I ran my Maxx 2 with a Krell FPB 600c and Spectral DMA 360 and loved both paired with them. The Krell was more dynamic, warmer and had greater headroom but the Spectral was way more detailed and truer to the source. My taste leaned to the Spectral. I've not heard any other amplifier capable of that level of detail, speed or accuracy (Nagra PMA were close as were the Linnn Klimax Solo). I've since moved to Sasha and still run the same amps. Not much experience with the amps you are looking at but figured I'd chime in as I did live with the Maxx 2 for a bit.
ARC Ref 210 or Ayre MXR with Wilson Maxx2
I have CJ ACT2.2 preamp and Premier 350 amp driving Wilson Maxx2. I like the sound of the ACT2.2/350 combo so far, warm and have decent bass, but if I need to change power amp, which amp, ARC 210 or Ayre MXR, a better match for Wilson Maxx2 speakers? I am looking for warm and musical sound, with good detail and dynamic. Thanks.
