Adcom a weak link?


Interested in your opinions. My bedroom system in JSE .6 speakers, Atoll Pr5.1 and Adcom 7400. I'm using 2 channels of the Adcom. 

I've read mixed reviews on Adcom. I want to get the most out of my system, of course.

Would you replace the Adcom with a 2 channel amp, preowned under say $700? Or my other interest is a Nuprime IDA8 integrated.

I like the Atoll, that's why I'm considering another amp. My ears are not sophisticated, so if you feel the improvement would be highly subjective, please say so.

Unfortunately, no local dealers near me to demo, etc.

Thanks

For what it's worth, I rotate Silverline Minuets in the system as well. So the best solution will perform well with either speaker.

Why do you want to move away from Adcom?  Is there something that you don't like about it, or are you simply influenced by what others have to say?  I have a very elaborate/expensive system, but sometimes just listening to my Denon receiver can be as rewarding.  Once you get on the "upgrade train", you will wind up with a very thin wallet, and still be unsatisfied.
I have an old Adcom 555. When I restarted my audio purchases, I bought a McCormack DNA-1 which I sent for upgrade.  During the upgrade I used the Adcom. 
I have to say that when I installed the upgraded McC, I was surprised at how well that old Adcom performed in comparison. I may just send it in for an upgrade, too. So, maybe Stringreen has a point.
Those classic 555 and 565 models were made here in the USA! That point alone counts for their excellent sound quality. Pure MOSFET at its finest.
