ARTICLE N° 123770
Cayin presents the Soul 170i Bois, a tube-based integrated stereo amplifier designed for audiophiles seeking detailed musical reproduction and high power output. Its Class AB design is based on four Tungsol KT170 output tubes combined with 6SN7, ECC83S and 17AX4GT tubes, selected to ensure stable operation and balanced sound reproduction.

Capable of operating in triode or ultra-linear mode, it easily adapts to listening preferences and speaker requirements. Triode mode delivers up to 2 x 75 watts, whilst ultra-linear mode increases the power to 2 x 130 watts to drive more demanding models.

Its power supply is based on a custom-designed toroidal transformer, complemented by output transformers with multi-layer windings of high-purity copper. This architecture helps maintain a wide frequency response from 5 Hz to 50 kHz.

The connectivity includes three RCA inputs, a balanced XLR input and a Pre-In input, allowing it to be used as a power amplifier. The two subwoofer outputs also facilitate the integration of one or more subwoofers into the audio system.
