Linn Majik owners....

Majik is designed to work with 4 ohm loads, so no problems there. I used just regular banana plugs, don't know how z-plugs look like? Btw great choice.

Z plugs should work.

Yes, like Eldragon said. Majik will just about double up the watts output at 4 ohms. The connectors are BFA, designed for European Union safety standards. Linn and Arcam (& other British brands) dealers should have them. But rolled banana plugs (like Z plugs) seem to fit.
