Seeing very few reviews, mixed at that. This unit uses AKM DAC, so this piques my interest. Has anyone tried it? TiA! 
I've been using one for a while - but am not using the analog outs. I made a post about my experiences with it here
http://db.audioasylum.com/cgi/m.mpl?forum=pcaudio&n=28294. I've been happy with the sound in general. And Jriver media center did fix the problems I listed in that post.
With my laptop, I see about 45 percent CPU usage when music is playing. If I try to do things such as surfing the web on that computer while music is playing, I get glitches in the sound.
Overall I'm pretty happy, but I may yet have my SB2 repaired and go back to that.
