I actually received and set up the M500-II today but have only streamed through it via my Fire tablet. So rar no problems. I've run through the menus changing filters/colors etc. but have not found any real benefit there. I also hooked it up to a set of Elac Navis which are newly arrived and it's a great combination. Comparing directly with Elac UB52's, the Navis sound "bigger, warmer, more complete". As well they should. I only mention it because I had some system matching worries. But no, they're fine. I am very pleased with the sound and, for the first time in a long time, I have imaging suffcient to having the speakers *disappear*. Oh yeah, I'm happy.
