How many different versions of "The Wire" are there?
 
Just curious how many types OPC designed. I know there is the SE-SE, then the BAL-SE, then the BAL-BAL. I'm suspecting there's a few more like what I see qusp building. What are they?

There are 4 headphone amp designs all in one thread:

The Wire mkI (BAL-SE I think, it was done and dusted before my time)
The Wire SE-SE, BAL-SE, BAL-BAL

And 2 power amplifiers:

LPUHP - Effectively BAL-SE with 6 extra buffer chips for higher current output than the headphone amp, 16W into 8R.

Class AB LME49830 with lateral fets

opc has a few other designs floating around as well but that is The Wire series in a nutshell as far as I know.

Thanks this info is very helpful. I'm curious as to what else he has up his sleeve. I thought I read somewhere that he's putting out a commercial version of "The Wire".

Correct, opc is working on a commercial version of the LPUHP.

indeed he does, there is the NTD1 IV stage, a version of the F5 in mostly SMD and a couple other things, but if I told you i'd have to kill you.
