I power my MG-20's with a pair of Threshold SA-1's on the bass panels and a pair of Pass Labs XA-100's for the midrange/ribbon tweeters. If it's in your budget try to biamp your 20.1's and the Pass Labs X-.5 series or the XA-.5 really would make them "sing".
Despriately looking for amp for Maggies 20.1
Blew a fuse on AR 110's krank speakers to preformance levels most of the time
using a Anthem 5A for surround speakers. now thinking of bi-amping or 500+ mono blocks I need a series of opinions of people who actually have owned them and driven them
