Warm and Detailed S.S. Amp?

I currently own a Modwright preamp and a Pass Labs X150 amp. I really enjoy these components but, I wish the Pass amp had more warmth in my system. What amps have the warmth of tubes but are as detailed and as controlled as this Pass amp. I can't afford the .5 series of Pass amps. I previously had a CJ MF-200 amp and PV-11 preamp in my system, which was much warmer, but not as clean and detailed. I'm looking to spend about $2K used. Thanks!
