Five Vintage NOS Vacuum Tubes
At the heart of the system are five New Old Stock (NOS) vacuum tubes, selected for their superior sonic fingerprints. These vintage components provide a level of rich detail and an expansive soundstage that modern equivalents struggle to match. The result is a signature sound defined by exquisite musicality and that sought-after "classic warmth."
Single-Ended Class A Amplification
To truly honor the vintage hardware, the amplifier utilizes a Single-Ended Class A circuit. This design is intentionally purist, ensuring the unique tonal characteristics of each NOS tube are fully harnessed without interference. It provides a direct, transparent path for your music, resulting in a pure and emotionally engaging performance.
Balanced and Mellow Tonal Character
The internal architecture and bespoke wiring are meticulously engineered to preserve a specific acoustic profile. By focusing on rich harmonic qualities, the design ensures a balanced and mellow output. This prevents listener fatigue while maintaining the lush, "tubey" texture that audiophiles prize.
Advanced Power and Output Engineering
Consistency is guaranteed by a sophisticated multi-stage filtering system and a low-noise FET voltage regulator. To ensure your headphones are driven with absolute precision, the unit features Cayin’s proprietary Z11 core EI output transformer. This in-house development allows the amplifier to handle various headphone loads with ease, maintaining clarity and grip across the entire frequency range.
