Update on the sound of the D-03X.
At first it sounded about the same as my Oppo 103.
Now with it being left on 24/7 and several hours of playing music I am very happy to report it is sounding significantly better than my Stereophile class B rated Oppo 103, thankfully.
Only real complaint is the battery cover for the remote. The remote itself is nice, the cover fits so poorly it falls off. Very surprised.
