Upgrading to Phantom Gold?

[stadidas]

I upgraded from silvers to golds last week after auditioning them side by side in a Devialet store. The treble extension is much much better on the golds, and the mids are clearer too. Bass is about the same. Having listened to the white phantom when I originally bought my silvers, I can say that the difference is pretty profound between the whites and the golds.
