    This model is a serious and substantial upgrade to the famous 860 model. Working in the ultra linear mode, each Cayin 880 mono power amp boosts 75 watts of stable power. An array of four Russia made ELECTRO HARMONIX 6550EH valves ensures rich dynamic sound reproduction. In the triode mode (switchable at the top panel) this pair of amplifiers works extremely linear and shows no signs of sonic harshness. You are free to choose your speakers nearly without any limits. By using the bias level indicator at the front plate, you can easily check and adjust the bias voltage of each single power valve all outside.

    The owner may adjust the bias of the power valves by using gain controls and a high precision VU meter on the outside of the amplifier. To control the input voltage of the power stage, it uses 6CG7 valves, which improve the stability of the four ELECTRO HARMONIX 6550EH for each channel. This makes the frequency range of the power stage more linear. That may sound very complex to anyone not involved in the secrets of valve design, but you don’t need to be a technical expert to feel the beauty of sound reproduction, which is possible by connecting it to your speakers.
