Redefining High-Fidelity: Krell iBias™ & XD™ – Where Power & Precision Converge
Why Krell is the Leader in hi-fi Audio Engineering
For over four decades, Krell has been synonymous with high-end audio innovation. Our commitment to pushing the boundaries of audio technology is evident in every product we create. Krell’s iBias™ and XD™ technologies are the culmination of years of research and development, designed to deliver the ultimate in sound quality, efficiency, and reliability.
Krell iBias™ Technology
Revolutionizing Class A Amplification
Krell’s iBias™ Technology is a groundbreaking innovation that redefines what is possible in high-performance audio amplification. By intelligently adjusting the power bias level in real-time, iBias™ ensures that the amplifier operates in Class A mode for the vast majority of listening, delivering the rich, musical sound that Class A is renowned for—without the excessive heat generation and energy waste traditionally associated with it.
Dynamic Biasing for Optimal Performance
Unlike conventional amplifiers, which are either biased to a fixed level or not at all, Krell’s iBias™ Technology dynamically adjusts the bias based on the demands of the audio signal. This means the amplifier provides only the amount of current necessary to reproduce the music with unparalleled accuracy. The result is an audio performance characterized by effortless dynamics, transparency, and detail, regardless of the complexity of the music.
Uncompromised Power and Efficiency
Krell’s iBias™ amplifiers offer the best of both worlds: the warmth and depth of Class A operation with the efficiency and reliability of modern amplifier design. By eliminating the heat sinks and reducing the overall power consumption, iBias™ Technology allows for a more compact, cooler-running amplifier that doesn't sacrifice power or sound quality.
Advanced Circuit Design
At the core of iBias™ Technology is Krell’s advanced circuit design, which minimizes crossover distortion—a common issue in conventional amplifier designs. The circuitry ensures that the transition between output devices is seamless, resulting in a distortion-free performance that is smooth and natural. Whether you’re listening to the subtle nuances of a jazz quartet or the full force of a symphony orchestra, iBias™ amplifiers reproduce the music exactly as the artist intended.
A New Standard in Amplification
Krell’s iBias™ Technology sets a new benchmark for high-end audio amplification. By combining Class A’s sonic benefits with innovative bias control, Krell delivers an amplifier that offers exceptional sound quality and reliability. Experience the pure, unadulterated sound of Krell’s iBias™ amplifiers and discover why they are the choice of discerning audiophiles worldwide.
Whether you’re an audiophile seeking the purest sound or simply someone who loves music, Krell amplifiers with iBias™ and XD™ technologies provide an unparalleled listening experience that brings your music to life like never before.
Krell XD™ Technology
eXtended Dynamic Range for Ultimate Control
Krell’s XD™ Technology (eXtended Dynamic) takes audio performance to the next level by significantly improving the amplifier’s control over the speaker drivers. This results in an expansive dynamic range and unmatched precision across all frequencies. XD™ reduces the output impedance of the amplifier, enhancing the damping factor and allowing for superior control of the speaker drivers. This translates into a more detailed, accurate, and emotionally engaging listening experience.
Precision and Clarity
The hallmark of Krell’s XD™ Technology is its ability to deliver precision and clarity across the entire audio spectrum. With XD™, the amplifier maintains full control over the loudspeaker, ensuring that every note, from the deepest bass to the highest treble, is reproduced with absolute accuracy. This enhanced control not only improves sound quality but also provides a more immersive and lifelike soundstage.
Immersive Sound Experience
XD™ Technology is designed to bring out the finest details in your music, creating a three-dimensional soundstage that immerses you in the performance. Whether it’s the subtle breath of a vocalist or the resonance of a cello, XD™ amplifiers reveal every nuance, delivering a truly captivating audio experience.
Seamless Integration with iBias™
When combined with Krell’s iBias™ Technology, XD™ Technology creates an amplifier that offers both unparalleled sound quality and energy efficiency. This combination allows for a listening experience that is as sustainable as it is exceptional, ensuring that every moment of your favorite music is enjoyed to its fullest potential.
