The Cayin CS-805A integrated amplifier features the renowned WE6SN7 output triodes in its voltage amplifier stage, with exquisite 300B tubes in the driver stage working in tandem with the 805A output tubes.
In addition to three pairs of line inputs, the CS-805A offers an additional pair of pre-inputs, enabling seamless integration with an external preamplifier. This versatility allows the amplifier to be used as a standalone power amplifier or easily incorporated into home theater systems with AV processors.
The CS-805A is equipped with meticulously crafted point-to-point silver wiring, ensuring exceptional signal transmission and long-lasting durability.
For ease of use, the amplifier includes an onboard bias meter, making it simple for users to adjust the bias settings for optimal performance. The CS-805A also allows users to fine-tune the negative feedback, providing the ability to tailor the sound characteristics to personal preferences.
The amplifier includes a high-quality headphone output that delivers superb audio performance, capable of driving most headphones with impressive fidelity and offering a deeply immersive listening experience.
The CS-805A simplifies bias adjustment for the 805 tubes through its built-in bias display, enabling users to easily fine-tune settings. Additionally, the amplifier features a hum balance control, allowing external adjustment of the 300B tubes for enhanced convenience and customization.
The negative feedback value can be adjusted between 0 and -3dB via the remote control, giving users the flexibility to shape the amplifier's sound to match their unique listening preferences. At 0dB, the amplifier provides an open, detailed, and fluid sound, while -3dB delivers a more controlled, precise, and smooth playback.
To protect the longevity of the tubes and sensitive components, the CS-805A includes soft start circuitry and high-voltage delay, working together to ensure extended lifespan and reliable performance.
The amplifier is also equipped with easily accessible high-voltage fuses, offering immediate protection to the circuitry in the event of a tube failure. The CS-805A's construction relies on the finest point-to-point wiring for optimal performance and reliability.
Only premium components are used in the CS-805A's build, including Alps volume control, porcelain tube sockets, carefully selected capacitors, and carbon film resistors known for their excellent audio quality. A large toroidal transformer ensures a stable power supply even during demanding musical passages, while the EI output transformers with wide bandwidth provide optimal coupling with connected speakers, ensuring outstanding sound reproduction.
