The Cayin CS-845M Tube Power Amplifier combines exquisite craftsmanship with cutting-edge technology to deliver an exceptional audio experience. Hand-made construction features the finest point-to-point wiring, ensuring optimal signal integrity and minimal interference.

Advanced Transformer Design

This amplifier incorporates an EI output transformer with a wide bandwidth, complemented by a specially designed toroidal transformer for power supply. This combination guarantees robust performance and dynamic sound reproduction.

Innovative Tube Configuration

The preamp stage utilizes a single 6SN7 tube for precise voltage regulation, while two additional 6SN7 tubes are employed for voltage amplification. At the heart of the amplification stage lies the TJ Full Music 300B with a porcelain base, driving the 845 vacuum tube for Single-ended Class A amplification. This configuration ensures rich, warm audio reproduction, ideal for audiophiles.

Customizable Feedback Options

Designed with flexibility in mind, the CS-845M offers switchable negative feedback settings: NFB -0dB, NFB -2dB, NFB -3dB, NFB -4dB, and NFB -5dB. This allows users to tailor the amplifier’s performance to suit different listening environments and preferences.

User-Friendly Adjustments

Convenient user bias and hum balance adjustments are easily accessible on the top of the amplifier, featuring a true ampere meter for precise monitoring. The amplifier also supports both BALANCE and RCA input functions for versatile connectivity.

Premium Components

High-quality German WBT top-grade speaker terminals, USA Multicap capacitors, and Japanese Takman carbon film audio-grade resistors ensure optimal sound quality and reliability. The high-grade gold-plated porcelain tube socket enhances connection stability, while thickly silver-plated signal cables and connectors further elevate performance.

Enhanced Durability and Protection

The CS-845M features a time-delay power supply for both high/low voltage and preheated filament, prolonging tube life. An easily-installed aluminum tube cover offers protection while maintaining aesthetic appeal.

The Cayin CS-845M Tube Power Amplifier stands as a testament to superior engineering and design, delivering a high-fidelity audio experience that captivates discerning listeners.
