I have the AA Tube DAC with Long plate Buggle Boy Nos. My speakers are Wp7's which can be on the bright side if not used with proper electronics. While I have not heard the Berkley, the warmth and clarity that I hear from my DAC has not left me wanting. I once tried a very well respected digital cable that was recommended by Teajay. In my system it was too bright. It totally changed the character of the DAC. The point is that AA tube DAC is not at all bright or grainy. It has the advantage of being able to tune it to your system by rolling the tubes.
I am sure they are all good Dacs. The only weakness that I see in the AA is that it will not read files higher than 48. High resolution files cannot be used.
