Please recommend a high-powered SS amp

Audiogoners, many thanks for your suggestions. I guess I should elaborate. And no, there's absolutely no show-off happening here. It's just that currently I'm driving my Proacs with an integrated SS Plinius 8200 MkII (175W rms/ch). Now beyond a certain point there will surely be clipping/distortion, which will be less at the same volume levels with a high powered amp. Doubling of RMS power takes the SPL up by 3 dB, so I gathered that a tripling would take it up by 9 dB, which is kind of a substantial perceptible difference. I want to be able to fill the room with high volume sound (at certain times) without the clipping/distortion, and I think higher powered amps may enable me to do that.

Thanks again. First things first - they are Proac response 1SC monitors; I think theyre 87 dB efficiency. I usually do not play them at high volume levels, but there are days when I want to play some loud blues or rock and on some CDs I find I need to take the volume beyond 60% and that dont make the speakers sound too clear. Of course it could be the room too.

Fafafion could you elaborate on resonator-type feet; I have no idea what that is.

And dang! that was bad arithmetic. Thanks for the correction Larryi.
