Bigger = better

But seriously it depends on the amp / cable, the one I use is secure in there, I need to pull kinda hard to take it out and the ones I use for my preamps have a locking thing on both ends.

If I accidentally pull my headphones with 6.3 the 6.3 will come out, with xlr the amp comes flying with the headphones. Which is probably not something you want but it is definitely not disconnecting by accident.

I've never experienced it either and I use 2.5 on the go with a btr5

XLR is S tier cuz it feels cool to plug one in

I don't think gaming differs much from music, it's just preference.

Unless the headphone in question has awful imaging it'll work.

I use my lcd-2 (planar), Focal celestee (Dynamic) and Blessing 2 Dusk (iem dynamic + balanced armature) for gaming and comparing any of them I feel no extra advantage between any of them. If anything I'd say iems have the best accuracy when it comes to imaging compared to most headphones I've tried, but I don't think it matters at all, even at high skill lvl.

However wider soundstage tend to feel more immersive which is nice.

Yup, that's what I meant by you also get that on cheaper amps.

The only things I've had bad experiences with when it comes to noise floor is Pc audio and certain audio interface. For example the Focusrite on sensitive iems is pretty bad.

The low noise floor is noticable as well, but to be fair you also get that on cheaper amps.

True, how the fuck am I supposed to afford, headphones, custom keyboards, fountain pens and have money left over for drugs.

The system truly failed us smh

Ranked on how much they affect the sound:

Headphones > Drugs > Amps > Lights > Dacs
