Having now had this system installed for nearly a year, I am not convinced that I have the best sound set up. I am currently running HDMI for all components, with the addition of an optical feed from the Sky box to my amp, as I believe 5.1 can't be acheived with HDMI alone. I acheive great results from DVDs, but find I have to turn the sound up quite high. From TV alone, amp needs to be turned up to at least mid 40 - 50 for decent sound from front speakers. I believe I need to look at using alternative connections from my amp to better my sound output, but I can't work out what is best from the manual. Suggestions please.
