Not a good idea for a speaker manufacturer to put out their own amp. Other electronics manufacturers will stop recommending their speakers and may even bad mouth them. Acoustat made that mistake and look where it got them.
Do you know how long Magnepan has been around for and the value that their speakers give? They have nothing to worry about even if every amplifier company in the world badmouthed them. Any amp company to talk crap on Magnepan would be doing themselves a disservice and everyone knows that except you. Come on, man.
