Introducing the LINA system
With a Network DAC, Headphone Amplifier, and Master Clock, LINA is the first dCS system purpose built for headphone listening.
The ultimate headphone solution by dCS
The essence of over 30 years of cutting edge technology from dCS now comes to a smaller package, designed specifically for headphone listening.
Network Ring DAC
The LINA Network DAC delivers extraordinary sound from all digital sources and audio recordings. Its design combines renowned dCS playback technologies – including the dCS Ring DAC and Digital Processing Platform – with new innovations, like a touch-screen display, a streamlined user interface, and a powerful flex-ridged circuit board, which delivers all the features you’d expect from a dCS system in a much smaller chassis.
Master Clock
The LINA Master Clock uses two quartz crystals to deliver a precise clocking reference for all audio formats and frequencies. When paired with the LINA Network DAC, it enhances all aspects of sound – from detail and imaging to rhythmic movement and flow. Each aspect of its design has been carefully crafted to protect against factors that can interfere with clocking signals, ensuring long-term stability and the utmost accuracy.
Headphone Amplifier
The LINA Headphone Amplifier is a powerful solid state, Class AB amplifier engineered to drive a vast range of headphones – from planars to sensitive IEMS – to their full potential. With its low noise floor, wide bandwidth, vast dynamic range, and excellent linearity, it delivers all of the sonic benefits you’d expect from a dCS product, and is designed to complement virtually any headfi setup.

The LINA product range features a suite of technologies that are unique to dCS, including the renowned dCS Ring DAC and the novel headphone processing platform, dCS Expanse. Through continuous innovation, dCS engineers have developed a technical DNA that overcomes the limits of conventional hardware and software to deliver a near-legendary sonic and technical performance across the entire dCS product range.
The Ring DAC
The Ring DAC is the proprietary digital-to-analogue conversion system found inside all dCS DACs. This integral component was designed from the ground up to minimise errors and variations that can cause distortion, and deliver a performance where all aspects of sound are resolved– from the finest of musical details, to the sense of time and harmonic movement. This pioneering design was first developed for dCS's professional audio products, and has been continually honed and refined ever since. Over three decades on, it remains renowned for its excellent linearity, class-leading distortion performance, and unique ability to capture the full range of artistry, detail and emotion contained within a recording.
Digital Processing Platform
The latest-generation dCS processing platform pushes the boundaries of measured performance in digital audio, using a powerful FPGA to deliver all of its functions and features, including audio processing, l/O encoders and decoders, oversampling, filtering, volume adjustment, user interface, and memory. Unrivalled in its intelligence and versatility, it provides complete control over signal processing operations. As the platform can be endlessly reconfigured and updated, it also lets dCS bring even the most ambitious ideas to life, and continue delivering new features, updates and enhancements throughout a product’s lifespan.
Expanse is a novel processing platform that brings the headphone experience closer to the studio listening experience. Its unique processing method replicates the effects of studio listening – where sound is projected into the space around us, rather than inside our heads – without altering the reverberation in a recording or affecting the system’s performance.
All dCS DACs, upsamplers and network music players feature their own internal clock systems. dCS also manufactures dedicated master clocks, which can be synced to a DAC or other product’s internal clock for enhanced precision and long-term stability. dCS delivers world- leading levels of accuracy and jitter control and ensure that no subtle details, timing or spatial cues are lost during the playback process.
All audio DACs require a range of filtering and processing operations in order to reconstruct audio wave forms. dCS has developed a range of bespoke filters for different audio formats and sample rates. This means customers with a dCS DAC are able to select the filter that best suits their chosen audio format and listening preferences.
