AEJim - surely u have used 22mm copper.pipe - is that not.u use in yr top of the range units?
Actually, in our top of the range drive units we use Aluminium cable!
But alas, it's still very thin... People forget that for all the ups and downs of cable debates once you get inside a speaker you generally have 100 feet+ of bog standard copper (or indeed aluminium) cable in the drive unit voice coil (for our Radiance and Reference Series' you can double that because they're dual-wound on both sides of the former). No matter how flash the internal wiring between crossover and drive unit may be you still have to use a lot of relatively thin wire for that voice coil to get the required winding.
When it comes down to it If
you think the cable between your gear has a drastic effect on the sound then buy something you think will make your system perform at its best and be happy with it, if not then just use something thick enough for the required length and you'll probably be ok anyway.
