Conrad-Johnson also offers a Special Edition of the Classic preamplifier, the Classic SE. The controls, features, and basic circuitry remain the same, but the sonics benefit from strategic parts upgrades. Specifically, series resistors in the line stage are replaced with Vishay metal-foil resistors, and polypropylene by- pass capacitors (on the output coupling capacitors and regulated power supply capacitors) are replaced with CJD Teflon capacitors. The Classic SE phono stage gets similar parts upgrades to the line stage circuit. The sonic performance improvement is immediately noticeable as higher resolution, finer gradations in dynamics, purer transients, and increased weight and body in the sound. It all adds up to a very nice improvement, making the Classic SE a near state of the art contender at the very modest pricing of $2650 for the linestage and $3500 with phono. Owners of the standard versions can also have the upgrades performed on their units.

The Classic SE preamplifier is available as either a line-stage, or with an optional phono stage. Both stages are zero-feedback circuits. 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 line-level section has a single triode amplifi­er also direct coupled to a high-current output stage. These output buffer stages minimize 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 is accomplished with 1% tolerance precision parts to assure tonal neutrality. Industrial quality controls offer extended life and maintain a crisp, precise feel.
