Great news – thanks for the update. And I’d be interested to know if the MCL2P ‘power down’ starts working as it should.
The conclusion: everything works perfectly!
I unplugged the whole system to do some work on cable tidying, etc.
When I put everything back together, slowly, over a whole Sunday recently I ended up with everything in harmony: Beovision activates MCL2P on startup and deactivates it at standby/switch off and the sound is superb (as mentioned before – but man it’s so good it’s worth mentioning again).
