First thoughts on Boston A7200 Amp

1. I'm not a hardcore audiophile and my impressions might not meet your expetations, so be easy on me. I use my gear 90% for HT.
2. I did join this forum a long time ago and haven't posted much, not because i didn't want too but because was too occupied. And every time I came in to check things out it end it up costing me, 2 years ago I was looking to upgrade my subwoofers with Polk and end it up buying SVS, now it's the separates.
I was looking into the outlaw 7125 and this deal came along $815 shipped form onecall with no interest for 18 months, so I jumped on it.
I have the A7200 for a week now, it's heavy 70lbs plus and well built.
It doesn't get hot or warm and no humming noise or unwanted sound gets to the speakers.
I noticed immediately that my front L-R speakers and also my surrounds have come to life, my soundstage is fuller not as harsh not as bright either. I was able to pick up a few more details on the sample DVD's that I played.
I'm still evaluating it but so far I'm very satisfied, some people say it takes 1-2 weeks for the gear to break in, will see what happens.
The only other amp I had was the M-282 which I was using for the back surrounds, compared to that the A7200 gives me a fuller and cleaner sound.

Great score Peteran...:)
What are the specs on that make and model?I never had it like this where I grew up. But I send my kids here because the fact is you go to one of the best schools in the country: Rushmore. Now, for some of you it doesn't matter. You were born rich and you're going to stay rich. But here's my advice to the rest of you: Take dead aim on the rich boys. Get them in the crosshairs and take them down. Just remember, they can buy anything but they can't buy backbone. Don't let them forget it. Thank you.Herman Blume - Rushmore -
here are the specs from the pdf manual.

Pardon me if I'm wrong, but isn't this for two different models?

At first I got confused also, apparently they are weighing different aspects of its output.
Maybe somebody with more knowledge can explain it better. -
It's comparable to the Sherwood Newcastle A-965.
