I have M&K 750 THX with Outlaw 950/7100 combo. I purchase the 7100 with the thought that I could always replace it with the 770 befroe my 30 days was up if it wasn't enough power. Most of my listening is done between -40db and -35db and the loudest I have had my system cranked was -30db.

Glad to hear from another M&K user. Bought my first M&K satellites and subwoofer over 20 years ago before most had ever heard of either.
