MAC Air connection to Phantoms help please.

[f1eng]

Spark doesn't 'see' the mac.

I may be misunderstanding. You should be running Spark on the Mac and it should "see" the Phantom system. "Air" is the software for wirelessly connecting to one of the amps, not to Phantoms.

I have Spark on my iMac, where most of my rips lie, and my laptop, which has very little music on it but is in my lap  With Spark running on both my lappy and iMac I can chose what to play from either/both on my laptop, so I just launch Spark on the iMac then do everything else using Spark on the laptop.

Until yesterday I thought all the problems had been fixed with the latest firmware, but I was back to hesitations and stuttering which led me to unplug the lot and go back to a proper hifi before one CD had been played.
Devialet asked me to connect everything by ethernet as a test but it is so inconvenient to do I haven't got round to it, not least since it was has worked fine several times recently.
