I tell ya what a few years ago I owned a Pioneer Elite VSX-32 reciever that was THX Select 2. I ran low sensitivity Polks and at -10dbmv it would go into protection. It infuriated me. I put up with it for a few weeks than returned the reciever. Too bad cause I loved the way it sound. After I than got an Onkyo NR809 and I've enjoyed it now for 3 yrs. Sold the Polks.
Moral of the story just cause it's THX Select2 doesn't mean it can play reference.
