In Reply to: UPDATE Comparison: OPA627's vs AD8620's in Audio Alchemy DDE1.2 DAC's Analog Output posted by dtm1962 on April 22, 2003 at 20:26:54:
I've been listening to the OPA637 BPs in a different application and think they sound very nice. They are said to be similar to the opa627s, but have slightly better specs and are only stable for gains of 5 or more.I've gone to positive biasing on my AD825s -- about 1.5mA in my DAC. They seem a bit better this way -- a bit more lifelike, verses the negative bias. I don't have a firm grasp on the changes yet, because I've been borrowing a friend's amp and am less sensitive to listening differences.
For myself it's impossible to say how the opa637s compare to the AD825s because they are in different applications. I do like both though.
