Al,
again; sorry for the delay in my response. busy, busy.
I can't say about the Berkeley, but I am now a big time believer in 44.1/16-Redbook as a completely worthy format in every way. but I would add that it takes some great engineering and likely high $$$'s to be able to enjoy that.
if you read this description about how the Trinity adds analog points to the upsampling and the value of it's very expensive clocks....

and this post about how the Trinity differs from conventional dacs....

I think that you begin to appreciate what it takes to take PCM beyond it's weak aspects. it can be done but the efforts are considerable.
i'm going to guess that the Berkeley has it's own tricks to overcome these same challenges.
enjoy!
Mike,
thanks for the reply. Yes, the Berkeley Alpha DAC has its own tricks, but there is no doubt that the Trinity DAC is the superior design. The Berkeley Reference DAC is another beast than my regular Alpha DAC altogether, since it uses highly advanced clocking like the Trinity does, but I do not know how it would compare in sound quality (it might very well be that the Trinity is superior still). In any case, the resolution of the Berkeley Alpha DAC is good enough to convince me of the worth of the CD format, in the sense that it has much more resolution than I had given the format credit for -- and it should have more potential still than the Berkeley Alpha DAC allows you to hear, a potential that probably the Trinity DAC unlocks to a greater extent.
Regardless, I enjoy my CDs very much. The vividness of presentation is excellent through my DAC, as is the lack of fatigue and digital harshness, and like you I have spent considerable effort on getting room acoustics right. The latest acoustic upgrades (ASC window plugs; i have lots of windows) allow me to hear much more timbral resolution from the Berkeley DAC, and the CD format in general, than it had been the case before; a particularly good example for progress in resolution is solo violin. Also, some hardness on solo strings playing at high volume that I previously had attributed to digital was simply the result of unresolved problems with room acoustics which have now been addressed.
I am now a big time believer in 44.1/16-Redbook as a completely worthy format in every way.
That is great to hear. You also say that higher-rez PCM is better still -- how much better in your opinion?
