This type of thread can act as a warning to any newbie thinking about going down the audiophile path. The level of audiophile nervosa that can arise in a purely subjective paradigm is really something (virtually anything you do can be perceived as "changing the sound" so careful about touching anything in your system and don’t forget to hold your rosary beads!).
Audiophiles who talk like this about cables would have a heart attack (if they thought consistently about these things) watching the type of cables and how they are moved and strewn around in making the recordings they cherish.
Imagine if the pros believed all this stuff. "Hold on guys, Eddie just moved his cable, we have to hold off another day for recording until it settles again."
Yeesh.
I move my cables around all the time. ALL the time, because I’m often switching them between various speakers I own. Or merely re-adjusting them along the floor (they are in a fairly high traffic area in our house). Does the sound ever change, the soundstage collapse, the sound get duller etc? No. Never.
But then I guess I haven’t spent the mega bucks on high end cables that can’t handle that type of abuse ;-)
