Meridian Ultra DAC
Setting the standard

Packed full of ground-breaking technologies and world firsts, the Meridian Ultra Digital to Analogue Converter brings our renowned expertise to the analogue realm.

With countless connectivity options and supported formats, including DSD, DXD and MQA, the Meridian Ultra Digital to Analogue Converter boasts an extensive list of user features and performance enhancing innovations. The result is a level of performance that is, quite simply, unachievable with normal DACs.

The Meridian Ultra DAC is the pinnacle of technological audio innovation and, most importantly, designed and engineered to provide you with the most rewarding personal listening experience possible.

Key Features

The Meridian Ultra DAC is the only Meridian product that has a dedicated clock card to ensure the lowest possible jitter. Alongside FIFO buffering, all jitter is folded down below 0.5Hz. As well as reducing jitter, this dedicated high current clock design also reduces low phase noise.

The Ultra DAC is the first Meridian product to feature Dual Mono DAC cards. This provides absolute stability for each of the two DACs so that each one can perform optimally. There is no interference between the two as their power supplies are isolated from one another. This is also complimented by complete isolation on the back end.

The first product to include Hierarchical Converter Technology by MQA.

A Linear Power Supply ensures superb performance on both analogue and digital systems.

Meridian Sooloos, the user-friendly music management platform embodies everything you value about music. Your collection becomes easy to manage, with intuitive simplicity and exceptional speed. It’s designed with a deep understanding of music, and delivers an experience that reflects the unique value your music library holds for you.

Many sources of music are enjoyed through digital audio systems such as radio, USB and Bluetooth audio streaming. To maintain the quality of these musical recordings, they are converted into a common format. Meridian Digital Dither Shaping ensures that digital signal changes are made smooth and seamless, preserving the finest details of the performance. The result is authentic, engaging musical enjoyment, evoking the emotions of the original recording.

As pioneers and leaders in the field of Digital Signal Processing (DSP) technology, Meridian is able to deliver your music authentically to recreate the passion and involvement of your musical moments. Power-efficient, active DSP crossovers are individually tailored to distribute music to each speaker, bringing your music to life.

Traditional audio systems often require large, expensive cables to maintain their performance. Meridian's SpeakerLink uses an “Ethernet style” cable that delivers pristine digital sound and control down a single cable between Meridian components. The result is simple, unobtrusive, and cost-effective cables that are easy to install

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.

Each sample of a digital recording must remain evenly spaced in time. Unfortunately, timing can vary, especially when reading discs. This is “jitter”, degrading music's sense of space and diminishing realism. Meridian's multiple “First In, First Out” buffering system minimises jitter, ensuring perfect timing and improved clarity. You enjoy a clearer feeling of the instruments and their interrelationship.

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. Visit mqa.co.uk for more information.
