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
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.
