I read what he wrote as saying the amp is balanced internally, and he generates a single ended signal to go to the headphone jack. That's why there isn't an rca option. If he was single ended internally, he'd have rca outs as well, at a minimum.
I never actually managed to close the deal, but I came REALLY close to sex with twins once. In hindsight, I'm glad it didn't work out. 1 psycho girl post breakup was probably enough.
If anyone gets banned from headfi for what they say here, then it says more about headfi than here. If anyone has a problem with what's said here, respond here...
