I have HD & plasma - recommendations on AVR

I now have a plasma TV and HD, so it's time to upgrade the AVR.

I'm currently using a Denon AVR 3300 and it struggles to drive my Hales T-5's in stereo, so I need at least 150 Watts per channel. It will split time between Home Theatre applications and two channel audio listening. My budget is in the $3K range. I'd like to buy used, as I think it will increase my options. However, it must be the latest technology to be compatible with my TV.

I'm looking at Parasound, B&K, Bryston and Arcam.

BTW - The Hitachi 55" plasma rocks!
