Oh man.

A very inefficient speaker will convert 1 watt of power into about 85 decibels at 1 meter. 10 watts per channel should be way over reference level in any reasonable sized room.

It's about gain, not available output.

And sure, I like power too. But it's more about play time than real listening. I mean, I own 4 Carver m1.5t amplifiers among other things. Power is fun, and it sells I suppose, but let's convert it to dbWatts:

1 watt = 1 db watt
10 watts = 10 db watts
35 watts = 15 db watts
65 watts = 18 db watts
100 watts = 20 db watts.
125 watts = 21 db watts

Those are very rough approximations, but they're close enough to show the point - after 50 watts or so diminishing returns set in with a vengeance.
