I am about to purchse some slightly used GR20s, but do not yet have a receiver. Any suggestions as to what the best matching receiver would be? I've read that Denons do not do to well with MA, since it drives the MAs to be a bit too brite? Any truth in this?
The denon/MA combo might not be the best, but if you like it then that is all that matters. On that note, for a fairly neutral system I would match the MA's with a Pioneer Elite, the highest you can afford, preferably the 54 or higher.
I have a Pioneer Elite 45 and a pair of MA GR 20's and am thrilled with the sound.
