Just enough inputs for me. (Assuming they still have two optical digital connections.)
One digital for AirPlay (ATV3 or AEX)
The other one for the digital optical (audio) output from the telly. (Takes care of Blu-ray and Humax too.)
And one analogue connection for an FM tuner.
However, that would mean three more interconnects (1 x L & R RCA phonos + an extra optical) and three more mains cables (ATV3/AEX + FM tuner + extra one because both speakers require mains leads).
An FM tuner and an ATV3 would also take up as much space between them as my 'all-in-one'.
So, purely in terms of de-cluttering, ADM9s (despite having their own DAC and pre-amp) would be a retrograde step.
And I would not give up on FM (until it's actually switched off) because... (a) the internet - despite a very reliable and fast cable connection - is not as consistent as FM broadcasts and ... (b) I like it and still use it - almost daily - despite using iPlayer Radio and AirPlay more. Don't care if it's not 'hip' or modern or whatever. It sounds great and is a useful backup if the internet is sh###ed (or iPlayer is down for some reason). Those occasions are rare but can (and do) happen.
I would also have to rip all the wife's CDs to her own iTunes and sync them to her own iPod Touch (she hates smartphones) because she regularly plays her CDs on the system and prefers that to any kind of streaming. So thats another £199 (cheapest new 16GB iPod Touch) on top of the cost of an ATV3 for AirPlay (£99) and a good tuner. (And absolutely no thanks from the wife.)
That's a lot of faffage (and cost and time and clutter) too far, before I even contemplate the £1400 for ADM9s. (Yes, yes I know they 'only cost £700' on ebay BigH but that goes for everything else too. It;'s a given that used hi-fi - whatever it is - costs less than when new.)
This goes for any active speakers (even more so because 'traditional' actives don't usually have DAC and pre-amps built in) but we are discussing ADM9s.
