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.

The Kleos is the lowest cost Lyra cartridge to feature the full fledged Ogura manufactured boron cantilever and coil system with Lyra original line-contact (3 x 70μm) stylus. This is similar to what is employed on even the most expensive Lyra models. The most important element of the new Kleos is it's sound. We firmly believe that the Kleos is capable of extracting more information from the vinyl grooves than it's predecessors, and that the reproduction of music is both more dynamic, more detailed, and more natural than the models preceding it. We also are of the opinion that the Kleos will set a new standard for sonic performance at it's price point. Today there are only a small handful of master cartridge builders in the world, and Lyra's Yoshinori Mishima belongs to this elite group of individuals that are capable of crafting the highest level MC transducers on the planet. His assistant Akiko Ishiyama, who has undergone several years of apprenticeship, is also involved in the building process leading to each Kleos. The Kleos is not only hand made, but each cartridge is listened to extensively and "voiced" by the master cartridge builder, like the finest musical instruments. Lyra offers a unique combination of capable, advanced cartridge design by Jonathan Carr and complete handmade execution by the above mentioned individuals. Investing in a Lyra Kleos through an authorized retailer will offer you an unparallelled analog experience from your stereo microgroove vinyl records
