Sommer Cable SC Isopod SO-F22 D GY

These cables, with foil-shielding, have memory effect, and are great both for in-rack wiring between components where it will stay put, and wiring inside-components for DIY projects.

No good for high impedance signals (goes without saying), or for uses that require continual winding and unwinding, but for its intended purposes, probably the best thing out there.

For those uses in which you need flexibility (continual winding and unwinding), however, I would recommend the Sommer Cable Cicada SO-D14.

I am using this cable as it is thin and doesn't take too much space. It has a slight memory effect but all in all it is good as microphone cable, as patch cables. It is a fit for all. I do not know if for high impedances if it will do the job ok.
