Their Karma RCA cables can lick my ball sack. I had one end fall off from gravity! It was was hanging while I was holding the other tip and then it just broke off. The heat shrink tubing wasn't even touching the insulation on the cable so the solder joints were the only thing holding the head on. The weak *** joint snapped. I replaced the cables with some Stinger Helix (cheaper than the Karma) and the quality is MUCH better on them. I also had a noticeable amount of reduced noise from switching to them. I'll never buy anything from Knu again as I have yet to get anything from them that impressed me.
