Cambridge Audio Alva ST Belt Drive Turntable with Bluetooth® aptX HD

A high-mass, low-resonance tonearm, die-cast aluminium platter, and belt-drive motor with electronic speed control work together to minimise vibration, enhance tracking accuracy, and reduce unwanted resonance—so you hear nothing but your music.

Vinyl, made easy

Alva ST blends classic analogue warmth with modern convenience. Whether streaming wirelessly over hi-res Bluetooth or connecting to your amp via its built-in phono stage, this turntable delivers stunning sound with minimal setup. Just place it, plug it in, and drop the needle.

Vinyl streaming, modern simplicity

A smooth drive with total control

Alva ST’s belt-drive mechanism ensures smooth, consistent playback. Electronic speed control lets you switch effortlessly between 33 1/3 and 45rpm at the push of a button—no need to lift the platter or adjust belts manually.

Precision aluminium platter

The 17mm die-cast aluminium platter, CNC-finished for total flatness, is paired with a 5mm rubber mat to absorb unwanted resonance. This means cleaner, clearer sound and better protection for your records.

High-performance tonearm

Designed for performance and flexibility, Alva ST’s high-mass, low-resonance tonearm extracts maximum detail from your records. The detachable aluminium headshell makes swapping cartridges easy, while the anti-skating dial allows for precise adjustments.

Built to last

With a 1mm aluminium top plate, vibration-absorbing EVA layer, and an MDF base, Alva ST is engineered for durability and optimal sound quality. Weighing in at 9kg, it’s solid, stable, and built to handle a lifetime of vinyl playback. Your collection can last a lifetime, so why shouldn’t your turntable?

Timeless style

Finished in Lunar Grey aluminium with a sleek matt black plinth, Alva ST shares the minimalist aesthetic of our best-selling EX and CX Series hi-fi components. It’s designed and engineered in London for those who appreciate both form and function.

Stay dust-free

Alva ST comes with a hinged dust cover to protect your turntable when not in use. It’s easy to raise, lower, remove, and reattach. It keeps your deck pristine while offering flexibility in how you use it.
