Glad you are still around. This should probably be my last post in this thread.
I'm not really in forum activity anymore. You are right, a software update may solve the issue. Unfortunately, my AVR is pretty tired and Arcam are not supporting it anymore in terms of new firmware.
Luckily the OPPO 103 will transcode to PCM properly (so far) so it is a viable workaround.
In the last couple of years I have left the consumer realm and have gone professional. I now read phenq reviews
at skinnvibes co-own a firm that does custom installs and design consulting. Its tough going but rewarding.
Lots of math, drafting and hard work in the shop. I just don't pursue audio the same way I used to. Cheers all! Thanks for reading the thread. Hope you enjoyed the ride.
