Cayin HA-3A Headphone Amplifier
The Cayin HA-3A is a meticulously crafted vacuum tube headphone amplifier that combines exquisite design with first-class engineering. This compact yet powerful amplifier is designed to provide an engaging and immersive audio experience, allowing you to enjoy your music through a variety of headphones or earphones.
The HA-3A offers versatile headphone output options, including single-ended and balanced outputs, and features three levels of headphone impedance settings to ensure optimal performance for different headphone types. Its dual input ports support both balanced (XLR) and single-ended (RCA) connections, providing flexibility in source selection.
Built with craftsmanship and precision, the HA-3A features a hand-made construction with point-to-point wiring, ensuring the shortest signal path and better attention to detail. The amplifier’s chassis and transformer pots undergo a 14-round crafting process to achieve a refined and delicate texture, protecting the amplifier over years of use.
The HA-3A uses carefully selected and hand-matched vacuum tubes to deliver clean, high-quality sound. Its RCA 25AX4GT rectifier tube ensures minimal interference and provides clean power to the amplification circuit. Additionally, the high-quality ALPS volume control offers precise and smooth volume adjustments.
The Cayin HA-3A represents a pinnacle of audio craftsmanship, designed to deliver a dedicated, engaging, and indulgent listening retreat for audiophiles.
