Sometimes zip cord is better than high end cables, certainly compared to the defunct High Fidelity Cables. Cables require system matching, especially interconnects. I’ve noted the vast differences between my friend GroverHuffman boutique patented power cables with a 2 hour build time (complicated EMI/RF materials and construction as well as the manipulation of the wires themselves) versus Pangea mass produced on a $1/2 million system my electronics engineer neighbor was using, refusing until he heard just one (of six in his system) fundamentally alter and greatly improve his system, for cheap ($750 6’ and bought 6 for his system).
Digital cables are causing me the biggest problem though which really they shouldn’t. Also note that some high enders have replaced their $18K speaker cable with Silversmith Fidelium cables for only $1,300. So, it is both quality and system dependent decision and takes some quality listening and one’s personal listening preferences (sound and music) to determine which cables fit best.
