The purest expression
Powerful and graceful too, the Rossini renders music with the utmost precision and care, delivering a fluid and natural sound without the slightest hint of harshness or glare. From the softest strings to the sharpest brass, and the quietest intake of breath, it unearths each aspect of a recording to reveal a performance that feels layered, lifelike and whole.

No matter how complex the music, it never loses its composure, or its sense of rhythm and flow, tracking even the swiftest shift in dynamics and pace with a sense of utter control. With its unshakable focus and astonishing insight, it presents a holographic view of a recording, and the atmosphere and space in which a performance takes place.

Designed and hand-assembled at our headquarters in Cambridgeshire, England, the Rossini is born from meticulous craft, exhaustive development and an obsessive attention to detail - a relentless pursuit of musical purity that has inspired us to push the limits of sound reproduction.

Combining robust engineering with an elegant aesthetic, the Rossini is built to withstand even the most intensive use and deliver a truly immersive sound at all levels and outputs. With its flexible, future-proof design, it’s a system that can grow and evolve, delivering a state-of-the-art listening experience for years to come.

An esteemed cohort to our renowned Vivaldi system, it features our proprietary Ring DAC system, digital processing platform, and clocking architecture - a combination of hardware and software that is unrivalled in its sonic and technical performance.

New for 2022, the Rossini APEX benefits from the latest generation dCS Ring DAC APEX hardware. This major upgrade brings a range of measured and sonic improvements, allowing us to further enhance the performance of this much-loved and multi-award-winning system, and provide an even richer experience for listeners.

APEX: A Closer Look

Learn more about the development of our new Ring DAC™ APEX hardware and the various benefits it delivers for listeners. This week, we're celebrating the launch of our latest innovation with an in-depth look at the creation of the dCS Ring DAC APEX. Following the launch of our APEX short film, we've published an article which offers a deeper insight into our development process and the steps we've taken to further enhance the Ring DAC's performance. The article features insights from dCS Managing Director David Steven and Director of Product

• Development Chris Hales and explores the following topics:

• How we enhanced the Ring DAC’s analogue performance, including specific modifications made to the Ring DAC’s hardware.

• How we approached the development process, from initial exploration through to listening tests.

• The subjective and measured benefits of APEX.

• Our motivations and objectives.
