When picking cable what properties of the cable should one look at for good shielding? Many show a rating of capacitance in pF/ft. Is this relevant? If so is a higher or lower number better?
I've always gone for the best shield coverage and quality and looked for a low capacitance (measure it yourself) all in a flexible, soft and decent cable. Unless your runs are very long or your sources are low level, high impedance (phono etc) you don't have to worry too much at all.
No need to obsess on pF per foot at audio frequencies and short runs using line level sources IMO. Lower pF is better, but not if it comes at the expense of less/poor shielding.
Lots of cable these days is crap. Heaps of CCA (copper clad aluminium) masquerading as OFC, lots of tinfoil instead of 100% copper shielding and dubious quality dielectrics in coax.
Maybe an proper RF guru (Don) can weigh in and advise.
