Transmute your Phantom into Gold Phantom!

[EvPa]

As per what was written on Devialet's website (at least in French, I did not look at the English version before they changed it), they were indeed originally supposed to send the new Golds first and you would have sent your Whites or Silvers to France after getting your brand-new Golds.

They now also offer the option of an exchange at a Devialet retailer though.
