Why no SPDIF input rather than just analogue and Toslink - I thought SPDIF was recognised as being more jitter free that toslink?

I agree that M comms would be useful, though not sure where I would plug it into as my sockets are already filled up with DSP speakers and a 2nd room system - we really need some kind of M comms hub (like the 511 but for 5C rather than 5M/S cables).
