Sutts (and others reporting 'haze'), how is your power? I modified a power strip with a small (< 1 uF) high-voltage (400V) film capacitor across the hot and neutral lines, and noticed immediately a reduction in 'grain' and 'haze' from my Hafler amplifier, which uses MOSFETs. My approach is very similar to the original Shunyata Hydra-4 power conditioner, which only uses a single 0.1 uF isolation capacitor across the hot and neutral of both duplex outlets in the unit. (Note: DO NOT try to build one of these if you don't have electrical training. AC power KILLS.) This very rudimentary power line conditioner made a startling difference in my system.
It's possible that what is being described as 'haze' is the result of dirty power.
