Well... with much curiosity I've swapped my DACMagic with Apogee Duet!
The sound quality I will say that they are about the same unless Duet require a bit of a 'burn in' time?
But there is a convenient of the volume control with the duet.
HOWEVER, I'm connecting my Beolab3 to apogee duet via 1/4 inch converter to RCA converter as provided. When everything is on but no music is playing. I can hear a light humming background noise from the speakers (in fact it is still there during the music is being played but it is just less noticeable. This happen even when I turn duet volume all the way down. It will only go away if I muted duet unit.
The hum sound wasn't there when I were using the DACMagic which make me think that maybe DACMagic produce a clearer sound after all??
Is there something wrong with my setup?
