Krell Audio + Video Standard Preamp/Processor - A Well Kept Audio Secret

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

Original MSRP was around $14k.

Please check out our video review for the full details on this pre/pro:

There are no scratches or really any signs of use, and the display is bright and clear.  

While the video capabilities of this piece are outdated, the Audio + Video Standard is still an an amazing audio processor for both your 7.1 and two channel audio requirements.

Just look at our photos to see the complement of balanced XLR + RCA inputs and outputs!  Including 5 total digital inputs, one of which is a (XLR) AES/EBU professional type digital input.

It even has a very capable DAC built in - likely better than the one in your CD player. 

It also has a preamp button that instantly turns this unit into a high-quality two channel preamp, bypassing all the unnecessary bits.

It's housed in a super well built all-aluminum chassis with a brightly lit Krell "RED" style display.

Fully tested in our lab and working as it should.

Includes the power cord (no remote is included).

Our Testing Process for Preamplifiers 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.
