Using Sonos by Toslink in ?

[streamy]

They have announced that the next version of Spark will support optical input on the Dialog.
So Sonos output to Phantom will work.

But the main issue will probably sound latency, it not very probable that the extra network latency added by the Dialog and its wifi/PLC network will allow it to be in sync with other SONOS speakers.
So It will probably work with just Phantom speakers in a zone...And multiple zones playing in sync will not work...

The ideal solution will be to input the same optical signal in 2 x phantom with an optical splitter (http://www.amazon.co.uk/Ex-Pro-Optical-T...B000RWDUYO), but you'll get 2x mono (stereo mix) on the two phantom .

You'll need to be able to select in some ways if you want stereo mix, left or right channel, I don't know if Spark allow that, if not  you'll have two stereo mix phantoms not real stereo.

No, this will not work and would not improve anything in the current implemenations of the Phantom with Dialog. When you use the optical input of one Phantom the signal content is sent to the Dialog and then distributed to the left and right channels of the Phantoms. There is a delay of about 100 ms. I got an echo of this delay when I used 2 AppleTvs one to the Phantoms and one to another Active speaker (B&W Zeppelin) that normally plays synchronus with the source (MacMini). Normally, my AppleTVs are in sync in a multi-room or multispeaker setup. 100 ms delay can be ok for sync with a movie, but is at limit for 24p movies. 50Hz or 60Hz movies would be better off with 20ms or less delay.
