An integrated that works very well with Magnepan speakers is the Peachtree Nova220 SE. Every great review for this amp was done with Maggie’s up to and including the 3.7’s. It has a built in DAC also. I recently heard it with a Bluesound Vault streamer and Maggie 1.7’s and it sounded really good. The Rogue Sphinx also sounds great with Maggie’s.
Good Luck and keep up the fight!
