Many amplifiers this feature is mE implemented inadequately and only generates an increase in the depths (possibly + height), which could also achieve the same on the bass and Trebble regulators. This has the disadvantage that when listening to the faint sound Although quite full appears, but soon heard loud bothers the bass appears strongly overemphasized.
At Pioneer, the loudness, however, depends on the position of the Volume slider. That is at low volumes Bass and treble, the volume is increased, this increase will, however, (according to the non-linear sensitivity of the hearing) steadily. In my opinion, this is also very well matched. It is believed this declining control while increasing the volume has not been.
=> With activated loudness with very low volumes you already reached a pleasantly powerful sound, yet not interfere with exaggerated bass at louder listening.
For me, the loudness in this form is a great asset and a great feature of this amplifier.
(A hum of the power supply can be heard on my device only when placing the ear to the case)
