Upgrade power cable for Quads???

Interesting to note that the speakers are fully charged (at least the 63's are and I assume the newer models as well) only a few moments after they are turned on so why would the PC make a difference in the tonal extremes? Seem to be different schools of thought on this. I find that a better PC does eliminate some noise in my 63's, but I can't say I hear a difference in the bass.

Sometimes it's not WHAT we hear but what we WANT to hear. Although I will not dispute the fact that my 63's seem to sound better with an aftermarket PC because of reduced noise. Did I just contradict myself ?(!*

No question that everyone's experience will be different and everyone hears differently. Stik checking your system page I think you would probably benefit from some room treatments. Base traps in the room corners and in addition treatment of the walls behind the Quads has helped my setup considerably. Hope you’re enjoying your new CJ stuff!
