The Soul 170C is the newest vacuum tube preamplifier from Cayin, built on more than 30 years of tube engineering experience. Crafted for outstanding musical performance and accuracy, this 2-channel preamp delivers excellent channel separation and remarkably clean signal transmission.

As part of Cayin's distinguished Soul Series, the Soul 170C carries forward the signature design philosophy of the lineup. Its bold profile and refined craftsmanship reflect the cohesive styling shared across the Soul family, creating not only sonic synergy but also visual harmony—perfectly complementing the Soul 170P power amplifier.

Tube Configuration

The Soul 170C is built around a precisely matched set of vacuum tubes, including:

2 × ECC83
2 × 6SN7GTB
2 × 6CA7
2 × 17AX4GT

For a clean and stable DC supply, the unit utilizes a full-wave rectification design centered on the 17AX4GT rectifier tube, known for its efficiency and low internal resistance.

Voltage regulation is handled by 6CA7 tubes, delivering steady and independent power to each channel for optimal performance.

For line-stage amplification, the Soul 170C incorporates high-gain, high-linearity ECC83 and 6SN7GTB tubes. This carefully selected pairing ensures precise signal amplification with minimal distortion, preserving the clarity and musical essence of the source material.

Adjustable Negative Feedback (NFB)

To refine the tonal character of your system, the Soul 170C integrates a precisely engineered Negative Feedback (NFB) circuit. This feature plays a crucial role in shaping how the preamplifier controls and influences the downstream power amplifier.

Within the Soul 170C, the NFB circuit enhances signal linearity, lowers harmonic distortion, and contributes to the overall sonic texture delivered to the next stage.

Users can select between two NFB modes—High and Low—allowing for tailored tonal balance depending on system matching and personal listening preference.

Low NFB: Produces a more spacious, natural, and emotionally expressive sound presentation—ideal for systems that benefit from greater openness and musical flow.
High NFB: Improves clarity, precision, and control—suited for listeners seeking tighter bass response and a more analytical sound profile.

Remote Control Convenience

An included infrared remote control provides effortless access to all key functions, including input selection, NFB adjustment, and volume control. This allows for smooth, convenient system management from your listening position.

Connectivity Options

Inputs: 4 × RCA pairs, 1 × XLR pair
Outputs: 1 × RCA pair, 1 × XLR pair

With both single-ended and balanced connections available, the Soul 170C integrates easily into a wide range of audio system configurations.

Premium Components & Internal Construction

Hand-assembled using meticulous point-to-point wiring, the Soul 170C is designed to minimize signal degradation and channel interference. Notable internal components include:

Silver-plated internal wiring
Premium-grade coupling capacitors
ALPS motorized volume potentiometer
Proprietary in-house designed, hand-wound power transformer

Protection & Reliability

To safeguard internal components and extend operational lifespan, the Soul 170C includes:

A soft-start circuit with approximately 60-second warm-up
A removable tube protection cover for added safety

These features ensure dependable performance and long-term durability.

Chassis & Aesthetic Design

Solid anodized aluminum front panel
Hand-finished North American black walnut side panels

Blending advanced engineering with refined craftsmanship, the Soul 170C is both a high-performance audio component and an elegant visual statement—designed to stand proudly at the center of any premium hi-fi system.
