It doesn't matter as much as many would have you believe. If you replace
the speakers it's definitely worth getting something *slightly* better than
bell-wire but don't go near anything remotely esoteric! If you pay 99p a
metre for cable from Richer Snouds you'll get something that'll be *more*
than good enough and will never need upgrading.
