Help! Trying to pick an amp/preamp for an Acoustat 1+1s

I am picking up a pair of Acoustat 1+1s and need your advise on powering them.

I would like your opinions on these:

Pass Lab 150 IN

Rogers High Fidelity EHC-100 K88

Synthesis Roma 510 AC Int

I am also interested in a VTL 225 but would need another preamplifier.

Thank you in advance,

I must say I was very impressed with the sound I heard, considering the age of the speakers. He also had mentioned that he thought they were 82 or 86db efficient .

Just yesterday I went over to my buddy's place. My buddy had my LSA wasp class D ...125 wpm into 8 ohm amp at his place for 2 weeks. . He has the acoustat, not sure of model, about 7 feet tall and maybe 12 to 15 inches wide. His room is approximately 17 ft by 21 feet. He had been using NAT mono blocks, but couldn't get them to drive the acoustats. His jaw dropped when he heard this amp with his speakers. he subsequently, spent many hours in the music room. I can only guess that the current the amp produced is what drove them satisfactorily.
