Power to Drive Almost Any Speaker and Full, Sweet, Warm Tube Sound That Makes Music Sing: Bob Carver Crimson 275 Stereo Amplifier Also Features Incredible Warranty

There's nothing like the sound of tubes – a fact iconic audio designer Bob Caver knows as well as anyone. Responsible for some of the most revered valve designs in the history of high-end audio, Carver marries beautiful, sweet-sounding tube performance with stop-you-in-your-tracks value in the Crimson 275 Stereo amplifier. Inspired by its Crimson 350 sibling and hand-built in the U.S.A., this gorgeous powerhouse is fueled by the same Tung-Sol KT120 tubes as Carver's monoblock amps. It plays with a richness, fullness, warmth, and boldness that takes you to the edge of the studio (or concert) stage.

Nominally rated at 75Wpc, Crimson 275 Stereo actually delivers 100RMS/channel into four ohms – enough power to let you hear (and feel) your music. A DC restorer circuit, exclusive to Bob Carver designs, keeps the output tubes running cool and prolongs their life to a near-unbelievable 25 years. It also means you will never need bias adjustments. No wonder 275 Stereo comes with an ironclad five-year manufacturer's warranty on operation, parts, and tubes!

Akin to the company's Model 350, Crimson 275 Stereo listens to the room – a trait often referred to as the "speaker-microphone effect." Facilitated by a special current feedback loop, the amplifier can hear the room's reverb and unique sonic signature. By design, 275 Stereo uses the speaker as a microphone by using the speaker in reverse (the theorem of reciprocity) to listen to the room, thereby allowing a portion of the room acoustic to be expressed through the main speakers. As such, the room becomes an integral part of the music in a way solid-state amps do not permit. The resulting sound feels more majestic and realistic, and the soundstage larger and more compelling.

Stellar stability with any pair of loudspeakers, transformers with interleaved windings on adamantine steel with pure-nickel center sections, a ridiculous signal-to-noise ratio (110dB) that bests that of most transistor amplifiers, and a built-in meter on the front panel further raise the stakes of a tube amplifier whose features, quality, support, and sonics belie its price. Our 100% Music Direct Satisfaction Guarantee gives you every reason to audition it in your own home.

Carver's Unique U.S.A.-Made Output Transformer and the Solution to Magnetostriction
For some time now, Bob Carver has been working on a novel approach to manufacturing an output transformer. All transformers suffer from magnetostriction. This occurs when transformer noise is caused by a phenomenon that then causes a piece of magnetic sheet steel to extend itself when magnetized. When the magnetization gets taken away, it goes back to its original condition. To minimize the effect, quality transformers use a special steel alloy. Bob has come up with an alloy that, along with its magnetic nature and his proprietary winding technique, increases the efficiency and provides his company two options: Increase the power by using a larger version of the new design and sell the amplifier for $3,500 with a 150Wpc output. Or, the path Carver chose, use a smaller and lighter U.S.A.-made version that still provides up to 90Wpc and allows the price to be kept lower.
