Budd, my thought on your question about your 1014 driving M80s is to remember that it has the THX Select certification. Although many poo-poo this as a mere marketing tool and grossly over-estimate the cost($5 or so per unit is my understanding), it includes driving a 3.6 ohm load and is useful as an assurance of amplifier capability. It's likely that your 1014 would be fine with M80s.
