Roksan Caspian 4G Streaming Amplifier Review: BluOS, Euphoria & Rapture DAC Unleashed

Welcome to our in-depth Roksan Caspian 4G Streaming Amplifier Review, where we explore the BluOS-enabled powerhouse that redefines modern high-fidelity streaming. Bridging top-tier digital convenience and analogue purity, the Caspian 4G is Roksan’s latest statement of engineering prowess.

Exquisite Craftsmanship & Industrial Design

The Caspian 4G’s sleek, bead-blasted aluminium chassis exudes quality from every angle. The gently curved fascia, the crisply machined volume knob and the minimalist display combine to create an amplifier that sits gracefully in any living space. Available in both Deep Black and Satin Silver finishes, it’s as much an objet d’art as it is a high-performance component.

Feature-Rich, User-Centric Operation

At the heart of this amplifier lies BluOS, the premium multi-room streaming platform supporting resolutions up to 24-bit/192kHz. Native integration with services like Tidal, Qobuz and Spotify Connect sits alongside HDMI eARC for effortless connection to your TV, MQA decoding, Bluetooth aptX and AirPlay 2 – a truly modern digital-first DNA. For vinyl enthusiasts, the built-in Moving Magnet phono stage brings archival recordings and new pressings to life with surprising depth.

Control is elegantly handled via Roksan’s MaestroUnite app. From advanced configuration to OTA firmware updates, you can group zones, tweak EQ settings or launch MQA files all from your smartphone.

Powerful Amplification & Reference-Grade DAC

Caspian’s Euphoria architecture employs dual independent amplification modules, delivering effortless dynamics and tight, controlled bass. Complementing this is the revolutionary Rapture DAC technology, which elevates your digital-to-analogue conversion with remarkably low noise and distortion. Whether driving compact bookshelf speakers or floor-standers, the Caspian 4G conjures a stable, holographic soundstage that remains utterly musical.

Connectivity for Every Setup

Roksan haven’t skimped on connectivity. Alongside multiple line-level RCA and balanced XLR outputs, there’s a dedicated subwoofer output, a moving magnet phono input and HDMI eARC for home theatre integration. The ergonomically designed aluminium remote ensures you can command volume, source selection and presets without reaching for your phone.

Who Should Consider the Roksan Caspian 4G?

If you’re an audiophile seeking a single-box solution that marries audiophile-grade amplification with cutting-edge streaming, the Caspian 4G is a compelling choice. Vinyl lovers will appreciate the built-in phono stage, while digital devotees will marvel at BluOS’s seamless multi-room capabilities. It’s equally at home in a dedicated listening room or as the nerve centre of a stylish living space.
