Weaknesses of the Adcom GFA-5802 ?


OK, I mean this is a Pass designed amp right ? I'd like to know how people with experience with it would characterize it's sound. More importantly, what are it's shortcomings or weaknesses ?
Thanks

I've owned many amps and the Adcom GFA 5802 has never been grainy. They do run hot to the touch and many people had the bias dialed back to lower the temperature. The amp throws a deep soundstage with lots of room ambience, lots of low level details, absolutely no harshness and effortless dynamic presentation. 

I see no negatives other than heat.
Unfortunately based on all the variants involved, cables,cd and preamp there is no way the amp will sound the same in your system!  In the past I have had a Rowland, Levinson, Krell, Bryston, Acurus, PSAudio, McCormack and a ton of other amps. I came across an Adcom 555II and the difference between all the other amps, with the exception of the Levinson, were very close.  I had a difficult time accepting that an amp I had bought for $400 could produce a similar sound!  If you were to do the blindfold test it would be difficult to justify the the thousands of dollars that are spent when there is just a subtle difference.  So without hearing the 5802 and knowing that it has the Adcom signature, with balanced as a bonus, I know that it has to be a worthy contender.
Are the new Adcom amps an improvement? their specs look very similar to Parasound amps.   I've not seen much press about the the newer units.
