Cayin CS-805A Tube Integrated Amplifier – Single-ended Class A Tube Amplifier

A new stereo integrated amplifier expands the Cayin Audio range, and how could it be otherwise, based on tube technology. Once again, the new Cayin CS-805A Tube Integrated Amplifier proves that these solutions can also offer sufficient performance.

The Cayin CS-805A Tube Integrated Amplifier can be loud, according to Cayin Audio, which wants to express with this description that this new amplifier is capable of delivering powerful sound, even though it is a tube-based solution.

Tube and power do not have to be a contradiction in terms, they are convinced.

Cayin CS-805A Tube Integrated Amplifier – Powerful two times 50 watts

According to the company, the new Cayin CS-805A Tube Integrated Amplifier is capable of producing two times 50 watts and relies on classic WE6SN7 output triodes for the voltage amplifier stage of the integrated amplifier. In the driver stage, 805A glass bulbs of the 300B type are used for the output tubes.

Solid interface equipment

The new single-ended Class A tube amplifier has three inputs, of course designed as a pair of cinch sockets. In addition, there is another pair of cinch sockets designated as Pre In.

For connecting the loudspeaker systems, three pairs of solidly designed, encapsulated screw terminals are available, depending on whether the loudspeakers have an impedance of 4 or 8 ohms.

Simple operation

The main switch is located on the front, a rotary encoder for input selection on the right and the volume control in the centre. Status LEDs provide information about the most important parameters of the Cayin CS-805A single-ended Class A tube amplifier.

The scope of delivery also includes an infrared remote control, whereby the manufacturer states that it saves the last operating state of the amplifier after it has been switched off.

In addition, the value of the negative feedback can be selected directly on the remote control between 0 and -3 dB, so that the sound of the amplifier can be adjusted to a certain extent to the individual listening habits.

At a setting of 0 dB, the Cayin CS-805A Tube Integrated Amplifier shows a very open, fluid sound with a lot of details, as the manufacturer describes it. At -3 dB, the sound is said to be smooth, precise and controlled.

Users can easily adjust the bias of the 805 tubes via the integrated bias display. With a so-called hum-balance control, the user can also adjust the 300B tubes to the optimal level from the outside, according to the manufacturer’s promise.

Integrated headphone amplifier

The new Cayin CS-805A Tube Integrated Amplifier also offers another interesting feature, namely an integrated headphone amplifier. This is directly accessible via a 6.3 mm stereo jack on the front and is said to provide more than enough power to effortlessly drive a wide variety of headphones.

Sophisticated details and high-quality components

Soft-start circuitry and high-voltage delay to protect the amplifier work together to extend the life of the tubes and sensitive components.

Easily accessible high-voltage fuses are used to protect the amplifier. In the event of a tube failure, the fuse reacts immediately, protecting the circuitry which, according to the manufacturer, uses the finest point-to-point wiring.

Only high-quality components are used, Cayin Audio states. These include an Alps volume control, porcelain tube sockets, selected capacitors and carbon film resistors with the highest audio quality. A large toroidal transformer guarantees a stable power supply even with impulsive music. The EI output transformers ensure optimum coupling with the loudspeakers used with a wide bandwidth.

The new Cayin CS-805A Tube Integrated Amplifier should be available from Cayin Audio as early as these days. The price for this solution is stated at € 6.400,-. It will be offered in black and silver.

Getting to the point

The new Cayin CS-805A Tube Integrated Amplifier proves once again that an amplifier based on tube technology is capable of delivering sufficient power for a variety of different loudspeaker systems. After all, two times 50 watts are available with this new solution from Cayin Audio.
