| Re: Hearing Damage
As soon as you go above the rated db levels for your speakers the amp requirement go up significantly per channel in order to handle the momentary spikes cleanly. There area number calculators on the web that will show you the extent of this increase.
Listening at 80 db on speakers with a sensitivity of 91db, listening at 8ft away and music with a dynamic range of 10db, it now takes about 5W per channel to cover the dynamic range, increase that 80db at the listening position to 95 and it now takes about 150W to cover the range.
This makes it easy to see why it is hard to drive speakers to very loud levels cleanly.
