Cable lengths


I am a novice, yet must ask the question to budget my future upgrades if possible. I need 15ft speaker cable lengths to one electrostatic speaker and the other only a few feet. Can
I use differant length cables without damaging the sound quality.

Since the signal travels at the speed of light, there shouldn't be a timing difference but it's still a good idea to keep the lengths the same.
Great response and thank you for the knowledge. While we are on this topic what cables would compliment electrostatic speakers. Clueless and some of you have pointed out electrostatic speakers may require special considerations.
Actually the propagation speed for the average cable is probably about two-thirds the speed of light.

Velocity (m/s) = Sqare root (1 / (Li*Ci)). Li = linear inductance of cable (H/m) and Ci = linear capacitance of cable (F/m).
There are no absolutely newtral cables. The active resistance plays the smallest role especially in the wires of 10AWG or thicker. The reactance will play more important role(especially inductance). If your amp is high current and can take high capacity loads than you will not experience any audiable differences.
