Parasound 1500a 200X2 @ 8 ohms and 315 watts @ 4 ohms..used go around 500.00 or so. Weighs 43 lbs..if you had about 650.00 or so you get a used parasound 2200 which is 250 watts x 2 @ 8 ohms ..
I bought a Rotel RB-991 for around $600 off Audiogon. It's 200wpc x 2. I'd like to tell you what an improvement it's made, but some jackass at UPS dropped the box during shipment, and it's being sent out for repairs.
I have a GFA-555II that I bought in 1991 and have used it every day without problems! It is rated at 200 wpc into 8 ohms. You can usually find them at $400 or less at Audiogon.
