@zlone sure
I will start with Bricasti…
The M3 is a fine DAC. Having owned it for quiet some time with different amps, preamps and integrated amps, the sound signature is pretty neutral and accurate. It has good details, is never in your face and keeps the presentation safe enough to not even remotely approach digital hash or harshness. I felt it was specifically designed to be a bit reserved in that regard to create an impression of refined sound but st the expense of musical engagement. It’s a matter of fact, accurate and natural sounding DAC. Soundstage is good, but again the overly cautious approach results in kind of a general view of what’s going on in a recording and it isn’t extremely precise or focused.
That was my impression of M3 in my system.
What you get with Meitner is still a very natural and refined sound but now you have better focus, you hear deeper into the recording with more details and layers in a soundstage, better instrument separation and most importantly a very nice step up in musicality. It is not a warm or dark sounding DAC. Yes system matching is key but it replaced the M3 with all associated equipment intact.
I later replaced Nordost Frey 2 power cord on Meitner with Kimber PK14 Ascent and like it better.
