Value of a preamp?


Other than impedance matching and volume control?

It can offer so many benefits if you have the right one. Soundstage, clarity, dynamic contrast, slam & dynamics, imaging, details, separation of instruments & vocals, etc. 

Can greatly enhance the overall sonic characteristics of a system. Tonality, dynamics, soundstage, and so much more, when it is the right fit with everything else.

It can't add anything but can color the sound in a manner that some find positive.

It is still a short thread, but I would agree to some degree with the preceding statements. Insightful and helpful. In my case, achieving synergy between the ear, room and gear is with a good preamp/amp combo. No right or wrong. 

@OP - Well, impedance matching and volume control are two fairly critical functions. For the preamp naysayers, the reality is that any source component that can drive a power amp effectively has a preamp in it. So it depends on how good a preamp you want.
