I have a definitive tech supercube 2000, and am running a cable from my pioneer elite receiver to the sub through 1' conduit tubing that i put in the walls and ceiling. Unfortunately the distance is nearly 50 feet when all said and done, so i purchased a (what i thought was) good shielded cable. After a while i'd notice a static clicking noise that will build up.. and then dissipate.. this was happening daily. I called definitive and they suggested running the sub with a shorter line to rule out the sub as being the problem. So i've done that and the noise is gone. So the problem is obviously something related to the 50' cable.. either interference in the wall/ceiling (it does cross over some power lines - but again.. this is a shielded cable inside a conduit tube). So my question is.. should i try a different 'higher quality' cable? is there such a thing? i've posted the full spec of the cable i'm using below (from monoprice.com) . Any guidance would be GREATLY appreciated! thanks.
CRAP! well i just purchased a newer/better cable (and much more expensive) and am getting the same crackling noise with the new 50' cable... even when its lying on the carpet! soo.. to recap:
good 50' cable in conduit tube in wall/ceiling = problem
good 5' cable on floor = no problem
better 50' cable on floor = problem
the sound sounds like a gieger counter noise.. starting with rapid crackles.. and tapering off over the course of a minute or so.
so what does this mean? its the sub? would a problem with the sub exhibit itself only with a longer cable?
need some help here guys!

The problem sounds reasonably intermittent. How extensively have you tested your setup with the shorter cable? There's always a chance something else could be going on, especially since you've tried two different cables now.
I wonder if some of these might be a benefit in this circumstance on the long cable(s)?
