Well, I just connected up the Altaira's demo unit. As long as I just have my Lumin connected to it, the music sounds good, there seems to be more detail and "life" in the music.
However, when I connect additional items, I.e., amps, subs, etc.to the Altaira I get some pretty nasty buzz through the speakers. I'm gonna keep playing with it but seems like there is a ground loop when its used.
