The Caspian 4G Power Amplifier is engineered to deliver uncompromising drive and power, whether used in stereo or mono-block configuration. It harnesses Roksan’s advanced Euphoria amplification architecture and precision-engineered analogue circuitry to ensure a transparent signal path that preserves every detail and dynamic nuance of the music. When paired with the Caspian 4G Streaming Pre-Amplifier, it forms a performance-focused duo. With fully balanced signal paths, together they unlock extraordinary clarity, authority and scale across all genres. Just add speakers…
Caspian Series 4G uses a new authoritative and intelligent Class AB amplifier architecture known as Euphoria. There is much more to sound quality than harmonic distortion and noise floor, although these remain important factors. Roksan prioritises intermodulation distortion and ensures that both harmonic and intermodulation distortion remain flat across frequency and load. The result is a sound that is purer, cleaner, and more detailed.
A power amplifier consists of two main sections that interact with each other but have very different characteristics. One section increases the voltage of the signal to the level required to drive the speaker, while the other increases the current needed to drive the speaker’s low impedance.
Both sections have been carefully analysed and improved by Roksan’s engineers. Within Caspian Series 4G, two separate bespoke power supplies are used, each independent of the other. Headroom on the voltage stage has been increased so that, regardless of how hard the amplifier is driven, this section does not voltage-clip.
This intelligent amplifier power supply architecture delivers exceptional clipping behaviour. It has been tuned through extensive listening sessions to extract the maximum sound pressure level from speakers before any perceptual degradation of audio occurs.
As a result, Caspian Series 4G sounds louder with more usable power, remaining clean, clear, and dynamically exciting. This provides exemplary levels of uncompromised power and scale, delivering total performance.
The number of components, capacitors, circuit boards, transformers, and amplifiers within a Caspian Series 4G product leaves little spare space inside its sleek and elegant enclosure. Every element is optimally positioned to minimise signal transfer issues, crosstalk, electrical interference, and noise, ensuring accurate reproduction of recorded sound.
Each unit is hand-built by Roksan’s expert in-house technicians in Rayleigh, Essex. Meticulously designed and engineered, Caspian Series 4G delivers total performance and an unparalleled listening experience.
Caspian offers extensive system configuration options. Using a Pre-Amplifier and Power Amplifier together provides clearer signal management, lower noise, and greater upgrade flexibility compared to an integrated amplifier. Separating the stages reduces noise and interference by isolating delicate signal processing from high-current power amplification.
Each unit is optimised for its specific function, with the Pre-Amplifier handling source selection and volume control while the Power Amplifier focuses solely on driving the speakers. This approach also allows independent upgrades and enables larger, dedicated power supplies for each function, minimising electrical interference and improving overall performance.
The pinnacle of system configuration and uncompromising sound quality is achieved by using multiple Power Amplifiers in mono-block format. Running Power Amplifiers in mono-block mode delivers commanding power, separation, and control that significantly surpasses an integrated amplifier. Each Power Amplifier handles a single channel with fully independent circuitry and power supply, virtually eliminating crosstalk. Mono-block operation supports increased power delivery, improved handling of demanding speaker loads, enhanced stereo imaging, and greater placement flexibility by allowing amplifiers to be positioned closer to the speakers. Electrical and mechanical interference are further minimised through isolated operation, benefiting grounding and heat dissipation.
The Caspian Pre-Amplifier and Power Amplifier system extends the acclaimed Caspian Series, delivering greater clarity and dynamic power to unlock the full potential of music playback. Powered by Roksan’s advanced Euphoria Class AB amplification, the Power Amplifier offers commanding performance in both stereo and mono-block modes, combining muscular output with refined control and carefully minimised distortion.
The Roksan Streaming Pre-Amplifier is the perfect partner, offering precise control and effortless usability. Featuring Roksan’s proprietary Rapture DAC with a dual-mono topology, it ensures exceptional signal integrity and timing. Together, the system forms a perfectly matched combination that allows every musical detail to shine through.

Roksan is a British manufacturer of high-end audio products founded in London. Formed in 1985, the company quickly gained a reputation for producing high-quality turntables, amplifiers, and other audio components. Roksan’s first and most iconic product, the Xerxes turntable, was launched the same year the company was founded. The Xerxes was notable for its innovative design, which aimed to eliminate the acoustic and mechanical flaws associated with traditional turntable designs. The result was a turntable design that set a new standard in the hi-fi industry and established Roksan as a serious player in the high-end audio market.
In 2016, Roksan was acquired by Monitor Audio, another prominent British audio company. This acquisition allowed Roksan to leverage Monitor Audio’s resources while continuing to innovate and produce high-quality audio equipment.
Today, Roksan is embracing the future by focusing on the needs of the connected consumer. As the audio landscape evolves, Roksan is integrating modern technologies to cater to a new generation of listeners who value both high-quality sound and seamless connectivity. This includes the development of products that support streaming services, multi-room audio setups, and smart home integration, ensuring that Roksan’s offerings are compatible with the latest platforms and devices.
