Hyperstream
At the heart of the SA35 is a 6-layer digital audio platform that minimises noise and interference through a ground plane across the entire board. This platform includes the latest Hyperstream iV DAC from ESS, providing balanced audio with advanced jitter reduction. A new linear toroidal transformer further improves sound quality, while a switching power supply ensures efficiency in standby mode, contributing to the system’s lower overall noise levels.
Class G
Arcam’s renowned Class G amplifier design is further refined in the SA35. This fifth-generation Class G amplifier ensures superior sound dynamics and efficiency, surpassing the performance of other amplifier classes. Every component has been meticulously selected to guarantee the best possible audio experience, resulting in an amplifier that blends precision with power.
Beautiful Screen
The SA35 comes with a 6.5" high-resolution display, showing album artwork and metadata, making it easy to enjoy music from your the comfort of your chair.

Your Music, Your Way
The system is compatible with most smartphones and tablets, supporting popular streaming services such as Apple Airplay, Google Cast, Spotify Connect, Tidal Connect, and Roon. With Wi-Fi connectivity and Dirac Live Room Correction, the SA35 offers flexibility, allowing you to tailor the sound to your space and speaker setup.
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.
