Phantoms and home cinema

[road rebel]

I did a quick measurement of audio delay on Phantom using ethernet cable between Dialog and Phantom both running 1.1.2.0
Phantom alone (without Dialog), fed on optical input gives 222 ms delay
Phantom + Dialog fed on Phantom's optical input gives 222 ms delay
Phantom + Dialog fed on Dialog's optical input gives 235 ms delay

This means roughly 5.5 video frames delay. This is way too much to achieve acceptable audio/video sync. The sync problem is obvious and annoying both on dialog lipsync in movies and live music performances.
In pro applications we consider 1 frame delay to be an acceptable maximum since most people can already see a 2 frames sync issues.

I wonder if Devialet can really reduce the current delay to an acceptable value ...

And what about one phantom in mono connected directly through optical without any stereo or multi-room sync?!
