Correctly implemented, there isn't background silence with digital, just low level noise. With 16 bits one will be listening to dither noise which is at -96 dB below peak levels. This will be audible in a quiet room on audiophile quality recordings that include the full dynamic range of a large symphony orchestra assuming there is sufficient amplifier and speaker headroom to reproduce row five concert volumes and the neighbors allow this. (Often one will be listening to microphone preamplifier noise which may be at a louder level on distantly miked recordings.) If one listens to a live analog microphone feed one will also hear noise. Indeed, human hearing is just about sensitive enough to hear the thermal motion of air molecules hitting one's eardrums. If there is "black" silence in a digital recording it indicates something is wrong with the recording. One should be able to hear noise when putting an ear up close to a tweeter.
Extra noise may be perceived as "good" if it masks low level distortion due to a poor quality recording or playback. However, any noise that is louder than the hall noise in the recording venue is going to detract from the quality of reproduction. If the noise is in the playback system it will make it impossible to hear all the information on a recording.
(These comments do not apply to pop or rock recordings or other non-acoustic musical genres which have been deliberately mutilated by the engineers for "loudness". One should definitely not attempt to optimize one's system to make these recordings sound "good". These recordings may indeed sound "black", especially after one has destroyed one's hearing.)
