Phantom Premier vs Phantom I

[djredeye]

The last four digits form N48 is 4U11

Great, thanks!  And the model number?  (at least on mine it is printed on the bottom of the speaker)

MAX207 / N26N / last 4 digits 4U11. 

My Phantom Gold OdP runs cool (much cooler compared to my Bryston amp and Sim Audio integrated). 

I wrote Devialet re: the chip but got a non-answer "We are not able to verify what chip your particular unit has by the SN". 

Devialet did confirm the unit was manufactured in 2020 and that "Devialet introduced the Phantom 1 and II Matte version in February 2021".
