I would certainly appreciate suggestions for where to start looking in
the power amp arena as well. A good solid 2-channel solid-state amp
with plenty of power and better sound than the Adcom GFA-555 would be
the requirement here. I'm willing to spend up to $2000, or perhaps a
bit more if there's a good reason.


Since the preamp/tuner is obviously defective, and not worth fixing, you
should replace it ASAP. Since Adcom has satisfied you for like a decade, and
they still have a good reputation, why not replace the old Adcom preamp with
a new Adcom preamp?

According to
http://www.audioadvisor.com/store/mf...g=ADCOM&Page=3 ,
the current Adcom products that seem to match your needs are the GFP 715
and GFP 750. You can read more about them at
