Description
The new Cayin Soul 170P power amplifier is designed to deliver exceptional musicality and power. It features a Class A architecture with powerful TUNG-SOL KT170 tubes. This is also the very first time we have implemented Class A amplification in our Soul series amplifier, aiming to present a fresh and emotional take on the KT170 sound.
The Soul 170P offers both Stereo and Mono operating modes to accommodate speakers with higher power demands.
The Soul 170P features a fully integrated Dynamic Auto Bias servo circuit, allowing seamless power tube replacement without manual adjustment. This system precisely regulates the operating status of each KT170 tube, ensuring optimal matching and extending tube lifespan—all while maintaining operational safety and tube longevity.
Features:
- Silver-plated internal wiring
- Aluminum alloy anti-resonance feet
- Customized hand-wounded Toroidal power transformer and EI wide-band output transformer
- Tube soft-start circuit (60-second delay)
- MCU-controlled protection logic
- BMI indicators (to detect power tube faults and automatically engage safety mode)
