Thank you Grant, I rest my case. yet mapleLeafs3 was a 'good' theory, in that it lended itself to being proved true or false. As such, even if one doubted the veracity of the PF specs, one could presumably waste some perfectly good money and take a Purist wire apart to verify that the wires are made from utility grade lamp chord. Mapleleaf3, want to give it a try?
