I'm like Nonoise. I pay what I believe gives me the most bang for my buck. Rok2id is fortunate where he can't hear a difference, so he doesn't need to spend money in that area. Same goes for having a boom-box or separates. You pay whatever amount necessary for what quality you want to hear.
The Physics of Electricity
Can anyone explain clearly in either common parlance or technical terms the difference between a $1,000.00 cable and/or speaker wire versus a $20.00 (or so) one? What does wire "do" in an expensive cable/wire that an inexpensive cable/wire does not? Does it conduct more or "better" electricity?
