I can purchase a couple of nice sounding cables for under $100. Room, speaker placement, component matching all matter more. Most situations do not involve throwing $10,000 in cables to get a noticeable improvement in sound. If you spend $10,000 on cables you have more $$$$ than you know what to do with. I heard a pair of $50,000 speakers, on $30,000 of Amp, preamp, and it did not sound good. He had large speaker cables about 1/2" diameter, huge interconnects.
1. The room was crummy. A bose wave radio would have put it to shame.
