Hello, I have an issue with my Denon AVR-791 and the headphone volume. I find the volume is very low. I have tried different surround modes and its still low. Im not sure if this is a limitation of the headphone or a misconfigured setting in the receiver. The headphones are sony mdr-150 studio monitor headphones. I dont think they are 5.1 or 7.1 certified so that could be the issue? Any ideas? Thanks!
