ROKSAN CASPIAN SERIES 4G STREAMING PRE-AMPLIFIER AND POWER AMPLIFIER LAUNCHED
British HiFi brand Roksan has expanded its Roksan Caspian Series 4G range with the introduction of two new separates: the Roksan Caspian Series 4G Streaming Pre-Amplifier and Power Amplifier.
The additions complete the Roksan Caspian Series 4G line-up, which now consists of four models: Streaming Amplifier, Integrated Amplifier, Streaming Pre-Amplifier and Power Amplifier.
ROKSAN CASPIAN SERIES 4G SYSTEM EXPANSION
The new Roksan Caspian Series 4G Streaming Pre-Amplifier and Power Amplifier are designed to offer system flexibility, allowing users to configure everything from a straightforward stereo setup to a mono-block arrangement. Both units are hand-built at Monitor Audio Group’s headquarters in Rayleigh, Essex, and follow the company’s Transparent Design Philosophy, which aims to balance technical performance with practical usability and restrained industrial design.
ROKSAN CASPIAN SERIES 4G STREAMING PRE-AMPLIFIER
At the centre of the new launch is the Roksan Caspian Series 4G Streaming Pre-Amplifier, which combines network streaming with a fully balanced analogue pre-amplifier stage. Streaming duties are handled by BluOS, with support for high-resolution audio up to 24-bit/192kHz, multi-room playback, and access to major streaming services, alongside playback of locally stored music. The unit is also Roon Ready.
Wireless connectivity is managed via internal, custom-designed Wi-Fi and Bluetooth antennas, intended to reduce interference while keeping the external design uncluttered. The pre-amplifier section uses a ground-switching input design to reduce crosstalk between connected sources, supported by multiple dedicated power supplies aimed at lowering noise across the signal path.
ROKSAN CASPIAN SERIES 4G POWER AMPLIFIER
The Roksan Caspian Series 4G Power Amplifier is designed for use in either stereo or mono-block configurations. It employs Roksan’s Euphoria Class AB amplification architecture, with separate voltage and current amplification stages and independent power supplies. According to Roksan, this approach is intended to reduce interaction between stages and improve overall signal clarity.
The power amplifier also features carefully tuned soft-clipping behaviour, developed through listening tests, with the aim of maintaining composure at higher listening levels without abrupt distortion.
ROKSAN CASPIAN SERIES 4G CORE TECHNOLOGIES
Across the Caspian Series 4G range, including the new Roksan Caspian Series 4G Streaming Pre-Amplifier and Power Amplifier, Roksan employs its Rapture DAC architecture. This uses a differential current-conveyor topology rather than conventional op-amp-based designs, with the aim of improving bandwidth performance and analogue signal reconstruction.
Volume control is handled by a hybrid digital–analogue system, allowing for fine adjustment and integration with tone controls and system matching functions. A built-in DSP engine, accessible via the MaestroUnite app, offers features such as Intelligent Tone, Intelligent Boundary, Intelligent Speaker and Intelligent Phono adjustments to help tailor performance to room and system conditions.
ROKSAN CASPIAN SERIES 4G USER INTERFACE AND CONTROL
Both new models feature a high-contrast monochrome OLED display, designed to present source selection and playback information clearly. Input icons can be customised, and a progress indicator provides basic track information during playback.
System setup and advanced configuration are handled through the MaestroUnite control app, which provides access to input settings, gain matching, balance control, standby options and DSP features. The app is shared across Monitor Audio Group electronics, aiming to provide a consistent control experience.
ROKSAN CASPIAN SERIES 4G BUILD AND CONNECTIVITY
The physical design of the Roksan Caspian Series 4G Streaming Pre-Amplifier and Power Amplifier builds on the visual language introduced with the Attessa range, featuring machined aluminium details, custom extruded heatsinks and a low-profile chassis. Internal antenna placement is intended to maintain wireless performance without external aerials.
Analogue connectivity includes fully balanced signal paths, while the summary feature list also confirms the inclusion of a dedicated MM and MC phono stage with calibrated RIAA equalisation across the Caspian Series 4G platform.
ROKSAN CASPIAN SERIES 4G STREAMING PRE-AMPLIFIER AND POWER AMPLIFIER PRICING AND AVAILABILITY
The Roksan Caspian Series 4G Streaming Pre-Amplifier is priced at £3,500 per unit, while the Roksan Caspian Series 4G Power Amplifier costs £3,000 per unit. Availability is confirmed from January 2026.
HiFi PiG Says: Great to see the Roksan Caspian 4G Series now complete with these two new products.
