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.
