Depends on how you play the game. A 'nyan!' inserted with surgical precision can bring anyone to their knees.

IIRC, he said they were clunky and he had difficulty wiring it all up. Also, most headphones don't need balanced outputs, and I think Tyll was kinda ambivalent about whether he preferred single-ended or balanced.

That's a headphone, not what you plug headphones into.

Tyll, the guy who basically adopted that connector, said that he regretted using it for his early headroom devices.

No non-headphone devices use the Lemo connector, iirc.

IIRC, only iBasso used the hirose connector for their devices. Most balanced devices from the late 2000s/early 2010s used the RSA connector for balanced.

You forgot 2x 3-pin XLR that Tyll basically adopted during the early 2000s, and the RSA balanced jack that was somewhat "popular" (as far as the head-fi community went) back in the late 2000s. Might be a few more obscure ones that I'm forgetting - Sony's 2x 3.5mm connector, and the 2x 6.3mm connector.

Anyways, I'd also make the 3.5mm connector A-tier, 6.3mm B-tier, and 4-pin C-tier.

I have the black version. You can seriously kill someone with the thing.

Don't some of you solely listen to headphone reviews on Youtube?
