Reading this thread makes me think that it worth a quick reminder that the "second unfold" for MQA does not actually provide any additional data from the music file, or indeed anything of use for a Devialet Phantom. The second unfold is upsampling (which a Phantom does anyway for inputs below 24/192) and the imposition of a minimum phase filter.
The first unfold does matter, and this can be done in some music playing software, such as Roon, Tidal and others.
I wrote about this last year in a post regarding MQA for the Expert range, but in principle it applies equally for the Phantom.

The simple answer is to make sure that you have software that will perform the first unfold, and then don't worry about the second unfold, it cannot benefit a Phantom. In fact arguably the second unfold is of little use even to an MQA DAC, other than being able to offer a nice looking file bitrate on the DAC's display and a blue light. The actual file bitrate shown for the second unfold is bogus, it would be no different to a Phantom displaying 24/192 when playing a 16/44.1 file, just because the Phantom has upsampled the input.
