I have some unused K400 spare and I'm thinking of creating 2x 2.5m pairs of K200. These would then have black mesh sleeving applied to make it all tidy as the cut edges are not very attractive (something like this: https://uk.rs-online.com/web/p/products ... lsrc=aw.ds)
Connectors would be gold plated z-plugs which fit 4mm banana sockets or BFA pins (such as used on the AV5125 amps), fitted using traditional solder.
All neatly finished with heat-shrink.

Is there a demand out there for such cables?
