British hi-fi icon Roksan has elevated its revered Caspian series with the launch of the Caspian 4G Streaming Amplifier, a sophisticated all-in-one solution that seamlessly blends powerful Class AB amplification, advanced digital streaming, and analogue purity. Part of the fourth-generation Caspian lineup, this integrated amplifier builds on the brand’s decades-long heritage while embracing contemporary connectivity through BluOS premium multi-room streaming. Priced at approximately £3,999 / $5,000, it targets audiophiles seeking a single-component system without compromising on performance or versatility.
The Caspian 4G Streaming Amplifier represents Roksan’s “digital first” philosophy, integrating the acclaimed BluOS platform for high-resolution wireless streaming up to 24-bit/192kHz. It supports a vast ecosystem of services including Tidal, Qobuz, Spotify Connect, Deezer, and Amazon Music, alongside MQA decoding, Roon readiness, AirPlay 2, and Bluetooth aptX. HDMI eARC connectivity ensures effortless integration with modern TVs, delivering enhanced audio from movies and games with full remote control compatibility.
Euphoria amplification architecture
At its core lies Roksan’s proprietary Euphoria amplification architecture – a dual-mono Class AB design with separate power supplies for voltage and current stages, minimizing intermodulation distortion for cleaner, more dynamic sound. Paired with the innovative Rapture DAC, which employs differential current-conveyor topology and dual TI Burr-Brown chips in mono mode, the amplifier extracts exceptional detail and resolution from digital sources. An advanced balanced preamplifier section, complete with a high-quality moving magnet (MM) phono stage, caters to vinyl enthusiasts, while intelligent DSP options via the MaestroUnite app allow fine-tuning of tone, boundary, and speaker settings.
The result is a muscular yet refined performer: 105 watts per channel into 8 ohms (doubling to 200 watts into 4 ohms), capable of driving demanding loudspeakers with authority, precise imaging, and effortless dynamics. Reviews praise its transparent, full-bodied sound with a touch of warmth, excellent bass control, and a quiet background that reveals subtle musical nuances.
Design-wise, the Caspian 4G exudes premium craftsmanship with its extruded aluminum chassis, integrated heatsinks, and a high-contrast OLED display flanked by a haptic-feedback control dial. Available in black or silver finishes, it measures a substantial yet elegant footprint and includes a beautifully weighted aluminum remote.
