conrad-johnson Classic 2 Vacuum-Tube Line Stage Preamplifier
The new conrad-johnson Classic 2 now features the same tube found in the more expensive ET3. For more than 30 years, conrad-johnson has refined the concept of high end audio through its relentless pursuit of excellence. The Classic 2 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 Classic 2 preamplifier is a zero-feedback circuit. It has a single triode amplifiÂer direct coupled to a high-current output stage. This minimizes the output impedance, making the Classic compatible with nearly all installations, including those requiring long lengths of interconnect cable. 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. A regulated filament supply further isolates the unit from ac line voltage fluctuations. Premium quality component parts are specified for the Classic to assure full realization of the potential performance of the circuit designs and to dependably sustain that performance for years to come. 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 2 is accomplished with 1% tolerance precision parts to assure tonal neutrality. Industrial quality controls offer extended life and maintain a crisp, precise feel.
