Looks like comfortably loud is about 74. But, I usually have it around 67. I'll sometimes turn it up for a song or two, but only to around 80...
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.
