There isn't?

So it's indeed empty as you said earlier.

Well, guess you learn something new everyday

No, you're talking about very small speaker wires. Sometimes they are shielded, sometimes not. A shield is normally not necessary, but can be used with dual 3-pin connectors if desired. A single 4-pin connector rules out the option.

The main reason that Headroom launched their original balanced amp with a pair of 3-pin connectors is that the original Blockhead was essentially two Maxes strapped together. So, with one Max driving each channel, the headphone output on that amp could only support one channel in balanced mode. A 4-pin connector was simply not an option, with each channel in a different chassis.

It doesn't really. You can wire the shield to the shell on the connector. Most balanced cables the shield is only connected at one end anyway.
