We wire our own cables using Squareplug brand connectors and Mogami cable.
We use Squareplug SP550-S to go into the dot9 in stereo: https://btpa.com/sp550-sbk.html
For the outputs we use Squareplug SP
SP400BK: https://btpa.com/sp400bk.html
If you prefer straight plugs, you can use Squareplug SPS4B, which is what we use to into the H9.

The connectors take Mogami W2314 for mono https://btpa.com/w2314.html
and Mogami W2528 for stereo.
