The Cary Audio Design CPA-1 is a stereo preamplifier designed for audiophiles seeking high fidelity and musical accuracy. It features a tube-based phono stage with multiple gain settings (high, medium, low) and a solid-state output stage, combining the warmth of tubes with the reliability of solid-state technology. The unit offers a frequency response of 5 Hz to 100 kHz within ±0.1 dB, a signal-to-noise ratio of 120 dB (line), and extremely low total harmonic distortion (THD) of 0.001%. It includes multiple balanced XLR and single-ended RCA inputs and outputs, with a gain of approximately 26.8 dB. The CPA-1 requires a break-in period of about 100 hours for optimal sound quality. Dimensions are approximately 4.5" H x 17" W x 13" D, and it weighs about 22-23 lbs. It is praised for its transparent, spacious sound staging and musicality, making it a respected choice in the high-end preamplifier market. The CPA-1 is no longer in production but remains sought after by enthusiasts.
