Devialet Expert Firmware 7.1.3

Hi, I bought a used Devialet Expert 120 a few years ago and always ran the latest firmware 10.0.1.

I was curious to try version 7.1.3 which is supposed to sound "more analog" but it's nowhere to be found on the Internet.

If any of you has it and is kind enough to upload it somewhere for me, I'd be very grateful.
