I have used Krell Evo 403, Ayon Spirit III, PBN EB-1 "Super Amp", NAD M2, Cary 200.2 and some custom 12 watt Triode tube monos. For fun I even tried my trusty old NAD 3020.
The V's are a clear view into the source. The better the amp the better they sound. The NAD 3020 didn't suck, it just sounded a little dated and dry on top. The M2 had the fastest bass I have ever heard in my home. The Krell Evo was mind blowing but costs $50. per month just to run and the heat will kill you. The Ayon was the best value and had tube magic. My long term "reference" is the PBN EB-1. It's on the expensive side, but has a sweet holographic soundstage and sounds great even in cool running "low bias" mode.
I may try a First Watt J2 next.

Cary 805's for the winter would be fun too
