Too bad. I guess I am the only one who thinks Manic Moose is fine. 
Could you please tell us how you're oplaying music via Manic Moose? Are you using the streamer or via usb thumb drive?
I tried an experiement last week. Seeing as the scratch disk only accepts FAT32 formatted thumb drives, I bought another 32GB USB thumb drive, formatted it as FAT32 and put a load of music onto it and stuck it in the BDA-3.14.
The music files played via this new FAT32 drive play (so far) uninterrupted. I'm really busy so I can't give it a full array of tests. I also played some 32bit/96kHz sound files - no problem.
One side-effect (actually I'm not sure if it's a side-effect or something Bryston have changed on their side) is that Manic Moose no longer lets me change the DAC inputs, which is fine because I have the remote for that. If OS3 jettisons that part of the system in favour of stability, I'm all for it.
Another side-effect I've noticed is that when interacting with MM/myBryston on my cheap Lenovo tablet I keep getting notifications that the signal is dropping out every now and then. This has no effect on playback, only interaction.
I'm not sure if the stability is because of the FAT32 formatting or the virign thumb drive, so I'll keep experiementing with formatting systems and drive sizes until I dial it in (it's kinda fun and the SQ from the streamer is really good + 32GB is hardly enough memory).
On the other hand, my half TB thumb drive which gets written and erased a lot still plays fine on my Universal Dsc Player with zero issues, but resolution is capped at 24bits. But that system isn't online and everything is controlled by a remote, which probably keeps things simpler.
