Recounting a recent incident:
I loaned a XXX a some interconnects/speaker cables to a potential customer. The system comprised an Ayre CX7, Blue Circle BC3 pre, Sanders power, and a Harbeth SHL5. Initially I thought that putting in the XXX should open up the soundstage and bring the music into better focus. When I heard it, the dynamics did appear to be restricted. This customer was using some exotic python thick powercords. So we switched those to AM powercords - Sorcerer, Illusion and PowerDrive on the amp. Immediately the music began to flow much better, coming from outside the Harbeths (which I had always thought exhibited a boxy coloration). The transformation was amazing.
So consider this when you try to change one component in your system: what you are hearing is the combination of the sum of everything there, not just the last piece that you changed. It is possible that this last piece just shows a shortcoming somewhere else - yes YMMV.
