I suspect that the triple-shielded Granite Digital FireWire cable I suggested earlier would be likely to provide that particular benefit as effectively as any of the much more expensive audiophile-oriented cables.
I should try the Granite cable then, when I bought the Audioquest a couple of years ago it was the only one I was aware of beyond various stock types.
If the Granite is cheaper and as good I'm interested. I mostly use Purist cable and love them but they do not make a FireWire.
