Can the NAD C740 receiver (35-40 watts) drive M60 speakers? My room is 13 x 16 x 9 feet and I listen to mostly jazz and some classical at moderate listening levels. Thanks for all replies.

I ran my M60s on a 60-ish watt receiver playing all kinds of loud rock and never felt I was short of power except when I tried for that "wall of sound". For your application I expect the receiver would be fine. The difference between 40 watts and 80 watts is only "turning the volume control up 3dB" anyways.

I assume you have had some speakers hooked up to the NAD now -- are the M60s much less sensitive than those speakers ?

Easily. I run my 60s in a similar sized room with a C320BEE (50wpc) and it has been rock solid thus far. Is there a noticeable difference between 35 and 50 wpc? Probably not.

Don't know the specs of my current speakers, but now I am forced to out myself. They are EPI 100s (dare I say Consumer Reports best buy from circa 1974). Think I will notice a difference????!!!!!

I do remember the EPI 100s quite fondly; they were my very first set of speakers. I have had a few sets of speakers since then, now I have the Axiom M80s. I really don't think the EPIs are in the same ballpark as the Axioms. You will be discovering your music all over again

Cool. I always liked EPI 100s.

I believe you will find that the M60s will play a bit louder than the EPI100s at the same power levels, so if you are OK with the volume levels now you will be more than OK with the M60s.
