Krell Announces Its New Illusion Preamplifiers

Alexander Lamascus

Those familiar with Krell’s penchant for pushing the limits of hi-fi audio technology will not be disappointed with the new Krell Industries Illusion ($15,000) and Illusion II ($7,000) preamplifiers. Consistent with past preamplifier models by Krell, the Illusion preamp separates the power supply from the audio circuitry to ensure playback that is uninhibited by the interference associated with noisy, vibration-inducing power transformers. The Illusion also employs a high-end crossover circuit, allowing the user to limit the amount of audio signal sent to a subwoofer down to the necessary frequencies, rather than relying on the subwoofer’s circuitry to process the entire frequency range. A dual-monaural circuit design affords additional sonic purity, processing the signal for each channel separately to ensure minimum interference between them. No negative feedback is needed with the preamps to account for gain stages, allowing listeners to enjoy the immense power and precision of their system at its highest sonic fidelity. For the audiophile moving to the digital world, the Illusion II model integrates the power supply within its housing and adds five digital inputs, enabling connection to streaming hubs, music servers, and other digital music sources. These inputs send audio signals through the onboard ESS Sabre digital-to-analog converter and support file resolutions up to 24 bits/192 kHz. Both Illusion models will be available at the end of the month. (www.krellonline.com)
