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]

This circuitry protects the audio signal from voltage as if the signal is in a tunnel, providing the signal with a sheltered conduit for internal signal transmission in the current domain. At the output stage, CAST technology provides the most accurate signal transfer from one component to the next. As a stereo preamplifier, the KCT delivers state-of-the-art music reproduction to either of two in...[more]

Building on our thirty year tradition of designing electronics of the highest quality and value, Audio Research is pleased and very excited to introduce the LS12 stereo preamplifier, which bridges the usual gulf between solid-state and vacuum-tube sound, sonically outperforming the competition anywhere near its retail price.   The LS12 represents a major advance in solid-state circuit design ...[more]

The crossover functionality offers the ability to use a subwoofer/satellite speaker arrangement and still maintain the highest quality sonic performance. Previous to the Phantom preamplifier, this system configuration would require signals to pass through a subwoofer's lower quality crossover circuitry. The Phantom preamplifier is the centerpiece of a world class audio system where space is at ...[more]

Sharing the same audio circuitry as its bigger brother, the Phantom II 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 desig...[more]

Circuitry Highlights The Phantom 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 feed...[more]

Concept The Reference Series from Audio Research was first introduced in 1995 and has been the ultimate representation of performance, musicality and power. Beginning with the Reference 1, the Reference 6 now continues the tradition of using the most refined circuit designs in concert with the highest quality parts and components. Numerous elements – transformers, capacitors...[more]

Constellation Virgo II now includes the same power supply used for Altair. This supply offers numerous advantages. While the original Virgo’s power supply took electrical isolation to a high level with separate transformers and outputs for the audio and control circuits, the Constellation Virgo II supply enables true dual-mono operation, with separate transformers and outputs for left-cha...[more]

The core of the Virgo is Constellation Audio’s Line Stage Gain Module, a fully balanced preamplifier circuit that achieves essentially perfect balance between the positive and negative halves of the audio signal. The musicality and transparency of this circuit are unequalled in any other preamp available. The Line Stage Gain Module also makes possible the Constellation Link, a direct conn...[more]
