It’s quite normal to play movies louder (seemingly louder per the volume control on the HK) than music. Movies and such have very dynamic sound. Meaning, lot’s of variation. With music, the sound is much more consistent.

My 7300 and M80’s with the EP 600 is usually around – 15 db when I watch movies and I sit only 9’ away from the boob tube and it’s about 75-80 db’s. With music, -30 is about 80 dbs.

Plus, although an insignificant increase, in two channel mode the 7300 has a few more watts.
