Key Features

Multiple analogue and digital inputs enable connection to any source within a system. 

Unique Meridian High Resolution up-sampling offers the best possible performance from all of your sources.

A reference Sooloos zone delivers pristine lossless audio quality for all your music.

Re-clocking of the digital audio signal removes timing errors for superior clarity and resolution.

Meridian Sooloos ALL MUSIC. ALL THE TIME.

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.

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.

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.

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.

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


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.

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.

A patented Meridian audio format that combines high bandwidth, security and low jitter. MHR gets the highest possible sound quality in playback systems that use Meridian and enables the encoded transmission of PCM, MQA and DSD.
