Conrad Johnson EF1

Up for sale is my CJ EF1 phono preamp.

The EF1 is a highly refined phono preamplifier designed to faithfully reproduce live musical performances, and to maintain their sonic excellence over the years.

The EF1 features low noise circuitry and selectable gain (40, 46, and 52 dB) to accommodate the full range of phono cartridges from low output moving coil to high output moving magnet types. A buffered output stage results in a low output impedance for the EF1.

First and foremost, the EF1 is an instruments for the reproduction of recorded music. The primary design objective was to create circuits which were capable of recreating the emotional impact of experiencing live music. A number of critically important considerations entered into the design process.
