Some sign of Expert line

Indeed, Expert Pro has a very good sound quality.

However, if you have a configuration with 2 or more units, then the sound quality depends a lot on the interaction between the functionalities you use and the bugs in the configurator / firmware.
I suspect that for those who do not feel the need for a firmware upgrade, this interaction is not applicable.

There is another functionality that is completely missing from Expert Pro: MQA capabilities. This is a "normal" functionality nowadays. From this point of view, Devialet technology is outdated and needs an upgrade.

MQA is a busted flush. It has been on life support for years, loses millions each year with hardly any revenue, and it is only a matter of time before the owners stop putting money into it. The last thing Devialet should get involved in is MQA.
