For your consideration is a Parasound HCA-750A in EXCELLENT condition, except for a small "ding" right above the power switch on the edge of the faceplate, I have been using this amplifier for several months now in my system with great results.
I have powered Polk LSi9 with this amplifier with ease... do not let the wattage fool you - it is underrated and clean.
This amplifier is capable of being bridged as well.
See below for specs -

I so want this for my center, going to have to try and sell my Onkyo m-5200 first, we will see what happens. I'd jump on it now, but I just dumped money on the other hobby. If it's still around when I got the coin I will take it. If it sells before then, well, there are more fish in the sea. In the meantime GLWS. To you noobs with Adcoms this is the way to go, you will not have the slam of an Adcom, but will gain detail spades, even in the bass department.

No problem man, let me know!
This blows Adcom of the time period out of the water, no doubt about that! You speak the truth!- Not Tom ::::::: Any system can play Diana Krall. Only the best can play Limp Bizkit. -
BUMP!
Tomorrow this bad boy goes on the GON!
Thanks!

Very nice amplifier!

Is it still available?

I believe for right now I have decided to keep this little monster around!
