I'm getting ready to build a custom DIY cable for my HD600's and was wondering what the purpose of the XLR-1/4 combo output was on my Corda HA1 MKII. Is this a "pseudo balanced" output as described on Van Den Hul's page in Fig. 2? Is the output equipped with a cross coupled output stage or an output transformer?

I'm also wondering if this XLR output is worth incorporating into the design of my cable. Anyone have any experience with this?

Whoops. nevermind

I think those jacks were chosen simply because Jan Meier liked them. I don't think the XLR part of the jack is even used.

That's what I was wondering. Maybe I should just email him and ask. Just thought I'd try and get some input from fellow Head-Fier's before I bother him with a potentially stupid question.

did you get an answer from Jan? I was going to ask him myself when I found this thread...

Nope. This amp is entirely single-ended. Output is just a BUF634.

The XLR portion of the headphone connector jack isn't used.

Here's the answer I got directly from Jan-
"This output is not connected. These combined sockets are normally used for professional equipment. They're used since they're of high quality and easy to assemble (PCB-mounting) but the XLR-option is of no value
for this application."
I'm glad someone else was wondering the same thing. I had a feeling that the XLR portion was not functional, but wanted to make sure.
