why do people feel the need to buy expensive cableBecause in some cases, they sound superior.
In my system, I use a combination of PCs. 2 that were custom made at $175 each and the rest Nordost Valhalla, High Fidelity and Shunyata Sigma.
I build my AUDIO system base on SOUND QUALITY and NOT status, measurements ... I use my EAR and buy what sounds the best!!!
