Run cable through metal stand?

Actually running the cable in a metal raceway (that's what they're called) can provide additional shielding from RFI/EMI.

The problem is that if the stand is grounded, i.e. if it has spikes that go into a concrete slab-on-grade floor, (not a wood floor) it can allow the cable to build up some inductance. That's why some people use cable-lifters to keep their speaker cables off the (concrete) floor. Personally, I wouldn't worry too much about that since the raceway probably isnt more than a couple feet long?

Would not worry too much, Art. Put them in the pipe.

Although this doesn't belong to this thread I would like to respond to Nsgarch: I think these unscientific issues regarding cables, for example the lifting cables off the ground thing and cable jackets are just hype and a way to make money. That cables could make (big) differences is to many already a questionable issue. To come around with various gimmicks to make those few feet of cables sounding "better" is way overdone (and a bit of hype too in my opinion). Art, I think the theory is right to protect cables for RFI by using a form of Faradayan cage (your metal corridor), but in practice it wouldn't give any difference at all soundwise.
