SPL Audio Phonitor x

The Phonitor x is the ultimate headphone amplifier. Thanks to VOLTAiR technology it powers headphones operated both balanced and unbalanced playfully with up to 3.7 W.

The revolutionary Phonitor Matrix delivers the most realistic playback on headphones. As almost all music was mixed for speaker playback the Phonitor Matrix lets you experience music on headphones as being played back through speakers.

The Phonitor x is not just a headphone amplifier, but also an excellent preamplifier that can also drive power amplifiers or active monitors.
