About the CAD-300SEI
The Cary Audio Design CAD-300SEI Integrated Amplifier utilizes Single-Ended Triode (SET) technology, delivering 15 watts of pure Class A power for unparalleled realism, detail, lush midrange, and dimensionality. It eliminates distortions common in other designs, creating a silent background that reveals subtle musical nuances. Praised as one of the best headphone amplifiers, it routes the full amplifier circuitry to the headphone output via a high-quality relay. Features remote volume control, three line inputs (CD, AUX1, AUX2), and is built with premium components including EI laminate transformers, 1% metal film resistors, and polypropylene capacitors. Currently on backorder until February 26, 2026, indicating ongoing production.
