The Sansui CA-2000 is a stereo control amplifier introduced in 1975, which showcases the evolution of Sansui's audio technology. It features an elegant black and silver design that distinguishes it from other offerings of the time. The internal circuitry utilizes a 7-chip configuration with a differential input and a pure complementary service class A push-pull design for the final stage amplifier. A focus on low noise is achieved through the selection of high-quality transistors, enhancing stable operation over a broad frequency range. The RIAA deviation is finely tuned to maintain a flat characteristic, employing precision components such as metal film resistors and styrene capacitors. The CA-2000 allows for extensive control over sound through various tone adjustments, employing a triple tone control system that facilitates independent adjustments for midrange, bass, and treble, along with turnover frequency settings for granular sound shaping. Additional features include a low and high-frequency filter, dual tape deck capability, and headphone amplification. Build quality is exemplary, and the unit incorporates a powerful transformer and stable power supply circuitry to ensure performance consistency. The amplifier offers 1V preamplifier output and can handle various input sensitivities across its phono and auxiliary inputs. Over the years, the CA-2000 has garnered a strong following among audio enthusiasts, appreciated for its rich, warm sound and exceptional functionality.
