if some people think they can hear differences between different interconnects and speaker cables then that's fine, i'm not going to tell them they can't.
but i can't here such differences, and as many blind tests have shown people can't pick out different cables/interconnects, and i've yet to be given any explanation by anybody on here as to why/how these differences might be there.
so my advice based on the above is to buy the cheapest as they will imo sound every bit as good as more expensive interconnects/cables which have simple wire at their core, the fancy coating/sheathing has no relationship with electricity and therefore is irrelevant.
just my views...
(i have no wish to argue with anybody, or to be rude)
