Meh... need a hearing aid already...
For me, playing with the calculator really drove home what folks here have been saying. I guess I am a visual guy, because I couldn't quite put it all together before playing with the calculator.
One thing I still wonder about is what the danamic range I can expect out of the music I listen to. The Crown website seems to suggest +15db peaks is reasonable
Something Alan Loft wrote in his article about power has stuck in my mind. Music played cleanly as high spls dosn't sound loud.
Put that together with a speaker like the M80 or less efficient speakers in a larger space with music that has high dynamic range, and I can see how you very quickly exceed the power requirements of your average receiver if you want clean playback at reasonable volumes.
As for hearing loss, I wonder if very short peaks 25db above and average listening volume of 85db will lead to hearing loss. Thats a lot different than running equipment for 8 hours a day that generates a continuous 110db of noise.
