Cayin Soul 170HA | Flagship Class A Speaker/Headphone Tube Amplifier

Experience the Soul of Music

Immerse yourself in the sumptuous sonic feast of the Cayin Soul 170HA, a flagship single-ended Class A tube amplifier engineered for both headphones and speakers. With the world’s first use of Tung-Sol KT170 tubes in a Class A single-ended architecture, it delivers a masterful combination of power, purity, and musical emotion. Producing up to 18W per channel for speakers and 18W max headphone output via XLR, the Soul 170HA provides a rich, lifelike performance that truly captures the essence of your music.

Pure Single-Ended Voltage Amplification

Driven by dual 6SN7 tubes in the voltage stage and matched KT170 output tubes, the Soul 170HA achieves exceptional linearity and tonal depth. The amplifier’s single-ended Class A design ensures a continuous, distortion-free signal path, preserving micro-details and dynamic contrast for a deeply immersive listening experience.

Outboard Power Supply for Pristine Clarity

The dual-chassis design separates the power supply from the main amplifier for ultra-low noise and enhanced clarity.

• Dual Power Transformers: Independently handle high and low voltages for minimal interference.

• Tube-Regulated Circuit: JJ GZ34S rectifier tubes provide clean, stable DC power for every amplification stage.

• Heavy-Duty Umbilical Cable: Custom silver-plated 6N copper cable ensures lossless current delivery and long-term reliability.

Triode & Ultralinear Dual Operation Modes

Tailor your sound with two distinct tube operating modes:

• Triode Mode: Smooth, warm, and emotionally rich—ideal for vocals, jazz, and acoustic performances.

• Ultralinear Mode: Dynamic, open, and powerful—perfect for orchestral, rock, and cinematic music.

Impedance-Matched Headphone Output

Featuring three selectable impedance levels—Low (8–64Ω), Mid (65–250Ω), and High (251–600Ω)—the Soul 170HA offers optimal performance with any headphone type, from sensitive IEMs to demanding planar magnetics. With 6.3mm, 4.4mm balanced, and 4-pin XLR outputs, it ensures perfect pairing across your collection.

Precision Volume Control

A custom ALPS potentiometer works with dual JRC MUSES72320V volume chips, delivering 128 steps of precise, channel-balanced control with a 0dB gain difference between left and right channels—ensuring exact stereo imaging and effortless volume adjustment.

Craftsmanship & Aesthetics

Encased in aerospace-grade aluminum with North American black walnut side panels, the Soul 170HA exudes elegance and authority. The VU meters glow warmly as the tubes breathe life into your sound, while the protective tube cage adds both safety and theatrical flair to its commanding presence.
