Krell Industries, Inc, is the premiere manufacturer of high-end audio equipment, featuring award winning amplifiers, preamplifiers, SACD players, DVD players, surround sound processors, digital-to-analog converters, and loudspeakers for serious music lovers and home theater aficionados. Krell consistently has garnered laudatory reviews and won wide ranging praise from the industry's most knowledgeable and discerning commentators and reviewers. Perhaps no company in audio today enjoys a more distinguished reputation for engineering innovation and product excellence than does Krell Industries, Inc.
The S-300i integrated amplifier combines a fully balanced, Class A preamplifier circuit with a stereo amplifier rated at 150 watts per channel into 8 ohms and 300 watts per channel into 4 ohms. Its circuit design borrows the Current Mode technology used in Krell's top-of-the-line Evolution amps and preamps. This technology delivers unequaled signal bandwidth, ensuring clear, powerful response from the deepest notes of the bass drum to the highest notes of the piccolo. A massive toroidal transformer makes the S-300i's amplifier section one of the most robust ever incorporated into an integrated amplifier.

Krell Phantom preamp
With the Phantom Preamplifier, musicians appear silhouetted by the air about them, filling the room with a mesmerizing depiction of the recording. Music emanates from an expanse that outlines the recording venue, transporting you to the moment of creation. Coupling advanced technologies and inspired design, the Phantom preamplifier elevates preamplifier performance to an art form. The Phantom preamplifier is the first Krell preamplifier to include an optional crossover. The crossover functionality offers the ability to use a subwoofer/satellite speaker arrangement and still maintain the highest quality sonic performance. Previous to the Phantom preamplifier, this system configuration would require signals to pass through a subwoofer's lower quality crossover circuitry. The Phantom preamplifier is the centerpiece of a world class audio system where space is at a premium.
Krell S-350a CD player
The S-350a CD player establishes a new high standard of performance and value among high-end compact disc players. Incorporating an advanced TEAC slot load disc transport mechanism, premium digital circuitry, Class A analog circuitry, Krell designed anti-jitter master clock, and sophisticated high-linearity power supply, the S-350a delivers performance unequaled by many more expensive players. It is the ideal CD player for the serious music lover. A coaxial and toslink digital input extends the S-350cd's digital to analog conversion circuitry to two additional audio sources. The S-350a complements the S-300i integrated amplifier both in industrial design and sonic performance, a treat for the eyes and a feast for the ears.

The Evolution e Series continues to expand, and now offers seven powerful amplifier models. Stereo components include the flagship Evolution One, the new Evolution 302, and the Evolution 402 amplifier. The Evolution 403 is a three-channel amplifier and the Evolution 400, 600, and 900 are monaural amplifiers. Two monaural amplifiers are required for stereo operation. The Evolution 400 Monaural Amplifier has a compact chassis containing all the high power, wide bandwidth, and low noise characteristics designed into every Evolution Series amplifier. Each Evolution amplifier enjoys the hereditary advantage first inherent in the Evolution One amplifier, from faceplate to binding posts.
Realized in monaural, stereo, and three-channel configurations, Krell Evolution amplifiers bring the en-gaging reproduction of music and movie soundtracks debuted in the flagship Evolution One to a potent new platform. With virtually unlimited power available, delivered through the most refined circuitry yet conceived, Evolution amplifiers strike the fine balance between pure visceral response and delicate articulation
Active Cascode Topology eliminates global negative feedback, only nested local feedback is employed around individual gain blocks. The result is an extraordinarily open, liquid, effortless sound. The signal path incorporates Krell Current Mode and CAST circuitry using proprietary multiple-output current mirrors in a complementary and balanced arrangement for extraordinary open loop linearity. Evolution circuit topology breaks through bandwidth limitations of conventional designs resulting in near perfect performance in the audible range. A complete Evolution (source, preamplifier, amplifier) system, connected in CAST, reduces the number of voltage gain stages to the minimum, one. The resulting noise floor is approaching the theoretical limit of technology. All Evolution amplifiers feature massive power supplies with the Evolution 402 and Evolution 600 equipped with a 5000 VA power supply and the Evolution 403 and Evolution 900 housing 6000 VA power supplies. The power supply makes use of extensive electrical and magnetic shielding to keep radiated interference out of critical amplifier circuits. Internal high current line conditioning circuitry filters RF noise on the AC mains, as well as compensating for asymmetric power waveforms and DC on the mains. The rails powering the amplifiers' low level and gain stages are regulated twice for total immunity from fluctuations in the AC mains and virtually noise-free output. Advanced microprocessor control monitors critical operational parameters. Bias, load impedance, regulator output voltages and operating temperature are all continuously monitored.

Krell Phantom III 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 and supports up to 24 bit/192kHz LPCM
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.
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. Available in silver or black finish.
