Recommend a Pass Labs amp for Dunlavy SCIVa


I have some really nice dunlavy scIVa's and my tube amps are not cutting it.  I have tried my McIntosh MC 60s and my citation IIs on the dunlavys and they just sound very anemic.  Talked to some friends and I have been advised a nice solid State amp will do the trick.  
I want to go with something in the pass labs used market and was hoping for some advice on what amps to look for and why?
Preamp wise I have the following to choose from.  A TRL, the dude, pass labs XP1, juicy music blueberry, and a very good citation I unit.
Thanks in advance.

Call Kent at Pass and ask him what you need, specifically whether a x150.8 might work.  You might be surprised.
@robmag - If you're short on cash, consider a BAT VK-255SE. 300 wpc @ 4ohms, sounds heavenly (My current amp) and disrespected in the market so usually in you price range.
robmag, for a year, in my 2nd sound room, I used a Crown Macro Reference Studio amp ( the home version which I owned) driving a pair of Sonus Faber Extremas ( the ones with the Kef B139 in the rear ), which were on loan to me from a friend. I thought the combo was excellent. Many components changed during that year in the system, ( including different amps ) but the Crown / S.F.s stayed strong and true in getting the job done. Enjoy !
