Reply to comment by NaZul15 in Question: what headphones can take balanced output? by NaZul15

Certain devices may favor one output over the other, it doesn't make the "balanced" headphone output universally "better". Let me use the Cayin iHA-6 and your Sony as an example... via the trs (SE) output they would see a 10 ohm output impedance to a 16 ohm nominal headphone, this is an impedance matching issue. Assuming the Sonys are like most dynamic headphones there will be a rise in impedance near the reasonance frequency of the driver... in the bass region... that gets boosted when fed a high output impedance.

Via either the dual 3 pin XLR or 4 pin XLR that same Cayin has a .3 ohm output impedance which would NOT result in any measurable FR changes. Headphones below 80 ohms are best ran via these "balanced outputs", above that threshold there are minimal differences between the two on that device.

Interesting. Does that mean higher impedance headphones don't have this problem as much?

I was in the process of a quick edit, see above now.

Good to know, thank you. I knew it wasn't placebo, but i'm not surprised by these skeptical audiophiles, bc there's a lot of snake oil in this community.

That particular amp allows you to take impedance matching a bit further... one of the TRS jacks is 120 ohm output impedance, only really useful with HD800, T1 Gen 1, etc... but can be fun to experiment with.
