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.

TVAD,
You're right, something doesn't add up here. All I can say is that when I get up to levels around 95db, things get flat, and worse than that, the high frequencies seem to sound edgy....especially piano.
NGjockey,
I also heard the Bryston 28's at 2008's CES, driving some Theils. They were outstanding, and I'd pick up a pair of 'em in a heartbeat at the right price. Retail, they are just out of reach. I've never seen a pair used.
Louis1, what you describe sounds like classic impedance mismatch to me.

There are about a dozen excellent options mentioned.
TVAD,
How do you impedance match an amplifier to a speaker? (By the way, it's Louisl...the last character is an alpha 'L', not a numeric '1') :-)
