Dunu ripped off the design of a Lemo connector for their modular cable system. (Specifically the Lemo model 0b.304)
You'll find tons of chinese copies of this design on AE. Some of them are quite sleek and small.
EDIT: Yes, the YC8 would work. But you can find better and smaller.
Awesome thank! I'll give those a look.
There is also GX16 a bit more bulky but very cheap. You also can find 2.5mm TRRS male/female I don't think anything is smaller than that.
Definitely a bit bulky for my uses, but good to know what is out there. I've been considering 2.5mm, but think it may be a bit fragile. 4.4 is a good solution, but then the size is close to locking connectors. Major points to each of those though because then you end up with a shorter more portable wire if needed with zero adaptor necessary. I saw Currawong mention in one of his videos that he now uses most cables with 4.4 balanced and uses an adaptor for 1/4 in or xlr depending on the amp.
