'think it will buff out?

It seems that 0.9 doesn't have the 24 bit padded to 32 option any more and doesn't work with my sound card at 24 bit fixed (M-audio Revolution 7.1), only seems to work at 16 bit fixed.

It strengthens the cable (prevents the cable from tearing from tension).

I wouldn't be worried about the magnetic field around the sub but instead the potential damage caused from the physical vibration of the sub...
