Long story short: My NAD 2600 blew up from static electricity. A friend
who is not an audiophile has offered me an Adcom 555 Mk 2 really cheap
for $150.

The rest of my system is: Teac Esoteric P-10 transport to PS Audio sl3
D/A by Illumanati cable. McCormick Line Drive Deluxe passive pre. NHT
2.5I speakers bi-wired. All analog wiring is Tara. Also have analog
components & a Pioneer universal SACD player. Listening comments below
are with the digital front end.

I just plugged the Adcom in (I'm told it hadn't been used much lately) &
have 3 concerns. With all 3 concerns, my question is, "Is this normal
behavior for an Adcom amp?"

1. The heatsinks are quite hot from playing 4 songs at normal volume & the amp also runs really hot just idling.

2. There is some light hiss in both channels, even with the input muted.
One channel has more hiss then the other

3. The amp is quite a bit brighter then the NAD. It may need to warm up
for awhile (though again, the heat sinks are almost too hot to touch)

I used to own an Adcom GFA-1A amp.

Yes they run hot. At least mine did but that never bothered me.

In its day it was a good amp, but it is really dated.

IMHO it is not an amp worthy of the rest of your system.

After listening, I 100% agree, but my budget isn't what it once was........

I think I am going to look more into getting the NAD repaired.

If it's to costly you might want to take a look at Emotiva amps,I have a XPA-3 and love it. I will say I never heard a NAD amp but have others and the EMO is a steal for what you get.......just a FYI
