For more than thirty years, conrad-johnson has refined the concept of high end audio through its relentless pursuit of excellence. The conrad-johnson Classic vacuum-tube preamplifier honors this thirty-year heritage of musically accurate preamplifiers. The Classic faithfully reproduces the harmonic structure of complex musical passages, preserving the distinctive tonal character of each instrument and voice. The space of the sound stage and the ambience of the concert hall are conveyed in realistic, three dimensional perspective. Musical transients are reproduced naturally, with realistic impact, but without the artificial enhancement which characterizes so many "hi-fi" components. Never imposing its own distractions, the Classic invites the listener to enjoy the musical performance. The phono section uses two triode amplifiers separated by a passive RIAA equalization network. The second triode amplifier is direct coupled to a high-current output stage. The Classic preamplifier is a zero-feedback circuit. It has a single triode amplifi­er direct coupled to a high-current output stage. This minimizes the output impedance, making the Classic compatible with nearly all installations. DC plate voltages are supplied by a very low impedance discrete regulator, designed to prevent the power supply from imposing its own colorations on the audio signal. Premium quality component parts are specified for the Classic to assure full realization of the potential performance of the circuit designs. Precision, metal-film resistors yield low noise performance for greatest clarity. Polypropylene and polystyrene capacitors, used exclusively in both the audio circuits and the regulated plate voltage supplies, offer maximum temporal accuracy. Phono equalization in the Classic is accomplished with 1% tolerance precision parts to assure tonal neutrality. Industrial quality controls offer extended life and maintain a crisp, precise feel.
