Some electrostatic speakers have an impedance curve that falls to about 1 ohm at high frequencies. The Soundlabs, for example. And at low frequencies the impedance of the Soundlabs is much higher. So some people use very large gauge wire on these speakers, or position the amps right next to the speakers. (The latter being the best solution.) However, 14 feet of 10 gauge stranded copper has a DC resistance of less than .05 ohm, and I'd bet you won't hear any degradation.
