Prime Headphone Amplifier
Personal Space

The Meridian Prime Headphone Amplifier delivers a lifelike performance from any headphone and is designed to appeal to audio enthusiasts who seek the highest possible performance from conventional analogue audio sources.

With three inputs, one dedicated and optimised to USB sources for computer audio, discrete pure analogue inputs on RCA for traditional sources, and a 3.5mm connection for portable devices such as a smart phone, while Analogue Spatial Processing (ASP) offers “outside the head” listening through headphones.

The Prime features Meridian resolution-enhancement technology including low-jitter clocking, upsampling, apodising and full support for MQA.

Key Features

Analogue Spatial Processing (ASP) allows for complete immersion, blending the left and right channels to help you forget that you’re wearing headphones

Digital and analogue inputs - Input either computer audio sources via USB or analogue sources such as your phone, tablet or Hi-Fi 

Meridian’s unique Apodising filter fixes errors in digital recordings, making any music sound more alive, regardless of its source.

Double skinned, bead blasted metal chassis construction echoes that of Meridian’s full size components. This ensures that noise is kept away from critical audio components for lifelike details that are critical for headphone listening.

With its extensive Research and Development programme Meridian has pioneered the development of a host of innovative audio technologies many of which feature in today’s Meridian products.

Filters are critical in digital audio. Commonly they introduce distortion and harshness because of "pre-ringing". Early digital recordings suffer from harshness too, due to primitive filters. After painstaking research, Meridian developed a special filter that avoids pre-ringing, so it can be steeper, cleaning up the effects of early filters. The result: a better, cleaner sound from recordings old and new.


MQA is a technology that captures the full magic of an original studio performance. Using pioneering scientific research into how people hear, MQA delivers master quality audio in a file that’s small enough to stream or download – the days of sacrificing quality for convenience are over.

Uses a complex digital filter to double the rate of samples from the source to improve resolution of the finer details in the record. This means that even with a standard source such as CD using our upsampling technology we are able to significantly enhance the listening experience.
