New firmware 8.1.3

[MusicFirst]

After my vacation I was happy to see my Devialet 200 back from a warranty repair (burning smell), straight away installed the 8.1.3beta and decided to play it for a week.
Today the first listening session I find it quite musical, the strange mid bass thump has gone and I can play a bit louder (Raidho X1 and JL audio Fathom F110).
But the annoying thing is that the right channel is slightly louder then the left channel, pulling the soundstage to the right for half a meter.

All in all I am getting a bit frustrated with the Devialet experience, I won't be buying the second one to make it a 400. In my first system I am using Accuphase amplification for years, never had any problem, just turn it on and enjoy the music.

I have had a similar experience with my D400s, requiring me to adjust the balance to the left by 24! to center the image. I have also started to experience an intermittent dropout the starts on the RHS speaker and sends a ripple or echo through the left channel. The effect is very fast and the initial dropout is over in about a second. The effect upsets the sound quality for several minutes until the system restabilizes. I'm not certain if its the slave or what, but its very disconcerting especially if one has been drawn into the music.

FWIW, both of these effects started when I switched to 8.1.3. beta from 7.1.3 (I spent little time with other 8. FW., I haven't had time to go back to any of the 7.x.x. FW.)
