Chadnliz:
Yeah, I used to think the same way....now I let my ears be the judge. The conclusion I've arrived at on my system is this: the more resolving the entire system is the more everything matters....especially cables. Three things I've notice w/ the Synergistic powered power cords on my Quatros:
1. Better overall coherence from top to bottom.
2. BLACK silences...absolutely no noise.
3. At least one octave deeper bass.
IMO, you will be hard pressed to spend money to equal or surpass the above benefits (with nice speakers such as the Quatros).....be openminded on this matter -- you won't regret it.
