The Onkyo M-5000R is a high-end power amplifier. This amplifier was designed by Onkyo to resemble their 1980s stereo models (the large front-panel analog power meters of this amplifier look like the classic M-405 model), and they promote it as offering the best of the traditional and modern. The AWRAT (Advanced Wide Range Amplifier Technology) design of this power amplifier is comprised of five aspects: a low negative feedback design (which helps to improve the frequency response), closed ground-loop circuits (which help to cancel individual circuit noise and keep the ground potential free of distortion), high instantaneous-current capability (which immediately cancels the speakers’ reflex energy and instantaneously send out the next signal, and also enables the amplifier to handle speaker impedance fluctuations), Dynamic Intermodulation Distortion Reduction Circuitry (DIDRC), which acts to to counteract unwanted high-frequency interference, and a Symmetrical Twin-Monaural Construction (which helps to minimize errors in stereophonic playback). The 8-ohm FTC rating is only 80 watts, but the M-5000R's current capabilities allow it to drive complex-impedance loudspeakers to high levels, with a dynamic power rating of over 450 watts into 1 ohm. There are color options available for the Onkyo M-5000R power amplifier.
