Volume 2 is an active DAW monitoring controller and a puristic high-end preamplifier.
The monitoring volume is controlled analogously with an Alps-RK 27 potentiometer. If the volume is controlled digitally, for example in the DA-converter, the bit resolution decreases with decreasing volume with one bit per -6dB. Usually we listen with about -30 dB at full volume, which decreases the bit resolution by 5 dB.
It is claimed that passive circuits are less signal influencing and more puristic and therefore better. Well, that is not so.
A passive control element such as a potentiometer in the signal path, which is not electronically buffered, influences the frequency response and phase position. Both change continuously as you change the volume.
