Devialet Silver Phantom

Anybody heard these for an extended period of time? Impressions?
The reason I started this thread was because I heard a pair and was pretty dang impressed but didn't spend a whole lot of time with them. I'm wondering how refined they are and how deep you can hear into the mix.

First impressions were really good. I'll be going back for a longer listening period and report back but in the meantime, if anyone else has heard the SILVER Phantoms, chime in with your thoughts as well!

I heard their integrated amp and thought it was sterile and downright awful.
