Hyperstream
The SA45 achieves exceptional sound quality through a new 6-layer digital audio and streaming platform. This design includes a ground plane that eliminates noise and interference, protecting sensitive audio components. The system also features ESS’s latest Hyperstream iV DAC in a balanced configuration, with advanced jitter elimination for pristine sound. The linear toroidal power supply further reduces noise, ensuring efficient performance, while a standby switching supply operates for peak efficiency.
Rich Class G Power
Drawing on decades of innovation, the SA45’s 5th generation Class G amplifier design delivers superior sound quality and dynamics. This amplifier is renowned for being more efficient than traditional Class amplifiers, with components and materials meticulously selected for uncompromised audio performance. This ensures that the SA45 produces dynamic and rich sound, perfect for any audiophile.
Beautiful Screen
The SA45 is equipped with a large 8.8″ high-resolution display, making it easy to view album artwork and metadata.
Your Music, Your Way
It supports a wide range of devices and streaming services, including Apple Airplay, Google Chromecast, Spotify Connect, Tidal Connect, and Roon.

KEF LS50 META Speakers
The Kef LS50 Meta is the replacement for the iconic LS50 speaker which was released way back in 2012 as a limited anniversary model and was one of the most award-winning speaker products ever released by KEF, receiving accolades from such publications as Stereophile, What Hi-Fi, and The Absolute Sound. So the new LS50 Meta have a lot to live up to.
Pushing the Technological Boundaries
The new KEF LS50 Meta pushes the technological boundaries in its mission to create the best possible sound, Metamaterial Absorption Technology (MAT) is a highly complex maze-like structure that eliminates unwanted sound from the rear of driver, resulting in a purer, more natural performance. MAT is the physical manifestation of that drive. The result of a joint development project with the Acoustic Metamaterials Group, MAT breaks completely new ground in loudspeaker design….
LS50 Meta’s baffle is engineered from an injection-moulded Dough Moulding Compound, while inside the cabinet cross bracing and Constrained Layer Damping combine to deaden internal vibrations. The result of such meticulous attention to detail is the lowest coloration of any speaker in its class. Using Computational Fluid Dynamics, the port flare and profile of LS50 Meta’s patented off-set port is calculated to delay the onset of turbulence, and the flexible port walls prevent resonances from colouring the midrange. This leads to improved clarity, with exceptional depth and detail..
Redesigned and Improved
KEF's trademark Uni-Q driver has also been redesigned and improved, incorporating the new Meta technology. The Kef LS50 Meta certainly shares a likeness with the original. But while LS50 is a great speaker, LS50 Meta and the technological advances it boasts offer a truly dramatic improvement in sound quality…
The Kef S2 Floor Stands are optional but a must in our opinion, improving the performance and making them look simply stunning in any room.
