I have an H/K AVR520 powering a 5.1 speaker system. THe receiver allows separate speaker level calibration for a dozen different listening modes, including DPLII(music). I can achieve level consistency between, say, Dolby Digital 5.,1 and DVD-Audio 5.1, using the Chesky Ultimate Surround test tones for each. But I do most of my 'stereo' listening using DPL II (Music). I'm wonder how folks calibrate levels for that mode. to make them comparable to other 'surround' formats.
