CH Precision is a Swiss company dedicated to the design, manufacturing and commercialization of ultra high-end audio products under the 'CH' brand. Fully designed and manufactured in Switzerland, CH products stand out for their exceptional audio performances and build quality. Although the company is still fairly young, the team has a solid experience and a proven track record in designing high performance, high-end audio from its previous activities with ABC-PCB (high-end audio OEM) and ANAGRAM Technologies (audio DSP technologies) among others.

Whereas product design is fully done in-house, manufacturing is handled by local business partners. The enclosures are machined by specialized Swiss companies active in the luxury watch industry. Printed circuit boards and the units' final assembly are handled by ISO certified partners in the Swiss Alps area. Working hand in hand with highly skilled, dedicated people allows CH Precision to deliver a consistent perfect quality to all its products.

The team has an unrivaled experience in the high-end audio industry covering both digital & analog board design, DSP software, FPGA programming as well as mechanical design. This is confirmed by the specialized press recognition and the numerous awards received by all CH products. CH Precision also closely collaborates with Technology Institutes and Universities to keep up-to-date with the latest research and technological developments. The company strongly believes that correctly applied technology confirmed by in-depth measurements at the lab and finally a thorough listening is the way to improve the art of audio reproduction.

CH products provide a unique blend of ultimate audio performance, timeless design and build quality. Based on the latest technologies and open for future upgrades due to its modular approach, they make every audiophile's heart beat faster. Last but not least, the company takes enormous pride in correlating superb audio performance with excellent measured performance and reliability.




D1 SACD&CD Transport/Player

CH Precision's D1 Reference grade SACD&CD unit exemplifies state-of-the-art Swiss precision and utmost dedication to faithful musical reproduction.

Built around the Esoteric VMK-5 VRDS SACD&CD pick-up mechanism, the D1 offers a fully modular and evolutive architecture based on optional slot-in boards for its audio outputs. Almost any configuration ranging from a simple stereo analog only player to a multi-channel purely digital drive is allowed.

The user interface is based on an ergonomically designed dual concentric rotatory knob with push function and feedback is given by a color-programmable high-definition AMOLED display. A custom infrared remote control allows access to the D1's most common functions.



C1 Reference Digital to Analog Controller

Designed for the true music lover, the C1's apparent simplicity hides highly sophisticated technological solutions with the single goal of recreating the full musical experience. This emotion can only be achieved when both level and time information are properly reconstructed from the digital data. And this is what the C1 is all about...

The C1 is based on a fully modular, future-proof architecture. Up to three inputs boards include standard digital inputs complemented by the proprietary CH-Link interface. Optional streaming audio inputs as well as line-level analog inputs enable the use of the C1 as a full featured preamplifier thanks to its integrated volume control.

A reference grade linear power supply (with <1W power consumption in standby mode), sophisticated mechanical chassis design and full USB based firmware update also contribute the C1's uniqueness, for now and for any future format!



A1 2-channel Power Amplifier

As the driving force behind recreating the full musical experience, the task of the power amplifier may seem desperately simple but is indeed highly complex. Achieving our simple goal of ”add nothing, remove nothing” to preserve the full musical emotion has resulted in a ground breaking new amplifier topology. Housed in a chassis similar to the C1 and D1, the A1 sets new standards in terms of performance, flexibility of adjustments, industrial design and pure enjoyment.

The A1 is based on a novel proprietary amplifier architecture which optimizes the critical matching of the amplifier with the speaker. It can be operated either as a stereo amplifier (2x 100WRMS under 8Ω), as a monaural bi-amping amplifier (2x 100WRMS under 8Ω) or as a bridged amplifier (1x 350WRMS under 8Ω).

A sophisticated mechanical chassis design and full USB based firmware update support contribute to make the A1 a real long term enjoyment.


L1 Dual Monaural Line Preamplifier

The uttermost quality of a preamplifier is its transparency. The source is selected and the volume is applied, however the original audio characteristics and signal dynamics are fully retained. The L1, a dual monaural analog line level preamplifier, was developed using this approach. It is a pure class A, ultra low noise, high bandwidth, fully balanced transistor based design. It provides the shortest path between input and output, maintaining the highest speed, transparency and musicality, allowing the L1 to become a truly exceptional preamplifier.
