Small vinyl system..Thiel, Musical Design preamp, + ? Acurus amp?

So I have the bug again of system building...
Small vinyl 2.1 system in my reading room, 12 x 12

Trying to utilize my Musical Design preamp I've had in box for 15 years

AT 120 turntable 
Thiel 1.2 speakers
PSB sub...
Music Design SP 2B tube preamp

? 
Acurus A250 amp , used. <<<<<<<. questionable to drive Thiels
Can be had for $400-500 used, and want to stay on this area.


My concern is matching preamp to a power amp.
