The world’s first, fully customisable and future-proof digital source for hi-fi enthusiasts…

…a high-performance offering unlike anything else on the market.

Edition Hub is a superior-quality enclosure, featuring an all-machined construction for improved rigidity, interior isolation, and elevated aesthetic appeal – with sleek sight lines, concealed joins and understated luxury at the fore.

The Edition Hub chassis consists of four plates, rigidly bolted together. The side pieces are flawlessly aligned with the base using pins, with four long bolts subsequently torqued-in for an exceptionally rigid fix, with a pleasing, precision fit and finish.

Providing both requisite heat management and high design appeal, the primary vent of Edition Hub is precision-cut into its aluminium plate lid. The vent itself is evocative of a wave, with each aperture cut at an angle, and only every second one machined all the way through. When viewed from different angles, this wave motif morphs and ripples – with myriad reflections projected from its various finishes and surfaces.

Edition Hub features a much-improved, eye-catching control dial. Its precision, turned-stainless-steel bearing ensures silky, tactile rotation when adjusting volume; and the photo-etched steel halo around its edge allows cool, sharp light to emanate from the one hundred individual LEDs beneath.

The all-glass fascia of Edition Hub is composed of mirrored spy glass; with the large-format display concealed behind it displaying crisp, clear information when necessary, and fading to total invisibility when not.

A broad range of connections on Edition Hub’s back panel ensures that it can receive, process and expertly deliver audio from any source imaginable; with a high-performance, integrated, analogue-to-digital conversion stage accepting anything from turntables to CD players, and a host of digital connections allowing connection from video streaming devices, games consoles, and Blu-ray players – ensuring you get the best possible sound from anything you connect to your Selekt DSM.

Edition Hub features, as standard, Linn’s all-new, exceptionally efficient, highly responsive, and precision-regulated power supply design – our best yet – Utopik.
