I am a little late to the party, but i just recently purchased a set from Bernard at Charisma Audio in Ontario. I have them paired with a Sugden IA-4 pure class A amp, and i could not be happier. They are a very musical and focused speaker, the clarity is insane. I compared them to my Dynaudio special 40’s, and there was no comparison. The 311 is a far superior speaker in every way. Mind you the 311’s were $3000.00 more than the S40’s . I listen to a wide variety of music, but mostly jazz, blues and classical. These speakers pull out annunciation far above anything else i have heard. The more you toe them in, the bigger the soundstage gets. i have an extreme toe in right now, and it works in the environment i have them in And the musicians move all over the stage, its hard to explain. As for the Magnepan’s ? I watched a review this morning that claimed you need a 500 wpc amp to drive them otherwise they sound distorted.
