Take the long view. Your system will not remain static in its needs. A 15' speaker cable will not sound different than a 10' and later you may have need of that 15' length. Plus, who is going to purchase a used pair of 15'/10' speaker cables? Hummmmm?
Newbie Q: speaker cable length? Different OK?
Hi. This is a complete newbie question. I've ordered two 10' amp to speaker cables, but I really need 15' on one side. Monoprice (for better or worse) is willing to RMA the cable(s). Should I go with two 15'? Or is simply swapping out one 10' perfectly acceptable for signal?
