CH Precision

Dual monaural twin-chassis High End class phonostage - the latest introduction to CH Precision flagship 10 Series.

Upsampling DAC with volume control and Linearized R-2R with four PCM1704 chips per channel offers PCM 24 bits, 705.6kHz or 768kHz, DSD via DoP up to DSD512.

Fully discrete, balanced Dual Monaural line-stage (preamplifier) with heavily regulated and filtered power supplies and extreme wide-bandwidth frequency responses.

Doubled the power supply capacity (vs. M.1.1) High End amp offers bandwidth up to 500kHz and delivers 2 x 550 Wt (4 Ohms load)!

With important parameters adjustable from the CH-Control App, the P1 phonostage can handle up to three tonearms, and offers a combination of both current and voltage-sensing inputs for best music reproduction.

The next generation reference-class digital-to-analog converter uses PEtER oversampling algorithm, and 16 x PCM 1704 R2R DACs in a dual differential, sequential DSQ Phase Array topology.

The L10 retains a fully discrete, balanced and complementary design, ultra-short signal transmission paths, highly adjustable and filtered multi-stage power supplies, wide bandwidth, high rise rate, and the L1 DC topology. It includes the same sophisticated R-2R volume control, sophisticated DC detection and suppression circuitry, and software controls.

Two mono DACs and a switchable pre! The work is carried out according to its own algorithm – a powerful processor (2.4 GFLOPS DSP) is used, which translates all signals into 768 kHz (705.6 kHz for DSD) RFM. A number of experts rate the sound as "the end of the search for the best DAC in the world."

The main difference from its predecessor was its own MORSe (Mechanically Optimized Reading System) design mechanism. The slides in the drive are separated from the body by a special suspension, which eliminates vibrations during the rotation of the discs. The chassis attached to the bottom of the device through a vibration-proof plate with four support points helps to minimize vibrations and vibrations.

CH Precision is an M1.1. 2 x 200 W 8 Ohm power supply, the operation of the driver part is, of course, in pure class A, a fully discrete element base, a 2,200 VA transformer, a 250,000 UF capacitor bank – it can take a long time to list.

The amplifier uses a powerful 1,700 VA transformer - it is housed in its own case, which is completely vibration-free and shielded. The power supply uses ESR capacitors, but they are not present in the signal circuit. The entire analog part of the device is assembled on discrete components. Feedback is configured from the front panel in increments of 20%.

The integrated I1 amplifier is arguably the most complex project that CH Precision has ever undertaken and the most versatile product we have ever produced. Imagine the basic qualities and capabilities of the C1 DAC controller and amplifier 1 combined in one box. Now add the selected parts of the linear scene L1 and add the background scene option P1, they are all combined into one standard CH chassis, and you will begin to understand the picture.
