SPARK - only for Phantom speakers?

[Axel]

Spark can only be used with Phantoms. It streams music fine from an iPad, for a while.
OTOH I keep "losing" a Phantom from the setup. The sound stops from one speaker and a look at the setup shows Spark is now only seeing one speaker.
I have to start the setup over again. 3 times out of 4 the setup hangs and I have to reset everything and try again.
I assume this is either the firmware crashing in one of the Phantoms or a Spark bug.

IMO this kit is not actually ready for sale yet.

Sounds like Devialet should be paying you for beta testing, Frank!
