antipodes also look quite promising. And, in terms of flexibility, straightforwardness and price a DigiOne directly connected to a S/PDIF DAC is likely unbeatable. It also sounds quite good to my ears ...

Hi Glevethan,

Shame you are on the other side of the pond, makes doing a demo a tad more awkward.

I think you will be able to find a supplier who will sell you the ingredients on sale or return. You'll get most the effect with the iDefender, Mercury 3.0 and iPurifier 2.0, without the Iso Regen.

If you can manage the LT3045s they are well worth the effect, and will allow the R-Core to be better than, and half the price of, the Uptone. But, I understand the DIY hesitation.

I completely agree these chains of gadgets appear to be ridiculous. They are additive. The Mercury is the ONE cable I have found that revealed detail that the PCUSB didn't, and the iPurifier acts like a concentrator. The mR or uR plus the PCUSB will give a very nice result, the rest is icing, but isn't icing enticing!

Hi M,

Thank you for the suggestion. I did briefly check out the iFi Mercury3 (USB 2, 1m -with only a few hours on it) & iPurifier2 (USB B, a shop floor unitl) in my main system.

First of all- I  use the 90 deg A>B USPCB in the  uRendu>DAC-V1 setup. The V1 will not accommodate the uRendu width with the straight USPCB! This means that the uRendu orientation is vertical rather than horizontal.  To hook it up horizontally, I can use  two USPCBs with a B>A adapter between them but  I find that this degrades the performance slightly. Why do I mention this - I believe the 90 deg USPCB performs better than my straight ones when used with ISO-Regen. I do not know if this is due to normal variability or physical orientation. Does this apply to the uR setup as well? I do not know, but I like what I hear.

I listened to some familiar tracks as follows;

1. start with: LPS-1.2->(uR->USPCB, 90deg)->DAC-V1.

Listen for a while, to get a mental baseline.

2.  add the iPurifier2 to the setup: LPS-1.2->(uR>USPCB, 90deg)->iPuriifer2->DAC-V1

I felt that there was a slight  'softness' added to the sound. This could help in an 'edgy' setup.

3. use just the Mercury3 cable. LPS-1.2->(uR->Mercury3->DAC-V1

I found it to be very good, with a slightly 'rounded' sound when compared to 1. Again this might help in some setups. As mentioned earlier it only had a few hours on it so I do not know whether it had reached 'break in' status! I did not play with the ferrites location much, so cannot comment on the ability to 'tune' this rather unique and fine sounding USB cable.

4.  add the iPurifier2 to the Mercry3. LPS-1.2->(uR->Mercury3->iPurifier2->DAC-V1

I found it to be as good or slightly better than 3. (not sure)! I would need to listen some more.

5. Return to 1.

I can only describe 1. as the  'purest' sound and ultimately the most musically communicative to me. It suits me the best in my setup.

Having said that I can see (hear?)  how these iFi components can benefit an  'edgy/hard' sounding setup.

ATB.

I'm using the microRendu as in Brilliant's set-up 1 above, i.e. microRendu -> USPCB, 90deg -> DAC-V1.

Currently I'm powering the microRendu using the stock Meanwell 7.5v SMPS but looking at upgrade options. I know the LPS-1, now I believe superceeded by the LPS-1.2, is highly regarded.

Any thoughts and/or recommenations would be welcome.

Dave

Posted on: 13 April 2018 by Brilliant

@Dave,

In a week or two,  I can listen to and post my impressions of the DAC-V1 with the  mR/LPS 1/Iso-Regen, vs LPS1.2 etc if you like

 My feeling is that the DAC-V1 still has great potential on the USB interface (as evidenced when fed a clean signal) and I would not be surprised if  NAIM works this toward a V2. Imagine if they added an A/D convertor and a digital out option for the archiving of LPs or general digital recording!

Posted on: 13 April 2018 by charlesphoto

Dave, using a 1.4 microRendu with 90 degree uspcb into V1 myself with LPS-1. 

Definitely lowers the noise floor considerably, even from an iFi and HDPLEX lps that I cycled through first. Pretty sure the lps-1.2 brings even more to the game. 

Would love to see a V2 with analog in too.

[@mention:1566878603960960] @Charlesphoto

Thanks for the feedback.

I would certainly be interesting to hear comments comparing LPS-1 and LPS-1.2. I believe the LPS-1.2 is now supplied with a customised 7.5v energiser and not the Meanwell.

I'm not sure the LPS-1.2 is available on this side of the pond yet but there are a couple of LPS-1's for sale, on that well known auction site, so I'm not sure wether I should jump or wait.

Regarding the DAC-V1 I would definitely agree with your comments. Installing the uR has really made me appreciate it's capabilities as an USB source. I'm sure I can squeeze a bit more out of it yet.

Dave

Posted on: 13 April 2018 by Brilliant

The LPS 1.2 consumes more power when charging (36 W). I am guessing your uR above refers to your microRendu rather than the ultraRendu. I have not tried the LPS 1.2 with the microRendu yet. The LPS-1.2 has  a noticeable performance advantage over the LPS-1 when used with the ultraRendu, most noted in the resolution of the lower frequencies!

I imagine there will be a few LPS-1s on sale for a while due to the1.2 intro.

Posted on: 13 April 2018 by charlesphoto

I also have the Ghent Audio DC cable with Oyaide 45 on both ends, as well as their JSSG ethernet cable with Metz connectors one at 45. The 45's help as the microRendu is close to the wall. Affordable, well built, and neutral. Built a little holder out of spare legos (kids are good for something). Some grungebusters under the feet of the LPS-1 and a cheap heatsink and weight on top. LPS-1 is charged by an HDPLEX. I guess the new charger that comes with LPS-1.2 is all that you need to break leakage.

Semi-non sequitur if you’ll forgive me - my question doesn’t really merit its own thread. Earlier in this thread, there is  discussion of a power source for the rendu. Seems unlikely, but is there any merit (or madness) in connecting it to a powered aux input on a nac? 

Posted on: 14 April 2018 by charlesphoto

Egads man! Only merit would be if you want to fry your rendu. Rendu is 7v best, 9v max. I believe output on NAP is 24 (or is it 13?). Anyway, maybe with some sort of drop down, but there’s a reason to bite the bullet and go with a purpose built power supply for these low voltage dc devices. If money was no object, I would go for the Uptone JS-2 at $995, or their LPS-1.2 at less than half that. The new HDPLEX 200 watt coming out in May looks like a contender as well at $485. Multi rail ones are nice for their flexibility in powering different devices. Lots out there and many of the cheap Chinese ones work as well, esp for aux devices. Just choose high, and wisely. 

Best,
