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.

Be a long, long time before we’ll see X250.8’s for $3K but I’m waiting too so in the meantime my X250 plugs away making beautiful music. Nothing wrong with the original X250 and if you can find one it’s within your budget. Had a X250.5 at home for an eval and it is a better amp than the X250 but it was small and I couldn’t justify making the trade for the difference. X250.5’s pop up time to time but going to be upper $3K to lower $4K I think. If you want to experience a Pass the X250 is a safe place to start and if you don’t like it, it will resale quickly and probably not cost you anything.
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 !
