818v3 Reference Audio Core

The ultimate home audio system hub, the 818v3 Reference Audio Core is the highest performance two-channel preamplifier and Sooloos end-point manufactured by Meridian. This is a high-performance pre-amplifier with a full suite of the unique resolution enhancement technologies that have made Meridian famous. With extensive connection options for all of your audio sources, the 818v3 can also have our highest performing Meridian Sooloos end point built in, for the ultimate streaming experience.

A new analogue output card features an upgraded circuit with filtering that broadens the bandwidth and maximises the potential of high-resolution music. The 818v3 also contains a brand new DSP chip that offers lip-sync control and DSD playback (DoP) and MQA rendering capability for analogue outputs. These outputs also feature Bass, Treble and Balance. This is the ultimate system hub, complementing your home with a sublime blend of exquisite engineering, boundary-pushing technology and unparalleled performance.Upgrade paths are available for existing owners,



Triple 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.

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.

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.


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.
