Balanced Interconnects??


Hello, What exactly are balanced vs unbalanced interconnects? I'm looking at some of Audioquests new line of interconnects, particularly the coral, to use as an interconnect between my Rotel integrated amp and CD player. Some of their cables are double balanced and others like the coral are triple balanced.Should these cables be used for special applications or equipment? Any info you guys could provide would be greatly appreciated.

Your balanced cable description is correct, Rockvirgo; however, your description of single-ended cables is wrong. Just before a balanced output the entire waveform is physically split into two voltages, opposite in polarity and equal in magnitude with respect to ground. A single-ended output simply sends the entire waveform through one conductor and a ground. You don't need to carry each half on a separate conductor unless you want to benefit from "common mode rejection", afforded by balanced transfer of the signal.
Yeah I agree electrical energy travels in waves, and either the positive or negative polarity represents the whole waveform. My guess is that single ended stuff has to create the opposite polarity voltage through inversion because it's simply not present at the RCA input.
The AQ Coral sounds great! I'm using it to limp along with my Rotel CD for now. MUCH more transparent and resolving than similar Monster, for example. It replaces the Ruby, and sounds better than it or Topaz, INHO.
