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 would especially like to thank Atmasphere for such a great explanation and Charles1dad for his experience with the VAC 70/70 and Acoustats. If I wasn't on a budget I would buy the Atmosphere M-60. All the best
