Class D with low-end drive/slam

I'll go out on a limb and say the BelCanto ref1000m amps I use are world class in this regard. They will run a tad beyond your price range even used though.

Some of the other less expensive BC amps may do quite well also I would expect, especially if used with a good SS pre-amp.

Wyred4Sound is another similar line that is more like than unlike the better BCs according to reports and would fall in you price range.

Definitely go for as much power and current as your speakers are capable of handling, but be careful that they do not break up as a result of being overdriven as they do.

I've found the 500 w/ch Icepower ams to be exceptionally good mates with both the Dynaudio and OHM Walsh speakers in my system.

Thank you. That'a very helpful. 500 watts Class D is a lot less expensive than 500 watts SS....This is for my "frankensystem."

Tommy from DigAmpCo often has demo gear for a great price.

I think the actual review unit from the Affordable Audio Review http://www.affordableaudio.org/aa2010-09.pdf is currently available.

I've heard plenty if ICE amps w/ their switching supplies and they don't compete w/ the Digital Amp Cos proprietary Class D technology and massive linear power supplies.
