As an owner of the Pioneer PDR-W739, I can say that by utilising the manual digital record level control, the cd copy can have more "volume" or dynamics than the original cd, especially if it is an older cd that has not been remastered. Case in point, I dubbed a copy of Christopher Cross' second cd, "Another Page", which is a very poor recording sonically. The copy sounded much louder and livelier because I increased the level control by 10 dB. On remastered cds, it does not pay to increase the digital level control because the signal will become distorted.
