fatboyslimfast:Not really - even something cheap like the Gale 400 strand from Richer Sounds will be more designed with audio in mind, higher current, lower voltage, than mains flex. Normal audio voltages are less than about 50v, whereas the mains cables he has are designed for either 240 or 415v. If you do want to get cable from him, what you need is a multi-stranded (i.e. not single-core) cable capable of carrying at least 15A current - more if at all possible.
This just doesn't make sense current is current what ever the suppy voltage.
Mains flex carries mains with a massive tolerance, have you seen the thickness of a 13amp fuse ..talk sense man, the problem with forums is people spout nonsense as fact and others believe it.
Yes cables differ in capacitance / inductance per meter, but the frequency is relatively low.
You do not 'need' multi core. In fact solid is likely to be of lower capacitance and lower resistance.
It is a low frequency transmission line, from which lots a money is made. I will admit to hearing a difference between solid and stranded cables.
In one of my previous posts, I recommended stranded cable against solid core, simply because I felt that every time I have tried both, stranded always sounded better. I don't know fatboyslimfast's reasons for recommending stranded cable however.
Capacitance is not only determined by whether the cable is multistrand or solid core - it's also down to insulation type, promixity of cores within the PVC shroud etc.
As for current... some amplifiers are capable of supplying steady currents of 12 - 15A into an 8 ohm load (and can go higher as impedance reduces) so peak currents can be as much 30A (and more) - of course this kind of current would only generally be delivered at high volumes - but the capability exists so you have to make allowances for it.
I personally, have managed to cause standard 1.5mm twin flex (2A AC rated) to warm up to the point where the PVC insulation has softened by playing music at a constant 20 - 30W or so (at a party).
It's safe to say that peaks in music do cause quite a demand on current delivery - which is why power supplies are so important in power amplifiers.. and hence cable capacity too....
Of course your last statement:
"It is a low frequency transmission line, from which lots a money is

cables"
Is quite correct - however, money is made by virtue of the fact that different cables *do* give different tonal qualities (I don't believe that it makes a difference to the imaging etc. though - despite claims to the contrary). I am very sceptical when I read quotes like "I now have a holographic sound stage" and "everything is now in 3d" - because this suggests that cables are introducing phase changes to the sound somehow - at differing frequencies too - which is probably an undesirable effect.
