Cayin CS-150A Integrated Valve Amplifier

Introducing the stunning CS-150A

Powerful.  Vibrant.  Flexible.  Beautiful.

The Cayin CS-150A integrated vacuum valve amplifier underlines its exceptional quality with a six-layer hand-lacquered surface with impressive aesthetics and a deep gloss. But it's the technology that makes the CS-150A something truly special. Selected tubes of the type Tung-Sol 6SN7GTB are used for the input and driver stage. Four Tung-Sol KT150s or optionally four KT120s are used as high-performance output stage tubes. The voltage is rectified by an RCA 22DE4 NOS tube.

Three switches enable the sound to be matched to your individual taste or adaptation to your speakers. This includes switching between triode and ultra linear operation. So you have the choice between delicate, detailed harmonies, liquid and holographic reproduction, which is ideal for voices and string instruments. You can also increase performance and dynamics with controlled bass reproduction in ultra-linear operation.

The output power is a tight 2 x 55 watts sine in triode mode and increases to a remarkable 2 x 100 watts in ultra linear mode. This is an extreme output for a thoroughbred tube amplifier, and that's not all about customisation. A variable bias (high / standard) is also available on the CS-150A: Round mids and basses characterise the position “Bias high”, precise musical structure the position “Standard”.

The adjustment options are not exhausted there. You can even choose the negative negative feedback in two stages. This allows soft, natural reproduction in the "Low" position or tight and controlled in the "High" position.

Balanced XLR and unbalanced RCA inputs ensure maximum connectivity.

The broadband output transformers were specially wound for the requirements of the CS-150A and selected in pairs. A powerful toroidal transformer ensures a stable power supply, reduced output resistance and optimal performance.

The Cayin CS-150A is also characterised by careful point-to-point wiring with high-quality, shielded, silver-coated cables.

The input selection memory function proves to be a comfort plus. After switching on, the last selected input is automatically activated. A soft start circuit ensures optimum protection of the tubes used. The high-quality metal remote control provides access to the numerous functions of the Cayin CS-150A. The Cayin CS-150A is available with a silver or black front.
