The CHALLENGER

The CHALLENGER series of monoblocs are the foundation of the AudioValve range of amplifiers, which have been refined and perfected since first introduced in 1987.

The CHALLENGER is unique in so many key areas. For example, it can use KT-88s, 6550s or EL-34s with equal ease as power tube. And depending on the tube used, its output can range from 110 wpc to as high as 180 wpc. This is made possible by our revolutionary and proprietary ABR circuitry, which monitors, biases and controls each tube independently in the most AudioValve power amplifers.

This feature allows the use of any of the mentioned tubes or, indeed, a combination of any of the three. This redefines in a truly innovative way the concept of "plug and play." It also makes tube replacement very economical, as there is no need for costly and exotic tubes which have to be matched in order to get the best sound from the amplifier.

Another truly impressive detail . That is, the circuitry is totally balanced from input right to output terminals. All of this means the CHALLENGER can drive any speaker on the market, from conventional drivers to exotic electrostatics and ribbons, with complete ease.

The most recent affirmation of the beauty and prowess of this truly unique and great amplifier came in the November 1999 issue of The Absolute Sound, one of the most respected industry magazine in the world.

AudioValve Challenger combine also excellente with electrostatic speakers.
