The 818v3 Reference Audio Core is the highest performance two-channel pre-amplifier and streaming end-point manufactured by Meridian. This is a high-performance pre-amplifier with a full suite of unique resolution enhancement technologies that have made Meridian famous. It includes extensive connection options for all your audio sources and also has the highest performing Meridian streaming end-point built in which is Roon ready. The latest edition offers significant improvements including the decoding and rendering of MQA sources to deliver studio quality reproduction via both digital and analogue outputs.

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.

Meridian’s 818v3 ensures the lowest possible jitter by incorporating an advanced clocking regime and three Meridian FIFO buffers to ensure the purest playback achievable.

Finished in high grade materials, the 818v3 features sculptured end panels and is available in black or any of the complete range of Meridian Select colours.
