Our Price: £749.00

Select Colour

Overview

The K2 stereo power amplifier is derived from the K2 integrated and sets the new standard for affordable hi-end power amplifiers. This power amplifier is refined way beyond expectation providing a powerful, punchy yet delicate and musical sound full of dynamics and timber. The sound stage and musicians have the realistic scale and 'air' about them that is achievable by only a few of the very best power amplifiers regardless of cost.

The new K2 power amplifier benefits from totally revised internals. The mains transformer and the AC circuitry utlise improved components and layout. The switchable input selects between Straight or Trimmed allowing full gain adjustment when used with other amplification .The new circuitry provides immense power with excellent resolution and negligible distortion. The music through the K2 stereo power amplifier is powerful, engaging and with exceptional timing. This is an excellent stand-alone Power Amplifier which is also a perfect match for the K2 Integrated Amp in multi-amp configuration.
