Meridian Prime Headphone Amplifier / Power Supply - Silver

Reference Quality for Headphones
Meridian’s Prime Headphone Amplifier is a reference-quality analogue headphone amplifier that can replay audio from both analogue and USB-based sources.
Built into an elegant and compact Allen Boothroyd-designed metal case, Meridian’s Prime Headphone Amplifier also provides a preamp output to drive an external audio system or analogue active loudspeakers and fully supports Meridian’s revolutionary MQA technology for studio-quality replay.
The Prime Headphone Amplifier is designed to appeal to audio enthusiasts who seek the highest possible performance from conventional analogue audio sources including personal stereo players, or from a computer via USB, listening on headphones, a conventional audio system or analogue active loudspeakers.
The Meridian Prime Headphone Amplifier can be powered by the wall-mounted supply provided or, for even higher audio quality, by the Meridian Prime Power Supply. The use of this external power supply means that AC noise is kept well away from the pure analogue stages of the Headphone Amplifier.
