Are There Any Good, High Power Solid State Amps?


I feel like I'm running low on power with my current 100 watt tube amp, so I'm looking for suggestions. I'd like to try solid state, but I want an amp with an airy, rich tonality. I've been thinking either Pass (love the XA series, but I'm afraid it won't be enough power) Pass X, Krell, Clayton, etc. Can you make any suggestions (new or used somewhere in the $5K - $10k range)?
Thanks in advance.

Sidssp,

Yes, I still have the VR4's (still great speakers...after all this time together!). I've done a lot of work though on the room, by adding room treatment. Don't know why I waited so long to do it!
Sidssp,

Sorry, didn't answer your question. I'm thinking in the neighborhood of 300-500 watts (big Levinson, Cary 500MD, big Clayton maybe?).
Lapierre,

That conditioner is a Running Springs Audio, Jaco. If anything, after I inserted into the system, everything was better......period. No and's, if's, or but's!
