You answered your own question while asking it.
It is amplifier with a loudness control.
It is admirable that amplifiers strive to provide a linear frequency response. But that is completely the wrong pursuit. Engineers knew this about 50 years ago when they were designing amplifiers. Since humans listen to them, and human ear has a NON linear way of hearing frequencies, all amplifiers made for humans should all include a loudness control.
THAT is the most important component. It can be adjusted to overcome the shortcomings of a turntable, speaker and what not. You cannot say the same for any other component.
