Was just curious...with the way my Onkyo TX-SR600 speaker calibrations were made (they are above "0" dB for each channel), does it sound normal that during playback of most Dolby Digital soundtracks on DVDs, I need to bring the volume beyond low-to-mid "40's" on the Onkyo's volume control in order to reach a comfortable, rather loud (but not too loud) listening level? DTS soundtracks dont usually have to be that high; they can rest comfortably below 50. But some DVDs I need to bring to even above "50" on this receiver's volume to feel comfortably immersed in the film's soundtrack. The receiver, as most know, is rated at 80 watts x 6. Does this sound normal?
