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]

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]

Like the DAC8, the DSPre offers the following:• Five digital inputs, including USB 2.0HS, AES/EBU, RCA, BNC, andToslink®, all of which are capable of decoding 24 bit/192k files.• Asynchronous USB.• Utilizes quad “monoblock DAC” architecture with dual low jitter mastercrystal oscillators to eliminate decoding and quantization errors, increasethe dynamic range, and ...[more]

Often overlooked, the preamplifier is a critical component in the signal chain. A small signal must be carefully amplified without damaging the ephemeral staging and dimensional components of the music. The Evolution 202, using a combination of advanced technologies and inspired design, elevates this task to an art form. Music emanates from an expanse that outlines the recording venue, transpor...[more]

The Evolution 222 brings the advanced technologies and inspired design of the Evolution 202 to single chassis format. Often overlooked, the preamplifier is a critical component in the signal chain. A small signal must be carefully amplified without damaging the ephemeral staging and dimensional components of the music. Heard through the Evolution 202, music emanates from an expanse that outline...[more]
