I don't usually listen at levels above 90 db. 1 watt at one meter, 90 db sound level = 90 db efficient speakers. I think.

I have some amps with big beautiful dials. Most of the time while listening to music at normal levels, the amp is ticking over at less than 0.5 watts.

Enjoy the Music. Trust your ears. Laugh at Folks Who Claim to Know it All.
