I have a pr. of Maggie 1.7s and drove them for a while with an Ayre V5 xe ss. amp @ 150w per side @ 8 ohm and 300w per side @ 4 ohm (even used, probably a bit more than you want to spend for just one) Even though I liked the Ayre very much, I finally settled on a Rouge Cronus Mag. II, a 100w per side, integrated tube amp and am most happy. With the Maggies, I like the sound of the 100w tubed Rogue even better than the 300w ss Ayre and at half the cost. I am using just a single amp to drive the 1.7s and it drives them very well at any volume I care to listen at, although you may need more if going to the Maggie 3.7s. In all I have to agree with others that tubes just sound better on the Maggies.
Good luck with your quest
