Hissing noise usually is because of grounding issue. Are all your components grounded properly? Did you change the power source? Have you connected the Zephyr power conditioner?there's lot of hisssing noise in speakers when u put ur ears close to it and when i play only with onk 807 no hissing is there
and sound is more alive and open don't know why but i don't like it i guess
Thats strange. Are the settings in the AVR correct? Are the speakers out of phase?i only test amp in stereo mode so if stereo performance is like that i'm afraid ht perfomrance will suffer too its like someone put somekind of clothes on my speakers to cover the sound and sound is not breathing properly u know what i mean
You don't need to wait for your projector to test 7.1. Connect it to some other TV in your home via an analog connection from AVR. Use the TV only for OSD - to navigate through the Blu-ray\Source Menus and test the sound.
All the best mate!!
