Watt Puppy 7s/Maxx 2s

Watt Puppy has become wildly overpriced. Also annoying is their re-negging on their forward compatability promise. Beware!

Depending upon your room and taste, you might also consider JM Lab or Rockport. I'm not sure about compatibility of the other tube amps you mentioned with the Wilsons, but Atma-Spheres have been used very successfully with them, as have Lamm. I agree with Aceto's comment about Watt Puppy forward compatibility, as 5.1 -> 6 -> 7 has required a new purchase each time instead of being able to retrofit.

I use the Atmasphere MA2 mk2.3's with the MAXX2's and can attest that the combination is everything that I had been hoping for in 2-channel music reproduction.

I have friends that own the MAXX2's and use them with either the Lamm ML2's (18w) or the new Audio Research 610T's. There are likely a number of different amps that will match well with the MAXX2's, however, the best bet would obviously be to try several before deciding what works best for you.

aceto, overpriced indeed.

Definitely overpriced, unless you just like to look at your speakers.

The Maxx2s, though well review able to produce beautiful music, are unfortunately blown out of the water by VMPS RMx at about $12K a pair. But Wilson wins the visual honors in that pairing.
