My Sonore Microrendu came in today! Installed mid-afternoon today. Have used XLO Reference Recordings burn-in disc. Checked sonics at about 3, 6 and 10 hours of playing/burn-in.

At the 3 hour mark, if that was the best, then I would charitably say great product for the money but not for me, vocals were somewhat flat, same for bass and high end, lack of midrange. Patience.

At the 6 hour mark, soundin’ better, but would not replace or equal my CAPSv4 sonically.

At the 10 hour mark, soundin’ marvelous, as good as my CAPSv4 in every respect, and I think
perhaps a bit more 3d in placement of voices and instruments on some stuff.

Count this as a 3 round win for the microrendu!!! Its everything that Andrew Gillis, Small Green Computer, told me it was sonically, in my system when used as the Roon Bridge!!! For only $640! It’s a steal!

You mean you don't remember me? Back 1999 - 2003, I started and moderated the AVS Tweaks forum and also the AVS Special Guests forum.

I’ve been using the HDPlex linear power supply (that I bought with my CAPSv4 Pipeline,from Small Green Computer), using the 9VDC connection, for the Microrendu, which works fine but does run towards the hot side (the Microrendu accepts from 6 – 9VDC). As I purchased this power supply with my CAPSv4, the 9VDC output is not adjustable down to 7.5VDC, as is one available direct from HDPlex. (Small Green Computer had the option of purchasing the more traditional and relatively inexpensive (about $60) iFi Power Supply, which I understand runs at either 7 or 7.5VDC, such that the Microrendu does ot get hot. Also,Sonore also has its top of the line Signature Series Power Supply for the Microrendu to optimize performance – “only $1,399: http://rendu.sonore.us/signature-ser...er-supply.html)

Last night I decided to use the CAPSv4 again to verify how the Microrendu sounds in comparison. I played the 4XDSD “8 Ensembles in 1 Bit” from www.nativedsd.com. This album is great demo material with some outstanding classical and acappela! I previously ascertained that the Microrendu sounded at least as good as the CAPSv4, with the Microrendu perhaps being more 3d on instrument and voice placement, both using the same HDPlex power supply. Frankly, on using the CAPSv4 again, I was somewhat shocked – the Microrendu simply is clearly appreciably more 3D and overall sounds appreciably better, not just somewhat, than the CAPSv4! I heard this on the classical instrumental and the acapella!

So I decided what the hell, its only money, and I just ordered the Signature Series Power Supply for the Microrendu!

Run it as an HQPlayer NAA off Roon, and you may achieve true audio nirvana.

So I decided what the hell, its only money, and I just ordered the Signature Series Power Supply for the Microrendu!

My Microrendu using my previous HDPlex 100 watt power supply, 9vdc output (came with my CAPSv4 Pipeline, you can buy one direct from HDPlex with adjustable down to 7.5vdc output) sounded appreciably better than my CAPSv4! Just put in the Sonore Signature Power Supply yesterday at noon.

The Microrendu is speced for 6 - 9 vdc. The Sonore Signature Power Supply is 7vdc, which Sonore in their testing for their Microrendu found as their sweet spot. With the HDPlex at 9 vdc, Microrendu got quite hot. With Sonore at 7 vdc, its barely warm!

I have used a laptop, Bryston BDP-1 (5), CAPSv3 (4), CAPSv4 (2) , even an Aurender (3), and now Microrendu (1), with each having different sonics. I have rated the sonics over the past several years in my system for stereo, with (1) being the best, (5) being the "worst". The Bryston was digital out, all the rest were USB out using the Berkeley Audio USB to digital converter.

The MicroRendu is the real thing!!@@

Main Roon program runs on my CAPSv3, which I also use for multi-channel over HDMI with JRiver Media Center. MicroRendu is Roon ready and does the sample rate/bit rate conversion and outputs audio via USB - to my Berkeley Audio USB to digital output, which goes to my Theta CBIV SSP out digital to my Theta Digital Generation VIII Series 3 DAC, for stereo!

Microrendu (Roon Ready) $640.00
http://microjukebox.com/products/microrendu
with iFi power supply $690.00 (Sonore)
http://www.microrendu.sonore.us/
or add Sonore Signature Power Supply $1,399.00; $1,589.00 with Synergistic Research black fuses
http://rendu.sonore.us/signature-ser...er-supply.html
or add HDPlex power supplu using 7.5 vdc output $395.00
http://www.hd-plex.com/HDPLEX-Fanles...CE-device.html

Sonic Transporter AP 8TM (Roon Server) $1,575.00
http://microjukebox.com/products/son...tb-roon-server
(music server Steve Williams mentioned, which will run programs like the main Roon)

(If I was doing a completely new two channel music server system, I would consider getting the Sonic Transporter AP 8TM. But I already have a Western Digital WDMyCloudEX4 - 16 TB - using my multi-channel CAPSv3 Zuma to run the main Roon program.)

I will say that I was startled by the sonic improvement from using the HDPlex at 9 vdc and the Sonore Signature at 7 vdc. Using the HDplex with the Microrendu was quite an improvement over my CAPSv4 Pipeline (using a Berkeley Audio USB to digital converter, to Theta Digital Casablanca IV SSP digital out to Generation VIII Series 3 DAC, with Aerial Acoustics 7ts and two JL Audio f212 subwoofers, with Theta CBIV using Dirac Live as well). But changing the power supply to the Sonore was far more breathtaking, on all sorts of music that I played! Voices became ethereal, present in the room totally separate from the instrumentals. I could feel the various jazz players & instruments right in front of me. Now I don't have the time or patience to try out other power supplies - so I can't tell you how they sound. I can't imagine how any other power supply could sound better - that's how good it sounds now, or shall I say midnite last night with only 12 hours break in (using XLO Reference Recordings Test Disc tracks). Note that the HDPlex power supply, from my CAPSv4, output 9 vdc and the Microrendu was on the bottom end of hot, not too hot too hold. With the Sonore power supply, the Microrendu is not even warm. And the Sonore power supply itself is not even warm. And shame on me, I have some extra old tweaks lying around, so I placed the Sonore power supply on a set of Symposium Rollerblocks, on top of a Symposium Svelte Shelf. Oh - I have not in the past used audiophile fuses, but this time, I went ahead and paid extra for the Synergistic Research black fuses (2) which is an option on the Sonore website. Interesting is that after about 3 hours break-in I really liked the Sonics but noted that the system just didn't seem to sound as well or handle the audio as well when I really started to turn up the volume (I have a large theater room, 25' X 18' X 12' high, with Michael Greene Pressure Zone Controllers for acoustics treatments) - but 9 hours later, midnite last nite, the audio/system was purring along and sounded phenomenal regardless of volume level - not unusual, I've experienced the burn-in phenomena many times over the years. Also, when I set up the new power supply yesterday, I took out the .8M Curious Cable, and just got and inserted the short Curious Cable Regen Link - so the cable and power supply are burning in!

Here's some more info from Jesus, of Sonore, regarding the Sonore Signuture Power Supply that I am using and love!

It is quite likely that the JS-2 would work very well with the µRendu, but it would be best if the JS-2 was solely powering the µRendu alone, as a dedicated supply is always going to have a technical advantage to a shared supply (shared transformer in this case). As to why the SPS is so good, that is pretty easy. The SPS is designed specifically to provide an ultra low noise, and ultra low impedance supply for the µRendu. It is designed to be able to provide plenty of peak current, giving it generous headroom. And it is designed to meet the ideal power requirements of the µRendu according to John Swenson: low impedance delivery, the ability to handle all kinds of transients with fast response and settling. In addition, and unlike some of the other supplies mentioned here, the SPS also offers the lowest noise possible from a regulated supply, by using an ideal, custom, discrete regulator. I know John believes that super low noise is not necessarily a requirement for the µRendu power supply, and I understand his point, as he already uses quite low noise local regulators onboard the µRendu. But my experience has always been that even with very low noise local regs, a low noise pre-regulated supply still brings benefits when powering digital circuits. So, with the SPS we have an ultra low impedance (to handle transient loads) and ultra low noise supply, with plenty of current capability. How we do this is just pretty standard stuff, well chosen parts, a damped transformer secondary to keep ringing to a minimum, a bit of filtering on the incoming AC line, large amounts of main supply filter capacitance, and a really, really good discrete regulator. A bit of a note on the price of the SPS: this is high quality audio product, with many parts sourced from the US, including a very nice aluminum chassis, and a custom made DC cable produced for us by Cardas, and it is hand built to order. While we might be able to achieve similar performance with a much cheaper chassis, at a bit lower price point, we made the SPS to be high quality inside and out, and so we put it in beautiful custom chassis of heavy gauge aluminum, rather than some off the shelf box made in China.

There is quite a bit of space in the middle of the chassis so that the transformer and AC input wiring can be spaced away from the output board. Then there is the input IEC with filter capacitor, switch and fuses on the transformer side, and a Neutrik Powercon jack on the power supply board side with the output wiring. I would rather not talk about specific part choices, as these are both proprietary and subject to change, occasionally.
Well I am certainly impressed, objectively and most importantly sonically! The Sonore Signature Power Supply is so well built and easy to look at! More importantly, the sonics using this power supply with the Microrendu are unparalled! I feel like the gal singin' or the band playin' is right in the room with me! Amazing! Congrats on phenomenal products, the Microrendu and the Sonore Signature Power Supply. In my case, I decided to get it with the Synergistic Research black fuses (2) (product just became available a few months ago), for which Sonore is also a dealer.
