New dos2 stereo deferent firmwares

[Walzu]

Same problem here.. I have updated my speakers at the same time to DOS2, but still one speakers is on 2.8.1 and the other on 2.8.3.

Tried to update, but system is up to date according to devialet app

Are they from different vintages (are the first four characters in the serial numbers different)?  If so that might be the explanation, different hardware versions require different firmware versions..

I bought them the same day, but the serial number range is different indeed. Bit strange to have two different hardware versions then.. one was on stock and the order one was ordered, so that can explain it. Still I hope this will not affect sound in any way
