Schiit Audio Magni 3+ is a fully discrete, current-feedback headphone amplifier that’s extremely quiet and powerful enough for your headphones.Schiit Audio designed the Magni 3+ to work as both a discrete headphone amplifier, and a single-source pre-amplifier. In its secondary role, the Magni 3+ can be connected to an external power amplifier, or a pair of active loudspeakers; a relay mute is part of the design for a delayed start-up and fast shut-down. It’s perfectly safe to leave your headphones plugged in even when you are not using them, and the amp automatically disconnects the pre-out when you plug in a pair of headphones.Legendary Sound.Audiophile Quality.I ship Fast.
