Well Im buying one of those Mark Grant cables and was just thinking how it was the first time I would be able to compare a OEM patch cord to a proper cable. Every piece of kit I have bought has meant getting a proper interconnect so Ive never used a patch cord (bloody hell maybe they are better ). Then I thought, giant subwoofer putting out so much bass, that, during loud scenes, has me and the missus hiding under cushions. Fit new cable. Oh yes, thats so much better, we need some thicker cushions How Im I going to tell the difference ? Its easy with most equipment; image , clarity etc. But a sub lacks image, it shouldnt make its position known.
