Hmm I am actually not 100% sure, for mine I leave my bitdepth at 24 bits, because that is my hardware native bits. Oh, I just checked the place that you checked, and it seems that mine is outputtting as 32 bits too.
Oh well, I don't really care since it's ASIO and it's lossless playback anyway. Here is some info on the bitdepth on Jriver: http://wiki.jriver.com/index.php/Audio_Bitdepth
Seems like it uses the highest bitdepth that the hardware can support. On ASIO, the output bitdepth selection is ignored in your screenshot. So technically, it's meaningless for me to put it at 24 bits too, since it's ignored.
Thanks for all and for the CTRL tip, very handy. It sounds good to me, enough to buy it? well lets wait and see....
Oh, and the Theater view is cool, esp, on my plasma.
