I've tried using the same interconnects and speaker cables from several manufacturers, and have had the same result with all except one: too much of a good thing. All cables inject some chararcter (or "color") on the sound. I find that if I insert company X's interconnect I may really like what it does to the sound, but when I add company X's speaker cables on top of the interconnect, I get more of company X's signature on my system than I want.
I suspect, but have not heard for myself, that if you get in the stratosphere of cables they become neutral enough that the "too much of a good thing" phenomenon wouldn't occur. I'm not willing to spend quite that much money on cables, though.
Note I'm only talking about speaker cables and interconnects. Power cords are "a whole other" subject of discussion and debate.
