60db in the 13' x 13' room I use is plenty. that's about No4 on the dial. Any more than about 70db and you can feel the base through the sofa :^)
How loud are you typically listening?
Typically 75 to 80dB. Really loud is 90dB and I'm never over, and I mean never, 95dB. I'm using a professional SPL meter, C weighted, slow response. Just curious.
