cable length

I agree with Elizabeth, get the very best you can afford. I would also suggest keep the speaker cables as short as you can get by with. Power cords, again they are by the foot cost, so that must be concidered. If you agree with that power cords can improve your system, than the longest you can afford to maximize the benifit.

Jadem6 is right. Shortest possible speaker cables and longest possible power cables (but there is a point of dimmenshing returns beyond about 6 feet).

Just a question on the same topic. I wonder if it is harder to sell cables under 8 feet? This might be a factor when considering purchases.
