I'm having a discussion with the bloke wot repairs me hi fi (I only play with the "hit it wiv a hammer" stuff) at the moment and he is giving it large about my needing to use at least 79 strand speaker wire for the HiFi (OK, I play it loud, but not 500wattsperchannel loud) - and more obviusly suspiciously to me he is giving it large about the need to use better quality "interconnects". I don't get it. The signal currents are tiny so why not just use flimsy phono-to-phonos?

I understand, of course, the need to use 4mm cable for stage subs that I am stuffing 3 kilowatts into.

I went and looked at some articles about bi-wiring (not bi-amping), too, and it looks as if there may be a tendency for bi-wiring to pass more total current (ie between both sets of wires) at the crossover frequency, and that is surely the last thing one wants since at the crossover frequency there will be the most phase difference caused by the capacitors, no?
