Hello everyone., And thanks for replying...
yes, the setting of the volume control is higher on the Sony than it was on the HK for the same volume.

Since the HK does not have Dolby ProLogicII or DTS:NEO6...is there anyway I can use the Sony STR-DG600's digital decoder to output the digital movie signals like PrologicII or NEO:6, and send it into my HK receiver? since my HK does not have those modes...
