wow wait a second here...
Are we talking about a headphone amp here or a power amp?
It's my understanding that very few headphone drivers are balanced. I thought for the most part it was simply a 4 conductor cable to eliminate common ground for crosstalk etc at the cable segment. Or even worse it's simply bi-wiring BS.
I can understand a headphone amp with balanced +4 dBu inputs but balanced outputs to the drivers?
I believe even the LCD-2 doesn't have balanced inputs into the driver. I think that's called "balanced drive" right?
Sorry for my headphone ignorance guys!
You are right, in fact headphone balancing is seen as a marketing gimmick by many; for those, technical justifications supporting it seem "meh".
To me... It depends from the circuit. For instance there are few some current-output amps that seem to be FTW, and that cannot work unbalancedly.
Jason stated that "it won't be just another amp sending an inverted signal"... So I'm very curious and waiting.
