Cayin HA-3A
A transformer-coupled, balanced vacuum tube headphone amplifier designed for both performance and style. Featuring 4-Pin XLR, 4.4 mm, and 6.35 mm outputs in a compact A4-sized chassis, it offers selectable Low, Mid, and High impedance for optimal headphone matching.
Premium Tube Design
Uses hand-matched Electro-Harmonix 6V6EH GT driver tubes and RCA 25AX4GT rectifier tubes, delivering pure, natural sound through a single-ended vacuum tube circuit with transformer-coupled outputs.
Precision Engineering
Custom-wound output transformers ensure powerful, low-noise performance. Balanced outputs have separate left/right grounds for improved stereo separation, while point-to-point gold-plated wiring preserves signal integrity.
High-Quality Components
Equipped with an ALPS volume potentiometer, stainless-steel and aluminium construction, large anti-vibration foot pads, and comprehensive circuit protection with a 60-second start-up delay.
