Complete set from Krell looking and working like the day it left the factory. In fact, the owner reports that it has had very little use and it sure shows that way. 

While it's not included, it has the ability to accept a digital processor card which you can order from Krell if you'd like to have a single-box solution.

It even includes a headphone jack - the first we've seen on a Krell preamp!

Includes everything, remote, printed manual, cables and all original packaging.

Tested in our lab where it met all factory specifications. The display is bright and clear, and there are no signs of use or handling anywhere on the chassis.

$5000 MSRP.

Features Same Engineering Language as Krell's Flagship Preamp

The Phantom III is the first Krell preamplifier to include either an optional digital input module or a headphone output. The digital module features AES/EBU, coaxial, and optical digital inputs for use with streaming devices or other digital sources.

The Phantom III is the perfect centerpiece for a world class digital and analog audio system.

**Circuitry Highlights**
The Phantom preamplifier is a dual monaural design with the left and right channels afforded their own power supply regulation and individual circuit boards. All signal gain is executed with surface mount technology using proprietary multiple-output current mirrors with nearly 500 times the open loop linearity of other designs. Featuring 700 kHz bandwidth in a zero feedback, balanced, Krell Current Mode design, the Phantom III shares the same design philosophy as its bigger brother, the flagship Phantom preamplifier. Negative feedback is not used anywhere in the preamp, nor is it necessary. Open-loop distortion is typically less than 0.003%. The volume control is realized with a balanced resistor ladder - bandwidth and transient response of the preamp circuitry are virtually unaffected by the volume setting. The headphone circuitry is identical to the main circuitry, offering private listening with the same performance as speaker playback.

**Digital Module Highlights**
The digital module supports up to 24 bit/192kHz LPCM. All digital signals are fed to an ESS Sabre DAC and then sent to Krell's Current Mode, discrete, balanced analog circuitry. Being a modular design, the optional digital converter module is easily added at any time.

**Power Supply Highlights**
Oversized for a preamplifier, the power supply features a 95 VA transformer and 40,000 µF of capacitance giving it the ability to respond quickly to musical demands. The large power supply improves noise rejection and renders the Phantom III impervious to all but the most severe AC voltage power fluctuations. A new eco-friendly standby mode reduces power consumption to 2W
The Phantom III preamplifier is available in silver or black finish.

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.
