Using Zu Wax Biwire cable ($1000+ new, bought used at $400) on sub $5000 systems did not reveal notiecable difference from $100 single wire from Signal cable.
My current system (amp, preamp, cdp, turntable, speaker) is a bit over $15,000 (if bought new ;-), and I start feeling some differences. The biggest difference was with ClearDay shotgun silver speaker cable ($240 new). Brighter and more detailed sound. (Some may not like it though.)
However, I still havebn't noticed any significant differences, if any, among several sub $200 cables (power, IC, speaker) I've tried.
