Matching Amp to Wilson Sophia 2


I recently acquired Wilson Sophia 2's and am enjoying them but I'm wondering if I can do better in terms of amp matching. I currently use Theta Citadel 1.5's. I would prefer a little more midbass (Sophias are currently closer to the front wall than I would like, but pulling them out reduces body).

These speakers aren't overly sensitive (89db) and run at 4ohms.

I also wouldn't mind a little more midrange bloom (I do like tubes!) but don't want to lose anything in the highs.

Amps I've been thinking about: McIntosh, Pass.

Love to hear your thoughts.
Thanks.

Pass should do the trick. X-350.5 worked fine in my setup, but my guess is that XA-60.5 should also work.
I recently heard a mac 275 hooked up to Sophia II's. Sounded great! The amp runs almost as cool as a ss.
Wilson uses the reasonably priced Parasound A21 amplifier to power the Sophia II's at electronic shows with great results. You may want to check it out.
I would pick Mcintosh but if looking at Tubes also consider
Audio research.
ARC Reference 210 for sale on Audiogon would be a killer amp on those Sophia's. Next, but difference sound experience would be used VTL 450 MKII or Signatures for sale.
