Actually John, the 50 watts you refer too, would that include the dynamics of the sound? Take a modern action movie with lossless multi-channel sound. The peaks can go well over 50 watts I would think, no?

No; as I stated, the 50 watts were for the max peak of 102dB. At more typical levels, about 1 watt is used.

Ah thank you, I misread. That's good info.

I crank the volume on my prepro at half (I like it loud, what can I tell you ); my SPL meter at 1 meter distance shows a peak of 98dB with music. What am I missing? Either my math it's very bad, something is horribly wrong with my setup or my prepro outputs close to nothing.

AD, I don't know why you suspect that you may be "missing" something; what you report is fairly typical. That 98dB peak uses 10 watts or a bit less for the M80s. The overall volume attained at specific volume level settings varies with the strength of the input from the source materials. Pre-amps typically have a gain(fixed, as is the amplifier gain)on the order of 15dB.

Pre-amps typically have a gain(fixed, as is the amplifier gain)on the order of 15dB. And right you are Sir; thinking about it a little bit, I remember sometime ago I did a little test. I plugged in my old Carver C2 preamp (which I now use as a phono amp only via my prepro) directly into the amps. The volume control knob has a scale from 1 to 10; at 3, it was MUCH louder then then half volume on the prepro. Needless to say, so was the noise. So I dug up the specs on the Carver: MM Gain is 35 dB, while I suspect my prepro is in the range you suggested: around 15 dB. Thank you!
