When listening to Susvaras, what position is the volume control on?xlr out of the holo and xlr hp cable: Susvaras at +12 and utopias at -6 (usually).
Although I do not have a Niimbus, I use a Violectric 590 as an amplifier with Holo May (connection via RCA). When listening, I set the gain to no more than +6. In this case, the position of the knob is at the level of 3-5 o'clock and the system plays more emotionally and expressively. Increasing the gain slightly reduces the emotionality and slightly increases the background noise.
