I believe the Phantom I Custom is an ordinary Phantom sold with a 5 year warranty through the "professional" channel. The Phantom II Custom has Dante built-in. For the Phantom I Custom you'll need a "Dante dongle" which is ethernet in & optical out. Devialet says that Phantom I Custom is Dante enabled, but the "Dante dongle" is not in the box AFAIK. It must be purchased separately . Wireless gets disabled when "Direct optical" is enabled.
