I bought a Berkley to hear for myself in my own set-up, I only play redbook and don't care about HiRez;
Set-up;
MBL 101E speakers
Bryston 28 Squared mono blocks
Audio Research Ref3
MBL Ref 1621a transport
Acustic Arts Tube Dac (not stock tubes or fuses or power cable)
Stealth Audio Sextet digital AES cable
Steath cables through out
I don't know what you guys are hearing but in my set-up I most definitely prefer the AA pce. and so did eight others, as Teajay said "much more musical/natural sounding to my ear's", I have to agree with Teajay so it's obvious that we prefer a different sound.
