Krell KRC-2 Analog Preamplifier from Krell's Golden Era

Free Shipping on *ALL* Electronics (Excluding Speakers, Contiguous 48 US States Only)

One of our favorite preamps from Krell. Very transparent and almost undetectable in the signal path.

And it's built like a tank using the best parts quality available at the time.

You would have to *easily* spend about $6k today to find a better and current preamp.

Serviced and tested in our shop lab and listening room and working perfectly.

Krell KRC-2 Preamplifier - Manual

From a vintage Stereophile review by Martin Colloms:

I found the KRC-2 to be a well-balanced performer: neutral, reliable, satisfying, and capable of inspiring confidence.

Musically, it approaches the Class A performance of the KRC; it can therefore be included in that handful of state-of-the-art preamplifiers costing between $5000 and $10,000.

And, as one of the least expensive designs in this group, it is an easy recommendation.

Don't expect the KRC-2 to grab you by the throat; rather, settle back and let its soundly balanced performance convince you that sonic fireworks are unnecessary for long-term owner satisfaction.

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.
