The Krell Illusion preamplifier is a dual monaural circuit design with the left and right channels afforded their own power supply regulation and individual full chassis sized boards. All signal gain is realized in surface mount topology using proprietary multiple-output current mirrors with nearly 500 times the open loop linearity of other designs. 1.5 MHz open loop bandwidth in a zero feedbac...[more]

Circuitry Highlights: the Illusion II 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 fee...[more]

The Line Stage Gain Module employs fully balanced, mirror-imaged circuits made with hand-matched, ultra-low-noise transistors. A unique servo circuit monitors the signal balance and corrects for even minute inconsistencies. If you use a Constellation Audio amplifier, you can feed the Inspiration 2 Preamp’s output to the amp’s Constellation Switched-Mode Power Supply (C-SMPS) pro...[more]

The improvements in the LS28SE stem from what was learned during the creation of Audio Research’s Reference 160-series amplifiers. Very similar to the wire and parts changes incorporated in the REF6SE and REF PH3SE, the LS28SE also includes upgrading to the same proprietary gold coupling caps used in the REF6SE. These numerous and costly component upgrades elevate the LS28SE’s perfo...[more]

Constellation Audio, the renowned luxury goods manufacturer of high performance solid-state electronics, is pleased to announce the introduction of the new Revelation Series of components at CES 2017. CEO Dr. Murali Murugasu challenged his dream team of designers and engineers to develop a new series of Constellation Audio components that could deliver the essence of our renowned Performance Se...[more]

We like to say the Inspiration PREAMP 1.0 is distilled, not diluted. It embodies the essence of our earlier work while retaining the subjective musicality and objective performance that won so much acclaim for our previous preamps. The most vital technology in our preamps is the Line Stage Gain Module, a fully balanced amplification circuit that uses servos to maintain a pristine balance be...[more]

Power Supply Highlights Positioned between the two audio channels, the power supply makes use of extensive electrical and magnetic shielding to keep radiated interference out of critical preamplifier circuits. Internal line conditioning circuitry filters RF noise on the AC power and compensates for asymmetric power waveforms and DC on the mains. Power for the preamplifier stages comes from ...[more]

The Line Stage Gain Module is a big part of why Constellation components have won raves from so many reviewers over the last decade. The module incorporates fully balanced, mirror-imaged circuits made from hand-matched, low-noise transistors. A unique servo circuit monitors the signal balance and corrects for any inconsistencies. Owners of Constellation amplifiers can feed the ...[more]

The Virgo III is an evolutionary step from the former Virgo II and like its predecessor the new Virgo III uses a separate power supply for better isolation and lower noise. Compared to its predecessor, the Virgo III will provide improved remote control operation, smoother operation of front panel knobs, and new internal circuitry that allows a quicker warmup time for virtually instantaneous pea...[more]
