Accustic Arts Tube Dac II or Berkley Alpha DAC


Two different approaches. Would be interested in opinions. I currently have a Tube DAC II but it doesn't support hi rez like the Alpha Dac. Considering a change.

You need a preamp. I have a Chord CPA 5000. Thanks Teejay. I purchased the AA Tube DAC II based in part on your excellent review.
When comparing the AA and Berkeley, were they both run through a preamp or was the Berkeley run direct to amp?
In my system Berkeley sound far far better than AA.
Like night and day!
May be tubes was not good in AA.
But it is a fact!
My friend, who bring AA said that it is best DAC he ever heard. But after comparision he bought Berkely!
Murataltuev,
Again, so many questions. Were you running redbook or hi-res into the Berkeley? What transport? What connection? What wire?
Pre-amp or direct? etc. etc.
I know the Berkeley is a fine unit but there are many variables that should be disclosed for some meaningful comparison.
Additionally, what were the variables with the AA when comparing? Obviously a pre-amp had to be used but how about everything else?
