Review of SW1X Universal Music Server UMS1 Signature and Universal Power Supply
Over the last 50 years I have owned some pretty exotic and expensive audio gear spanning £7000 amplifiers and 6ft tall horn speakers. After each upgrade it was easy to persuade myself that things were better, but in hindsight things were just different.
Some ten years ago I moved across to computer based music, dispensing with my Linn Sondek, Ittok etc and Counterpoint CD12 player once I had a computer based system that competed sonically. My computer software, from a limited choice back then was XXHighend by Phasure. Over the years that followed, the software showed glimpses of excellence but was upgraded with corresponding bugs and glitches probably 10 times every year. I felt like a (poor) computer programmer and lost my appetite for Hi Fi.
Enter SW1X and Slawa.
I visited with scepticism after others had looked at pictures of his gear and branded it as Chinese import – a slur that really upset Slawa. How wrong we all were. From that moment my Hi Fi life was rejuvenated. Even his starter system had all the attributes I had been seeking, sounding analogue like and in particular giving the resolution and transparency to hear a change of mains cable or a single capacitor in a DAC. In the past I had nodded along to salesmen that substituted interconnects, hearing just minute differences and believing this was all you got for your money at such a high level.
Cutting a long story short. I treated myself to much of Slawa's level 1 Signature stuff and moved over to vintage open baffle speakers. At the same time I had to resolve the computing side of it and bought a Raspberry Pi with Moode software and a pair of 45 Valve monoblocks to feed a lovely 2 watts to the new speakers. Having made so many changes I had no real reference sound to judge against but was well pleased that I now had a system encouraging me to listen late into the night, though I still felt Slawa's system had the edge.
It was becoming obvious that the Moode software people were making no significant strides to improve audio quality with their updates, preferring to concentrate on the user interface and multiple streaming applications which was not where I wanted to go. Sound quality was paramount. Also I had my reservations about the switching power supply on the RPI, which was soon replaced by a Longdog Audio linear power supply. For a relatively modest outlay it brought the improvements promised.
Here I stayed happily for many months visiting the Windsor Hi Fi show in the meantime to hear the 'competition' that in the majority were still battling to push nasty digital sounding systems. Slawa announced he was about to build a Universal Music Server and separate Power Supply Unit and I offered to bring over my PRI with power supply to benchmark how good his was. Well it was like a non league football team challenging Chelsea to a duel.
So I bought the UMS1 fitted with 1Tb of SSHD and UPS1 signature models.
If you want the technical stuff its here on Slawa's Web Site.

Its almost impossible to convey the sound of a component, but lets just say it ticks all the boxes with superlatives.
Enhanced bass
Full midrange
Sweet top end
Excellent imaging
Everything sounds so lifelike
Not a hint of digital nastiness
Good as it was, this combination leaves the PRI dead in the water
Wonderful boogey factor reminding me somewhat of early Naim gear in that area.
Timbre is spot on.
Its perfectly quiet - no fan noises and no spinning hard drives.
Some would argue that at the price it should leave the RPI for dead, but this lays waste to those that claim computers all sound the similar.
Now my system sounds just like Slawa's and for that I can pay no higher compliment.
Not all power supplies are created equally
Not all power supplies are created equally- if one decided to upgrade a power supply of a computer with a third party power supply one most likely will hear some sort of difference but may also experience a disappointment. That is not going to be very surprising as we have not seen many manufacturers out there to take the aspects of sound quality that we promote seriously. Most of the after market power supplies I have seen on Ebay for example have one flaw or another in their design or implementation. Many people will be surprised to hear this but every part in all those power supplies contributes to the sound. If something was left to chance in those power supplies, the sound will manifest itself accordingly as a result.

The sound quality is the most important objective- everything else is secondary
Dear Bruce,
SW1X UMS I is an universal music server - i.e. one could run any OS (Linux, OSX, Win, Android etc.) on it including Roon with any integration one desires. However, there are some reasons as why we opted out for Daphile:
1. Sound - it has a sound signature that reminds me of Black Gate capacitors. It has a pitch dark background and a thick body in the mid bass area relative to Windows and OSX, which all sound thin and noisy in direct comparison.
2. Straight forward, elegant minimalism of its OS architecture (a la Linux), similar to Rune
3. Compatibility to Squeezelite clients
4. Relatively intuitive and user friendly without unnecessary rubbish like equilizers, upsampling etc.
As regarding external remote steaming services functionalities- I could care less about them (even local ones, which are possible) because 1. all of my music is stored locally and 2. more importantly the sound quality of local playback is indefinitely much better (musical) sounding that of remotely streamed content.
The sound quality (musicality) is the most important objective- everything else is secondary.
