I replaced the 5532DD in Headphone amplifier xDuoo XD05 Basic with a Burson V5i dual. The sound has changed for the better. The stage is slightly wider and slightly higher frequencies. I checked by digitizing the phone amplifier output with different OPA and then comparing the digitization results with a blind test (abc utility in Foobar player).
