I'm running the similar albeit, less powerfull Denon 2803 (90 W vrs 110 @ 8 ohm's I believe) and have never had a problem with clipping or having the protection circuit kick in. Then again, the Db level from the M60's at a "0" level on the receiver's volumn control would seem to be WAY TOO LOUD (for me anyway). It does bring up an interresting question though, can anyone please explain why a receiver displays the volumn level as -nn Db and an SPL meter @ approximately 1 meter from a speaker measures something entirely different? Exanole: With the receiver set at -30 Db, an SPL meter at a distance of approx. 1 meter from an M60 indicates ~ 60 Db???
