Sansui CA-3000


The Sansui CA-3000 is a stereo control preamplifier featuring advanced space-age design in every link of the circuit chain, for unprecedented accuracy.

It has RIAA ± 0.2dB Equalisation which is capable of meeting all the strenuous demands of contemporary disc recordings which feature extremely wide dynamic range.

The CA3000 handles an extremely wide frequency response covering all musical signals with low distortion, no clipping or noise.

Features include:

High input impedance and low output impedance, through newly-developed unit amplifier circuits: a differential amplifier at input, and an emitter-follower or SEPP buffer amplifier at output.

Phono equaliser features a packed differential dual FET amplifier (with a matched pair of low-noise FET's) at the initial stage, and Class-A complementary SEPP amp at output.

Full controls and connections for any combination you're likely to need.
