When Bluray playback there is nothing to complain about: Great image and sound convincing. However, the disaster takes its course, once you get playing a SACD: The sound from the HDMI Main output is on the rear right surround channel apparently a false signal (it could be the LFO), at least you can hear there usually only a muffled and faint growl , If you try to redirect the sound output via the second HDMI, you have stereo sound (and only this, a SACD multichannel output via HDMI 2 did not succeed, do not care if I spend the signal as a bitstream and edit the LX85 let or PCM Output Select). For SACD Wiedrgabe this beta version is therefore utterly unsuitable. Although these errors do not seem at all LX55 occur (in the relevant forums there are quite even users without problems), but you just know not what you get. In my going back definitely.
Update: After the current upgrade is now works the SACD playback. Thus, there is nothing to complain, I'm satisfied. That took to the Troubleshooting however almost half a year (player already appeared last year), is not necessarily ideal.
