Just to show how weird this pursuit of “ultimate sound” is… Its hopefully point for discussion of how subjective perception of best SQ is.
I have MK1 for about 2 years. I had transformers upgrade and some major internal upgrades in UK ( not affiliated):
KEF reference 207
KEF PSW4000 subs (4) - very large living room.
I really appreciated all that PS audio does ( hence components). I have tried everything to get that “analogue sound”, inc tube rolling etc.
I used I2S and matrix/other DDC’s , stupidly expensive cables.
Yes, I could achieve everything resolution wise, jaw dropping detail, dynamics etc.
I avoided using USB as everyone advised against it in favour of I2S.
Anyhow with time I acquired Sonore Signature Rendu SE after I found Airlens to be thin sounding no better than PC asio.
After using Sonore with DDC, I was still not there, sound was better but…
Anyhow after discussing with Sonore they advised to use DAC USB input, BUT with Fiber interface ( Zero Noise). No need/use for galvanic insulation.
And it was great improvement, everything started coming together.
Finally I started “rolling back” dac firmware. Windom sounded better to me than Sunlight, Snowmass was again little bit better. Then I installed Redcloud and I could not believe, everything just came together.
Instead of chasing detail I finally got “my” analogue sound. Rich, mature and just right. No more chasing this and that , it was just music pouring out & nothing more or less.
So now I finally enjoy my setup. This hi-fi game is not easy.
I just wanted to share my experience and of course yours will be different. Thank you for reading.
None of this would be possible without Ted/Paul, which made DAC that can change system character in under 5 min. Congrats PS Audio!
