Description :
The Denon PRA-2000 preamplifier is the first of Denon audio product to come out with features developed for real time audio technology guiding concept. It is considered by many to be one of the very best sounding machines in its day. It aims to produce music that can be more realistic to life than is possible with the audio technology. The overall look of the the Denon PRA-2000 has nothing too distinguished and looks to be simple in operation. It comes with 3 phonos, Aux, Tuner and Pre Out/Off. Each selector switch can be activated by just a light touch. They are arranged in positions isolated from the the audio signal wiring, so that the switches do not influence the quality of sound. The Denon PRA-2000 is crafted with innovation and engineering excellence, and is designed to match with the Denon POA-3000 with a single goal in mind: to maximize the entertainment experience.
