ok, "you are wrong" was not intended as an attack, as much as a seeing the light kind of thing with cables
Hallelujah! Hallelujah! Another saved.
I see the light too! However, my philosophy is somewhat different: any piece/group of equipment that improves by 20% with change of wires (no filters - some cables are actually filters which would be different) is either badly designed or something is already incompatible/broken in my book. So for sure a cable can make such a huge 20% difference but this simple fact points to another problem somewhere else. (remember an IC or cable is just wires).
So in my religion audio equipment should work well with any appropriate interconnects and cables and if it doesn't then I get worried about the short comings of the components or their fundamental compatibility with eachother.
