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!
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
with iFi power supply $690.00 (Sonore)
or add Sonore Signature Power Supply $1,399.00; $1,589.00 with Synergistic Research black fuses
or add HDPlex power supplu using 7.5 vdc output $395.00
Sonic Transporter AP 8TM (Roon Server) $1,575.00
(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!
