A Visit to Where Precision Becomes Music

There are factories that assemble products, and then there are places where philosophy, engineering, and craft quietly converge. When Definitive Experts Zach and Hans traveled to Switzerland to visit CH Precision, it became immediately clear which category this company belongs to.

Located in Préverenges, Switzerland, just outside Geneva, CH Precision operates with a level of intentionality that mirrors the performance of their components. This was not a tour designed to impress with spectacle. Instead, it revealed something far more meaningful: a culture built on control, continuity, and a deep respect for both music and engineering.

Day One: Listening, Learning, and the Anatomy of Precision

The visit began at CH Precision’s offices with introductions and extended listening sessions. Zach and Hans spent time exploring the flexibility and modularity that defines CH’s digital architecture—comparing configurations of the C1.2 DAC and the flagship C10, along with the D1.5 and D10 CD/SACD transports.

What stood out wasn’t just sonic refinement, but the sheer intentionality behind every option. Each step up the range, each added chassis, delivered the kinds of improvements we recognize immediately in truly great systems: a lower noise floor, improved tonal balance, greater dynamic expression, and an expanded sense of space. More there, without ever tipping into excess.

The fully realized digital stacks were nothing short of stunning. As additional DAC and power supply modules were introduced, the system didn’t simply become “better” in a hi-fi sense—it became more convincing, more human.

The D10 CD/SACD transports: Digital, Reconsidered

One moment stood above the rest.

The D10 CD/SACD transports, paired with a fully loaded C10 DAC, delivered something Zach described as entirely new to his experience with digital playback. While the D1.5 is exceptional in its own right, the D10 introduced a sense of realism and humanity that went far beyond cleaner transients or added detail.

It wasn’t just that the sound was clearer.
It was that the person behind the performance came through.

Vocals carried physical presence. Instruments felt embodied. The artist wasn’t simply rendered accurately—they felt present. Not just in the room, but emotionally and spatially. It was a level of connection Zach hadn’t experienced before, and one that lingered long after the session ended.

If there is such a thing as a digital system that dissolves the boundary between listener and performance, a D10 feeding a full C10 stack may be the closest expression of it yet.

From there, the visit moved north to Le Locle, a small town in the Jura Mountains and home to the machine shop responsible for CH Precision’s casework. This facility alone told a powerful story.

Raw materials enter one door.
Finished, assembled casework leaves another.

Inside, the shop machines, finishes, engraves, anodizes, and assembles CH Precision’s enclosures entirely in-house. Aluminum, stainless steel, titanium, even plastics—all handled with the same exacting standards. Several of the CNC and finishing machines were custom-designed specifically to achieve tighter tolerances and more consistent surface finishes than off-the-shelf equipment could provide.

Laser engraving. Glass blasting. In-house anodizing—something rarely seen even in high-end metal shops. Finished parts are assembled into completed casework before being delivered back to CH Precision multiple times per week.

While the shop isn’t owned outright by CH Precision, the relationship is deeply integrated. CH has invested directly in key machines, and roughly half of the shop’s output supports CH products. The remainder serves industries where precision is non-negotiable: medical devices and Swiss watchmaking.

The message was clear: the same standards applied to life-saving equipment and precision timekeeping are being applied to audio.

Day Two: The People Behind the Products

Back at CH Precision headquarters, Zach and Hans toured the offices and met the people who bring these components to life—engineers, programmers, designers, assemblers, and service technicians. The walls are lined with favorite artist posters. Music isn’t an abstract goal here—it’s a shared obsession.

CH Precision designs and engineers everything in-house: electrical, mechanical, software, firmware, and system architecture. Circuit boards are manufactured locally (within 100 km), tested, validated, and assembled on site. Much of the internal wiring is also completed in-house to maintain consistency and control.

Critical components—including semiconductors and chips—are stored in climate-controlled environments, with temperature and humidity carefully regulated. (Humidity, they explained, is one of the greatest enemies of long-term component reliability.) They even maintain a Faraday enclosure to test static discharge resistance on parts.

Perhaps most telling of all is continuity. Several engineers have worked alongside Florian Cossy—the “C” in CH Precision—since the company’s founding, or even earlier ventures. This is a team built for the long term.

Service is handled entirely in-house, with fast turnaround and long-term support as a core value. These are not disposable products. They are designed to evolve.

Why This Matters

Visits like this reaffirm why Definitive partners with brands like CH Precision. What we heard in the listening room was directly reflected in what we saw behind the scenes: control, modularity, precision, and respect for the music.

CH Precision doesn’t chase hype. They build systems that reward careful setup, thoughtful upgrades, and long-term ownership. And after seeing how deeply every detail is considered—from machining and materials to software and service—it’s easy to understand why their components feel less like “gear” and more like instruments.

This trip wasn’t just about learning how CH Precision products are made. It was about understanding why they sound the way they do—and why, for the right listener, they can become a lifelong reference.

If you’re curious to explore what CH Precision can bring to your system, we’d love to share that experience with you.

Because sometimes, the path to extraordinary sound starts with seeing where it’s born.
