Do you have balanced headphones? If so, which ones? No.
If not, are you looking at balanced headphones or a balanced amp in the future? Most definitely.
For balanced headphone output, how important is it to have dual three-pin XLRs as well as a 4-pin XLR? I would love to see 4-pin XLR become the standard for balanced connection. As far as I'm concerned, 3-pin XLR should go the way of the dodo.
For a balanced amp, how important is it to also have single-ended outputs? What's the point in getting a balanced amp if I'm going to use the single-ended output? Don't really need single-ended.
If single-ended is important, is the quality of the single-ended outputs as important as the balanced outputs, or is this more of a “utility” thing so you can use all kinds of different headphones? I guess if you can put a single-ended output on there without driving up the cost significantly or compromising sound quality on the balanced side, then go for it, but if it would cause you to have to sacrifice sound quality in any way for the balanced outputs, then leave it out.
I'm very excited that you guys are looking into a fully-balanced amp. IMHO, when it's done right, a fully-balanced amp is awesome.
