I haven't owned an M80 so can't comment on the foibles of it but we are thinking about getting some sounds in the kitchen, so as loyal Meridian owners an M80 / C12 would naturally be high on the list.

Video? Forget it.

Sooloos compatibility? It ranks very highly on here but I'm sure it would be far less important away from HH / Meridian owners although general NAS style ability would be great. Likewise subwoofer out. Likewise the ability to be run in a 3.0 / 3.1 Meridian system. I would guess that facility would be used by < 1% of potential buyers.

Internet radio? Yes please.
Integrated iPod dock? Yes please.
Airplay? Ideally.

I think the F/ M80 did for Meridian what the Evoque is doing for Range Rover; attract a new audience. I understand that 80% of Evoque buyers have never owned a Land Rover car before & 80% of customers are new to SUVs. If that is the target market then Sooloos / sub-out etc will be low on Meridian's list, but if they can be added easily / cheaply then they'd be wise to do so, particularly Sooloos / NAS potential.
