I wouldn't want them for the same reason BobM listed,every time
I have played around with multiple gauge stranding in speaker cables or interconnects it has resulted in smearing.
This stuff might work for a power cord in some systems,YMMV.
The unfortunate part about this is that the PCOCC wire might sound pretty good if there were no gauge variations in the stranding and a large enough gauge was used in the strands.
Belkin is building what they think the market wants based on Monster Cables advertising paradigm,the bass will seek the big wires and the highs will find the little wires,yeah right!
