Thanks Joshti. Will do. I also plan to check out some of the USB/SPDIF conversion cables. In the meantime, I'm doing some research on these 5 filter settings, and rediscovering my extensive CD collection, which has been gathering dust since I was bitten by the vinyl bug a few years back.
Interesting that filter #5, the minimum phase apodising filter (for CD playback) seems to be the same type of filter used by the famous Meridian CD player. For more plain english info. see http://hifiduino.blogspot.com/2009/05/wm8741-digital-filters.html (Filter #4 in that paper is actually filter #5 in the Rega DAC).
