While the video capabilities of this piece are outdated, the Showcase is still an an amazing audio processor for both your 7.1 and two channel audio requirements.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

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 display.

Fully tested in our lab and working as it should. A few light scratches on the case but nothing very serious.  

Includes the preamp and a power cord.

From a review:

"After using the Showcase Processor for a couple of weeks, I felt that I had found a cure to my personal Upgradeitis affliction; it is that good... The depth of the soundstage and clarity of the presentation create a sense of immersion in movies and music that every person who loves great sound longs for. The Showcase Processor is very flexible, stays on the cutting edge of technology with features like digital room equalization, and sounds simply wonderful."

The Showcase Processor is THX Ultra certified and features THX Surround EX, Dolby Digital 5.1, Dolby Digital EX, DTS-ES 6.1, DTS NEO:6, and Dolby Pro Logic II processing, in addition to nine proprietary Krell Music Surround modes. This flexibility allows upgrades to software via Flash memory for future surround sound formats and design enhancements.

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.
