not just h/k but also onkyo and dennon I've see in posts that the m-80's were triping off the auto-protect and there was even one guy on this board who listened to me after trying the half dozen other suggestions and wrote back to say "YOU WERE RIGHT' but maybe you're on to something with looking for a receiver without the auto-protect....ever see an amp light up from pushing it to hard? It seems to me that alot of people on this board protect the m-80's from this topic when it is very clear to me that most a/v receivers of today don't do well with the m-80's.no big deal but people who do have problems with this issue seem to get more of the run around then help.its the power supply,the wall plug,you're cabels.etc.etc.etc.its simple trade up for a pair of m-60's or get more power. oh and sorry to hear about you're inflamation........
