Hi GeneI'm trying to figure out if your posting is tongue and cheek. Picture quality cannot improve or get worse with HDMI connections simply by changing your power cables. Either it works (clear picture no sparkles) or it doesn't work at all, or you get sparkles or intermittent audio/video drop outs. It's that simple. Power cables cannot enhance the color or deepen the black levels. If you like how the cables cosmetically dress up your system, then more power to you (no pun intended) but please realize there is NO science behind your claims.
I'm only posting what I'm seeing here in my system. You can try some of these power cables in your system and let us know what you think.
