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

Although I never had the Adcom HT series, I also owned the 555 and the 565 mono blocks. If the 565 were modded (input resistors, caps upgrade, etc), they should be keepers. But I have compared the B&K ST and Sonata vs the B&K AV series amps and there is IME a big difference in that the ST and Sonata series are more extended in the upper registers and are more revealing. You may want to try first with upgrading two channels out of five of your 7400 if you can find a reliable shop nearby.
Perhaps you should contact Musical Design-http://www.musicaldesign.com/MC_AdcomAmp_mods.html.
They perform upgrades on old Adcom's. Maybe they can do some mods to yours. Their prices seem very reasonable, too
Thanks everybody. I think I'll swap some gear in and out before buying anything new. I have an integrated I can substitute and see how the system sounds.

You never mentioned a budget for this upgrade. Which integrated are you using? 
Hi, I listed the budget on the first post.

(Around $700 for a preowned amp or I'll probably look at Integrated like the Nuprime IDA-8.) 

I have an Anthem 225 Integrated in another system I can use to replace the Atoll/Adcom gear. The Anthem does not offer 'preamp in', so my options are limited. It will at least give me an idea.

Thanks, I appreciate your opinion and feedback.
