Rapture DAC

Caspian Series 4G features Rapture DAC technology, a differential current-conveyor topology. Roksan has designed it differently because it’s better this way – it 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 (DAC) 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. Rapture represents a completely fresh way of taking the digital signal and converting it into analogue.

Key DAC Spec

• Dual-Mono Topology: Each channel is derived by the summation of two switched current sources to improve linearity with the current-to-voltage transform and filtering by the discrete current conveyor.
• LVDS (low-voltage differential signalling) transfer of sensitive timing and digital audio information: time-aligned signals can corrupt the operation of adjacent analogue circuits and are themselves easily and irretrievably upset. Roksan has engineered a network of matched transmission lines for perfect digital signal integrity with no associated noise footprint. Delivering the most accurate stereo imaging, breathtaking resolution and an inky-black quietness between musical passages.

Powerful DSP engine

Roksan’s desire for total performance is aided further by the integration of Caspian Series 4G’s powerful DSP Engine. This vital element delivers the intelligence and flexibility that helps the user tailor their listening experience to their environment and taste. It ensures Caspian 4G fully realises the accurate replay of the original recording, just as the artist intended – from the studio, into your home.
The power of the Roksan DSP Engine is accessed through the intuitive MaestroUnite app, where a user can optimise their listening experience using four key technologies:

• Intelligent Tone
• Intelligent Boundary
• Intelligent Speaker
• Intelligent Phono
