I am glad to hear that it works well with the EDM:-)
Does on-the-fly software up-sampling (by j.river media center) of 16/44 PCM material to 24/88,1 PCM would do the trick?
Yggy will probably be twice the price of Octave in Europe, so I will probably stick with Octave, at least for some time:)
Dunno for Jriver. I'm using linux based OS.
