New firmware 8.1.3

[MusicFirst]

Now that we have had evidence that it appears that cards above 4GB can give installation errors (without any notices) of firmware updates are we all sure that these differences are in the firmware version or the installation. I have found problems like this myself.

I heard a little rumour that the guys at Devialet find the fact that people hear differences quite amusing

The rumour about amused Devialet people is a good one, maybe more of a fact  

It's like engineers fixing the headrest of a car, and the customers claim that the car is driving better (or worse) and faster than ever.
I am sure Devialet's engineers are simply stunned and laughing about "audiophilia nervosa".

I'd say this rumor is worrying. If the engineers at Devialet can not hear the difference between, for example, 7.1.3 and other versions it is a problem. Then we can not rely on Devialet to create a specific quality in a newer firmware if they wanted to, simply because they can not hear it and hence do not know what created the difference..

Maybe this is why the Sound Quality has meandered from FW release to release.
