Versatile preamp from Classe that's an excellent match to our newly listed (and high-powered) Classe CP-200 Amplifier.

Sold for $2,700 back in 1997, which equals about $4,350 in today's dollars.

Featuring a clean front panel with nicely laid out and easy to access controls, along with a real and solid-feeling volume control knob. 

Offering two sets of Balanced XLR inputs which is very handy for high-end sources, along with a host of single-ended RCA inputs.

Also features both XLR and RCA outputs to feed your amplifier via the best method possible.

*Classe offered an optional phono section for this model to connect your turntable, which is not installed or included with this preamp.

The SkyFi Testing Process for Preamplifiers:
We start with a visual inspection of all internal components to make sure there are no signs of stress or aging. Capacitors are checked for telltale sings of bulging or leaking, resistors are checked for signs of overheating or cracking, and transistors are checked for signs of stress or damage. Special attention is paid to the power supply which is the most common source of failure for preamps. We then power up the unit and run a simple 1k sine wave while monitoring the low voltage output on an oscilloscope for signs of distortion or noise to get a baseline.

At this point we will lubricate and clean all switches and potentiometers (that are not sealed) with a high quality contact cleaner, and then re-test all functions for any signs of noise or scratching.

Final testing involves putting actual music through the preamplifier We have learned over time that some issues are only noticeable to a trained ear while listening to a familiar source material. Our test bench has reference vintage KEF speakers that we are super familiar with which will quickly reveal any discrepancies. Some preamps will then move into the listening room where they will be tested with our in-house reference system.
