I bought my first speaker cables for almost 20 years recently, when trying out the Martin Logan ELS. My old Transparent Musicwave bi-wire set (that I'd bought with the Krell amp as part of the recommended system) were so heavy on the weedy terminals I thought they'd snap off, and as they were single wired inputs I had to use banana plugs to piggy back them together.
Anyway, I bought a 2.5 metre pair of Van Damme OFC 4mm terminated with decent bananas from 'Lucasoundvision' on eBay. About £50 posted. I cannot fault them in any way. Flexible, neat looking, excellent plugs, nicely packaged, and four reusable cable ties included. Sound absolutely fine. These are the shotgun ones with transparent insulators, not the very similar spec 'blue studio' version that is heavier and fractionally lower resistance (relevant only for very long runs). Strongly recommended!
