Don't forget to add in the distance you are listening in the formula like the online amp calculators do, but either way J.B, you listen far too loudly for me. I listen at about 70-85 and peaks hit around 100.
you say i listen far too loudly; the levels i listen to is the same as in good cinemas.
maybe one reason you can't do it (too loud) is that your room is not treated? or maybe the neighbors.
i had forgotten to talk, in my previous post, about distance from speakers to MLP; in a small room, i think it should be about 3-4 dB less for each doubling of distance. large rooms lose more,until in open spaces it's 6 dB's.
