(SECTION ONE: About Krell continued)

From the KSA–100 to the present, Krell C.E.O. Dan D’Agostino has continually “pushed the envelope” of performance in his search for greater amplifier power. His exploration of new technologies, driven by his never-ending quest to elevate the standard of excellence, has resulted in breakthrough audio designs. Over the years, the Krell line of power amplifiers, including benchmark products such as the KRS–100, KRS–200, and the Audio Standard models, has established a legacy of unparalleled sonic performance.

The Krell product line has diversified, but Dan’s fundamental research into amplifier design and performance remains at the core of the company’s achievements. Every Krell component upholds the legacy, incorporating unique technologies that are the direct result of Dan’s discoveries in audio amplification.

The Evolution One amplifiers build on the Krell legacy. They provide unprecedent- ed linearity with the control and accuracy that only comes from superior current capability. The sound is lively and unconstrained, in a manner that evokes live per- formance and the true sound of instruments.

Dan D’Agostino remains committed to the development of new designs and technologies. And the Krell legacy will continue to evolve with products that deliver innovative engineering, perfection in build quality, and outstanding audio performance.

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.
