Doshi Audio Evolution Monoblock Power Amplifier

The Doshi Evolution Monoblock Amplifiers will change your perception of what a tube amplifier can achieve. These Class A amplifiers harness the power of four KT150 tubes per chassis to output a massive 160 WPC. The unique circuit design of these monoblocks allow them to compete with the very best solid state amps in terms of speed, eerily black background, dynamics, and bass slam. At the same time, these monoblocks are not just about brawn. They convey the beauty and magic of the music for which tubes are known by bringing to light the shape and texture to transients, colour to timbre, and humanity to voices. These amplifiers are easy to use via their front panel push button bias settings and microprocessor control and protection.

Built upon the world-wide acclaim of the Doshi V3 Monoblocks, the Evolution embodies many significant improvements. Perhaps the most significant improvements are to the power supply. Evolution monoblocks use a larger transformer, passive power factor correction, schottky rectifiers, larger power supply capacitors and have redesigned input and driver circuitry for lower feedback and higher bandwidth. Other significant improvements include the strategic implementation of custom ClarityCap© CMR capacitors and a new aluminium constrained layer top provides better vibration isolation.
