M-5000R BLACK Hi-end 2CH Power Amp Onkyo

THIS PRODUCT IS FOR ONLINE ORDER ONLY. ONKYO M-5000RB STEREO POWER AMPLIFIERA visceral power amplifier breaking new ground for audiophile grade build and performance. The M-5000 is meticulous in it's pursuit to bring you the best signal quality possible with the new AWRAT technology while efficient power output is coordinated by the three-stage Darlington circuitry. Stable current and power achieved by the Massive twin toroidal transformers and four 27000 ÃŽ¼F capacitors. It's design might remind you of days past but the construction uses efficient techniques with totally symmetrical alignment of power devices for left and right channels helping to eliminate stereophonic playback errors.AWRAT (Advanced Wide Range Amplifier Technology)The M-5000R employs a host of proprietary Onkyo technologies to ensure optimal audio performance.1. DIDRC (Dynamic Intermodulation Distortion Reduction Circuitry) Since the advent of digital audio signal-to-noise ratios have improved dramatically. However the S/N ratio reflects static noise only and takes no account of another type of noise that occurs as the byproduct of sound reproduction‚¬ï¿½dynamic noise. To reduce this type of noise Onkyo has developed DIDRC technology for use in our hi-fi components. Despite being beyond the normal range of human hearing frequencies above 100 kHz are susceptible to clock pulse and other forms of distortion from digital devices. Such distortion in the super high frequency range can generate beat interference which in turn affects the character or atmosphere of the original sound. By improving linearity and reducing distortion in the super-high frequency range Onkyo's new DIDRC technology effectively reduces perceptible noise.2. Low Negative-Feedback Design Too much NFB makes a system susceptible to counter-electromotive force from the speakers resulting in a drop in perceived sound quality. To avoid this Onkyo focuses on improving the frequency response and reducing distortion without relying so much on NFB.3. Closed Ground-Loop Circuits The M-5000R employs a sophisticated closed-circuit design in which each circuit has a separate link to the power supply. This helps to cancel individual circuit noise and keep the ground potential free of distortion.4. HICC (High Instantaneous-Current Capability) Handling current loads up to 150 amperes HICC enables an amplifier to immediately cancel the speakers' reflex energy and instantaneously send out the next signal. The same high current required to achieve this also supports the amplifier's ability to handle speaker impedance fluctuations.5. Symmetrical Twin-Monaural Construction Power devices for the left and right channels of the M-5000R are aligned symmetrically. Each channel has the same electrical and structural design and signal pathways are uniform in length. This helps to minimize errors in stereophonic playback.Quad Push-Pull Amplification Design with Three-Stage Inverted Darlington CircuitryThree-stage inverted Darlington circuitry brings greater efficiency to the M-5000R power amp by employing a low-NFB design to maintain voltage stability and enhance transient response. Extremely sensitive to oscillations this circuitry requires very advanced control technology in order to be incorporated into the amplifier. Breaking further new ground the M-5000R employs two extra transistors for each channel in a quad push-pull design that significantly enhances amplification power.Audiophile-Quality PartsThe M-5000R incorporates two massive toroidal transformers that reduce magnetic flux leakage improve efficiency and keep the power supply stable. Also on-board are a sub-transformer and four 27000 microfarad capacitors that work to make the current significantly smoother. Gold-plated machined solid brass terminals ensure an extremely clean connection.
