The Krell Legacy

“I design every Krell component to set the standard

for workmanship, style, and performance.”

Dan D’Agostino

High-end audio is a demanding pursuit—an ongoing quest for excellence in music reproduction that drives equipment manufacturers to strive for the absolute in design and performance. With a keen understanding of this passionate drive, Krell Industries, Inc., was founded in 1980.

Over the past 2-1/2 decades, Krell has earned a distinguished reputation for engi- neering innovation and product excellence. The company’s history is replete with product introductions that have deeply impacted the high-end audio industry. The most discriminating audiophiles and product reviewers have consistently recognized Krell components for standard-setting performance.

The Evolution One amplifier brings Krell design to a new level, setting a standard for performance that will not soon be matched. The shear breadth of this amplifier’s dynamic range capabilities conveys a startling realism that transcends previous designs. Seemingly unlimited frequency response, combined with unerring accu- racy and fortitude, extend a tradition that began with the first Krell amplifier — the KSA-100.

The KSA–100 was the first high-power, high-current, true Class A biased stereo power amplifier available to audiophiles. It was the first Krell product, and its resounding success established Krell as an important new technological contrib- utor to high-end audio.

Evolution One specifications

Krell Industries is synonymous with high-fidelity audio and innovative engineering, showcasing their prowess in speaker design with the Evolution One. This speaker embodies the cutting-edge technology and striking aesthetics that Krell is recognized for in the audiophile community.

The Evolution One features a unique dual-woofer configuration, delivering powerful bass response without distortion. Each woofer is meticulously crafted from advanced composite materials, ensuring that the sound remains accurate and dynamic, even at high volumes. This design aligns perfectly with Krell's dedication to reproducing music with the utmost authenticity.

At the heart of the Evolution One is Krell's proprietary CAST (Current Mode Amplification) technology. This innovation sets Krell apart from competitors by allowing the signal to flow through a path that maintains the purity of the audio signal. By operating in current mode rather than voltage mode, CAST drastically reduces the impact of circuit interference that often plagues traditional audio systems. The result is a level of transparency and low distortion that appeals to even the most discerning audiophiles.

The speaker also incorporates advanced crossover technology, which seamlessly integrates the woofers and tweeter. Krell employs a fourth-order Linkwitz-Riley crossover to ensure that the different drivers work in perfect harmony. This feature aids in achieving a balanced and cohesive soundstage, enhancing the listening experience across various musical genres.

Visually, the Evolution One is a statement piece. Its sleek, modern design is complemented by a high-gloss finish, ensuring it not only sounds exceptional but also serves as an elegant addition to any audio setup. The robust cabinet construction eliminates unwanted vibrations, further enhancing sound clarity.

Moreover, the Evolution One is equipped with advanced bi-wiring and bi-amping options, allowing audiophiles to optimize their setups based on personal preferences and system requirements. This flexibility makes the Evolution One an adaptable choice for those looking to refine their audio systems further.

In summary, the Krell Industries Evolution One is a culmination of innovative technology, premium materials, and exquisite design. With features such as dual-woofer configurations, CAST technology, and advanced crossover design, it stands as a testament to Krell's commitment to delivering high-fidelity audio experiences that resonate with both casual listeners and dedicated audiophiles alike.
