alright got this installed today. When I was done installing it I decided it was worth it even if it doesnt improve a thing as it helps with alot of cable cleanup in my system...that and the surge protection are worth it.
Music - I am probably imagining this a bit, but I think I am getting a bigger soundstage...or maybe it is clearer imaging, as the one thing I know for certain is that the bass response is much better and there is a detail in the mid-upper range I was not getting before. Slight difference...in that I dont think it is night and day, but it has alot more seperation of the instruments than I had before. The analogy of the music jumping out at you is dead on as well.
Video - Dont notice much difference on SD programming. HD however has a change...seems to have a much better color definition...colors are definitely more vivid than they were before. DVD...minor video change, I am seeing some of the same effect as I see on HD, just a smaller scale.
Overall, well worth my $130 price after rebate...pretty happy I got it...for reference I was using a monster surge protection strip before...
