I have found that streaming music such as Pandora sounds better when I use a Mac mini as the source into the BD-105 USB rather than the built-in BD-105 services.
Perhaps this is because the streaming services often send higher bit-rates to computers rather than "devices".
PC/Mac Pandora is of the highest quality (at 192Kbits/s) if you subscribe to Pandora One. Oppo and other media players receive the lower quality streams and no option for them to stream the higher quality stream.
