What's the better, High Powered SS Amp?

Need a bit more system information, but given your priorities I would recommend Boulder's current offerings and the Classe Omega. Neither is fatiguing for SS and both have the characteristics you described. Good luck!

I gave up on solid state, after my last one, the Pass X-600. I have found much better performance with the new technology of the H2O Signature monos. They weigh a third as much, never get warm, let alone hot, draw just 10 watts at idle, and have brought my system to a point where I feel I can touch the performers.

Before recommending an amp can you provide details on the rest of your system? At least speakers, preamp and source?

This information is very helpful

Are you talking to me, or any of the above? I don't mind.

My speakers are the infamous, but fabulous, 1 ohm Apogee Scintilla. I like nonupsampling, and have a PSA Lambda transport feeding a highly enhanced Audio Note DAC. The preamp is a one of a kind class A, housed in two chassis.

Jeff Rowland 201 or 501 mono blocks fit your criteria. Due to there small size they could easily be positioned behind your speakers if you prefer long ICs and short speaker cables. If not they look very attractive and run extremely effeciently using ICE power supply technology.
