I don't have an answer, but I do have a question for this topic & some suggestions.
I have a pair of BK subs on their way to me in the near future & need a new pair of sub cables. I will be using their Neutrik connector for music, so sub cable/LFE input will be for home theater only (which is why not looking to spend huge $ on a pair of sub cables).
Seems alot say any old cable will do but I have first hand experience that says otherwise. I origionally had a Monster sub cable bought from my local big box store. Probably paid $40 for it (which is probably $35 too much). I switched to a Taralabs sub cable (just their basic solid core, not RSC conductors) because I was buying some of their other cables & got a good deal on it. I swapped it in, not thinking about it, tuned on the music some time later & something was up. Sub sounded better & stopped making a strange noise that it use to under certain circumstances. Then I put two & two together & realised it was the cable that changed.
So being I need a pair of cables, I've been looking at Blue Jeans sub cable, Audio Advisors Black Thunder (Audioquest ends & cable, terminated by AA) & Audioquest Sub-1's. Their cost for a 10ft pair would be ~$50, $160 & $300. I'm sort of leaning towards the BJC cables as I've used their cables in the past & have been very happy with construction & performance for their cost. Don't mind spending abit more if I will hear actual benefits but I'm thinking at 3 times the cost, not sure the Black Thunder will perform that much better?
