Is the HDMI issue the same for any of them (BD, STB), or is it maybe just from an HTPC? Does the power amp use a grounded power cord?

2) The 975 is restricting the volume some how. When I turn the 975 all the way to max, it's not as loud as it should be. I'm hoping a simple setting - I could not find.
When you calibrated the speakers, where did the gain trims come out? Are there any that are very low? Might seem silly, but could try shifting all of them up by 6 dB to see if that helps.
