I am in the same boat as you becuase I want to run a pair of maggies. From researching here, I have already bought a pair of classe CAM350 mono blocks to run the Maggies which I have not bought yet. I currently have 230 watt tube amps which are not going to be big enough based on what is said here and audioasylum. The 3.6r need a lot of current in a large room which most tube amps can not deliver. There lots of threads here on magnepan just search.
amp and pre for maggie 3.6
I am looking for some experienced imput . I listen to mostly non acoustic music, I do like to play it louder than quieter. can spend up to 4 k on each . I have a listening room about 20 x 24 with a sloped ceiling. I do listen to vinyl first and foremost, and would prefer something made in the last 5 -6 years . I am open to bi amping using my old A R C d 110 on the bottom and possibly something tubed on top . thanks for your feedback !
