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.

In my search for a new amp for my Verity Parsifals I spent a day listening to the ARC Ref. 110 with the Sophia II's. It was nice but was a bit forward in the upper mids and a little light in the base. This was with the ARC 26 pre and ref phono, clearaudio TT with concerto cart. It was nice but I have heard the sophia's sound a little more solid on the bottom than this set up. Stunning build quality on those Wilson speakers.
I had Sophia I's and tried a bunch of solid-state and tubed amps, and IMO, tubes are the way to go with these speakers. Unlike the Watt Puppies, the Sophias are an easy load and I thought they sounded best using high-powered tube jobs from ARC, Conrad-Johnson, and VTL. Most solid-state amps just don't bloom and soundstage well with these speakers, at least the Sophia I's. The only SS amps I have heard that do at least some of this are Essence amps, difficult to find.
I heard the sophia's with a Mcintosh MA7000 and it was amazing. I love the silky warm sound that the combo has to offer. Also look at musical fidelity and plinius separates.
