I'm looking at what could be a good deal on some 4061s that are hardwired to Sennheiser TRS, and I'd like to redo them in Senn/AudioLtd/Wisy/Lectro SSM-compatible 3-pin Lemo. From what I've researched a bit, one would need the right connector to get the right cable diameter for the strain relief to work properly. Any clues on the right connector and a European source?
