Sub Cables? normal or specialist?

[admin_exported]

Has anyone noticed a marked improvement in sub sound when using a specialist sub cable rather than a normal digital coax? Just seen some on play aand didnt even know they existed!

any thoughts?

Not a digital coax, but a standard interconnect is what's required, and the only real requirement for the longer runs usual in subwoofer implementations is decent shielding, as the longer cables can tend to pick up hum which is then amplified by the sub's 'engine room'.

It's also worth taking care with the positioning of such cables - try to make sure the sub cable crosses any mains cables it ensounters between receiver and subwoofer at right angles, rather than running alongside them, but best of all keep it well away from any mains cables, as these can be a source of interference.

Thanks for the reply Andrew, interesting what you said about cable positioning, ive got all my cables (speaker, interconnects, power leads) enclosed in the same hidden cable tidy and all running in the same direction. Ive been getting background white noise, buzzing from all speakers some times, noticed it more during chapter changes on dvd, could this be the problem? also done some net research and heard about ground loop issus (although i dont know what that is)

any ideas/help?

If you want to hide your cables in such a tidy, I'd use two - one for signal cables and a separate one, kept apart, for power cables. Yes, I think your current cabling configuration could be causing, or at least exacerbating, some of these problems.
