A preamp of this design, sophistication, and parts quality would cost close to $5k just to MAKE today.

An aluminum chassis, high quality PCB's, and selective high tolerance components are just a few of the nice touches you'll find upon closer inspection.

Some of its great features include:

Selectable MC and MM phono input, Defeatable tone controls, Rumble filter for the turntable, Rosewood side panels (originally optional and currently fetching over $300 alone), Loudness feature for low level listening, High quality headphone amplifier section with volume control, Convenience power outlets.

Our Testing Process for Preamplifiers (All) at SkyFi:

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.
