Wow, those Premium cables from Monoprice are very reasonably priced, even cheaper than Pythons, and look quite sturdy. Thank you for pointing that out. I will need to cover 6 channels, to upgrade everything, so that will keep the price in check for me.
I saw several 5-star reviews about Python cables, saying they are substantial and well-made... But I'd rather ask here first
I'd like to ask also - are twisted-pair cables in common use with high-end home audio users? Monoprice premium cables are coax, from reading their description - is that superior to twisted-pair?
