Ordered from OSD's website. Have used Emotiva before but not w these speakers. Will post back if something good/bad happens. I have it set to auto-on when signal is sent, has worked perfectly. Only issue was a ground loop problem w the receiver, but it is a common thing. Connected the receiver radio ground to a chassis screw on the amp, fixed it. Wish amp had a ground screw, but thats my only nit so far.
