Brand: Audiovalve

The AudioValve Challenger 250 is a high-end tube amplifier designed for audiophiles and music enthusiasts. This amplifier has a power output of 250 watts per channel, capable of delivering crystal clear sound with exceptional detail and dynamics. The design of the Challenger 250 is based on traditional valve (tube) technology, which AudioValve has been refining for years.The heart of the Challenger 250 is the push-pull KT120 valves in the output stage, complemented by matched pairs of 6H30 valves in the drivers and input stages. These valves are hand-selected and matched to ensure optimal performance. The capcity to optimize component matching is a hallmark of AudioValve technology, and a key factor in achieving the highest possible sound quality.The Challenger 250 also features an advanced auto-bias circuit, which ensures reliable and stable operation of the valves. This eliminates the need for manual bias adjustment and decreases the risk of damage to the amplifier due to misadjustments or instability in the valves.A unique feature of the Challenger 250 is the built-in fight against microphonic noise, which can be an issue with tube amplifiers due to vibrations caused by external sources. The amplifier's microphonic noise reduction circuit measures the vibration input from the tubes and generates an opposite voltage to cancel the effect of the vibrations on the audio signal.Finally, the AudioValve Challenger 250 is built to the highest possible standard of craftsmanship and components, ensuring decades-long operation with minimal maintenance required. The amplifier is designed to deliver the finest sound quality possible, with an unrivalled balance of power, detail, dynamics, and warmth.In summary, the AudioValve Challenger 250 is a high-end tube amplifier with exceptional sound quality, hand-selected and matched valves, advanced auto-bias circuit, microphonic noise reduction circuit, and outstanding craftsmanship. It is an excellent choice for audiophiles and music lovers seeking the highest possible level of audio performance.
