I’m trying to find the source on this, but someone compared Monster Cable speaker wire to audio run through coat hanger wire and, in a blind listening test, found no noticeable difference. The jury is out on this topic — and gets very enraged when you talk about it — but let’s just say I’m leaning towards the “wire is wire” camp unless you’re dealing with supercolliders.
UPDATE – Here’s the thread.
