BOB CARVER AUDIO
200 Watt Mono Block Amplifiers – VTA 180M 

Bob Carver Audio designs & builds high quality, great sounding vacuum tube amplifiers. They custom build all their amplifiers by hand, the old fashion way and they use only the highest quality components available. Carver designs are all point-to-point wiring, no circuit board traces, no surface mount components, no connectors. Carver products are built to last a lifetime.

“These amplifiers stand with a small handful of the world’s great vacuum tube amplifiers” says Carver.

The VTA 180M mono block amplifiers are the perfect blend of form and function and the choice for serious music lovers. The VTA 180M is conservatively rated at 200 watts RMS into 8 ohms. The VTA 180M is designed to drive the most difficult to drive speakers. Extreme performance and Soundstage. High impedance input, automatic DC restorer circuit, a “set and forget” bias adjustment, low idle current, which increases output tube life. Ultra-wide bandwidth output transformers with interleaved windings capable of huge peak output capacity. Selectable feedback control allows the user to change the sound of the amplifier from vintage classical to modern contemporary.

From a listening perspective these amplifiers provide a fast tight bass, warm fluid mids, super smooth highs. Very three dimesional, holographic. Excellent depth of field, but refined. The special current feedback circuit design allows the amplifier to “listen to the room” via feedback from the speakers acting as microphones (using the law of reciprocity). The room speaker amplifier interaction provides a sense of remarkable ambience that is realistic and non fatiguing. The transformer output impedance allows the signal to follow the impedance curve of the loudspeaker, allowing a consistent voltage to be delivered to the loudspeaker at very low frequencies, a superb low end response!
