suitable for lower sensitivity and higher impedance
headphones. Low gain’s driving force is relatively small,
suitable for matching with headphones of higher
sensitivity and lower impedance. Super-low gain’s
driving force is smaller still, suitable for in-ear monitors
(IEM) with very high sensitivity and very low impedance.
