The Caspian Integrated Amplifier delivers total performance through its innovative Euphoria amplification architecture and advanced analogue connections, offering a flawless presentation of music via any source. The evolutionary Rapture DAC technology, for improved digital to analogue signal conversion, allows for a near perfect signal transfer, and ensures that the Euphoria amplification delivers total performance from whatever source a user connects.
Caspian 4G Series models are hand-built at Monitor Audio Group’s Headquarters in Rayleigh, Essex, United Kingdom.
Caspian Series 4G utilises Roksan’s powerful Rapture DAC technology; a differential current-conveyor topology, which allows more information to be extracted for the best possible analogue reproduction. This topology has several measurable advantages over the traditional approach to digital to analogue reconstruction using op-amp ICs. The current-conveyor has superior gain-bandwidth characteristics essential for faithful high-resolution audio reproduction. Moreover, despite being discrete (no off-the-shelf solution exists) it relies on a single circuit element for gain matching. Therefore, it can be utilised effectively in a discrete-component level solution.
Caspian Series 4G uses Roksan’s new authoritative and intelligent class AB amplifier architecture, Euphoria, which excels in power and finesse. Roksan has evolved the AB topology, with individual power supplies for the current and voltage amplifiers, this reduced interaction delivers purer, more detailed and cleaner sound.
Caspian Series 4G’s innovative volume control encapsulates the best of both the digital and analogue worlds. A hybrid digital-analogue volume control algorithm leverages powerful digital signal processing to facilitate tone controls and system matching.
Accessed via the MaestroUnite app, Caspian Series 4G’s intelligent DSP engine optimises a user’s listening experience through the application of four key technologies: Intelligent Tone, Intelligent Boundary, Intelligent Speaker and Intelligent Phono. In combination, these technologies allow users to fine-tune their listening experience to their environment for the best possible results.
Caspian Series 4G’s new monochrome high-contrast OLED display frames the intuitive single point of control user interface more clearly and larger than ever before. Customisable input icons allow easy source selection, while a new progress indicator displays features such as track length.

With its effortless dynamics, sense of realism, drama and control, I can think of few amps I’ve enjoyed listening to as much as the Caspian 4G of late, and all with price tags well north of the Roksan, showing how great value it is. ‘Affordable reference’ is perhaps the best way to sum up what Roksan has achieved with the Caspian 4G, and for that it should be celebrated. more...
