Description
"Simply put, the SPL Phonitor x is the best “sounding” solid-state headphone amplifier I’ve heard." - Ian Dunmore (@Torq)
Check out Ian Dunmore's(@Torq) review of the SPL Phonitor X here!
The SPL Phonitor X Headphone Amplifier + Preamplifier is the ultimate headphone amplifier. It offers both balanced and unbalanced connections for headphones. With up to 3.7 W output power the Phonitor x delivers an impressive performance. 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. All in all five input sources can be connected. Two of which are analog stereo inputs (XLR und RCA) and three more are digital stereo inputs (USB, coaxial and optical).
