When I used to be in to all this hi-fi stuff, some time ago, (KEF 55.2 driven by a big old NAD C352) I bought in to all the b/s about cables and etc. I paid my way up from Leak 2060s, via Musical Fidelity MC2s.
Nowadays I just listen.
My best man's Leak 1050s, bought about 1970, are still doing great service.
My first attempt at blu-tooth stuff from pc to the NAD failed. Google's best efforts did not work. (W7 Home premium with music stored in Apple itunes)...........(So if there is a working solution out there, cheap enough for a pensioner, I would love to know.
