Firmware 12.3.0 + DOS 2.2.2

[Confused]

I've always thought about it and never dared to ask, if Devialet has its D / A converter based on Analogue Converter chips, D / A T.I. PCM1792, how is it that people notice sound changes with every software update, .. I would understand this with DAC chips based on FPGA, but not on the Devialet, thanks for clarifying it ...

And not wishing to be rude to anyone (myself included), but just because people hear a difference doesn’t necessarily mean there is one.  

I didn't want to say it 

This could be another question for Mathieu Pernot at the July OAC event.  Are there any technical reasons why the beta and latest versions of the firmware can influence sound quality?  Have any changes to the beta and latest versions of the firmware been specifically intended to improve sound quality performance?

For the record, I am as sure as I can be that something happened at the beta 12 / 14 stage, but feel free to have a good laugh at me if Mathieu clearly states that this is impossible.  It is a tricky area though, many of us think our system sounds different one day to the next with nothing changed, so how can you accurately deduce sound quality changes from a firmware update?  Either way, I would love to know what is done in these firmware updates and if there is a technical reason for SQ change.  Facts are good!
