Packed full of ground-breaking technologies and world firsts, the Meridian dedicated 384 kHz/24 bit Meridian Ultra Digital to Analogue Converter brings our renowned expertise and pioneering reputation to the analogue realm.



With myriad 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:

  • Resolution enhancement technologies, including dither shaping and Meridian upsampling and apodizing filters, are employed to deliver the very best performance from any digital source.
  • For the very first time on a Meridian product you can choose between three different upsampling DSP filter options, depending on your personal preference.
  • The Meridian Ultra Digital to Analogue Converter is the first product in the world to feature MQA’s patent-pending Hierarchical Converter Technology, which pushes the unit’s performance far beyond that of any Digital to Analogue Converter currently available on the market.
  • The Meridian Ultra Digital to Analogue Converter features Dual Mono DAC cards to provide absolute stability; a unique feature of its construction.
  • Equipped with our award-winning Sooloos music management and streaming platform for the very best user-friendly experience.

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.

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.

From any room in your home; on portable devices, computers, or even via the web across the world; your Meridian system lets you access, browse and play your library at any time. And you can tune in to internet radio and access popular music streaming services such as TIDAL, simply and easily too.

Master Quality Authenticated (MQA)

Sourced from the original studio master recording as approved by the creative team, MQA combines an advanced new digital sampling technology that captures extremely high frequency timing and detail in an audio signal with an equally novel system to “encapsulate” that data into a form for delivery using any lossless file format or streaming. The listener’s decoder reconstructs the entire original signal, bringing up an indicator confirming that what they are hearing is exactly the same as the original master. Without the decoder, the listener enjoys CD quality reproduction. Its most advanced form, “MQA Studio”, uses the technology in the studio to generate an even higher quality master recording as the source.

Digital Dither Shaping

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.

Digital Signal Processing

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.

Meridian High Resolution (MHR)MHR was the first approved encryption method for transferring high definition digital audio between components. Previously, it had to be in the analogue domain, reducing quality. MHR allows secure movement of high resolution digital audio within a Meridian system, without compromise, improving quality by reducing cyclic repetition.

Meridian Apodising Filter

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.

FIFO Buffering

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.

Dedicated Clock Card

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.

DSP Upsampling Filter Options

The Meridian Ultra DAC is our first product that gives the ability to select between three DSP upsampling filter options when playing back standard resolution audio files. This function relates directly to the material you are playing as opposed to the genre. The options include long, medium or short filters:

Long: A filter with more stages, giving a steeper response. It removes artefacts created by pre-echo or noise in the recording and mastering process, giving a more musical sound where artefacts are present.

Medium: A good compromise between removing artefacts and preserving spatial information.

Short: A filter with fewer stages, giving a shallower response. It provides the best time response, emphasising the spatial cues in well recorded music.

Dual Mono DAC Card Construction

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.
