Onkyo's New HiFi Separates Combine Classic Style, New Technology

Onkyo, a company with over 60 years of experience in quality audio, has announced a new range of elite hi-fi separate components with a style reminiscent of the company's classic stereo models of the 1980s. All three models, the P-3000R pre-amplifier, M-5000R power amplifier, and C-7000R CD player, incorporate Onkyo’s new Dynamic Intermodulation Distortion Reduction Circuitry (DIDRC) to counteract unwanted high-frequency interference.

Despite being beyond the normal range of human hearing, frequencies above 100 kHz are susceptible to clock pulses 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.

DIDRC works to reduce noise by improving linearity and reducing distortion in the super high frequency range, resulting in audio playback that is more faithful to the original source. DIDRC is incorporated into the amplification circuitry of the three hi-fi components.

To further reduce interference, these components feature separate digital and analog circuitry. Other features common to all models include audiophile-grade parts—such as massive toroidal transformers and gold-plated terminals—along with a new circuit board construction and separate chassis panels, to eliminate unwanted vibrations.

P-3000R Preamplifier
The P-3000R pre-amp accepts both analog and digital sources, with connectivity options including AES/EBU digital connectors and a USB input for PC audio. A high-quality 32-bit Burr-Brown DAC is provided for each stereo channel, to optimize audio performance. Meanwhile, PLL (phase locked loop) technology minimizes the effect of clock jitter, and bi-amping capability provides greater flexibility for audiophile applications.

M-5000R Power Amplifier
Onkyo’s new M-5000R offers the best of the traditional and modern, with large front-panel analog power meters reminiscent of Onkyo's classic M-405 from the 1980s combined with state-of-the-art distortion reduction technologies and exceptional high current capabilities.

The company's advanced AWRAT amplification design is at the heart of the M-5000R power amplifier. AWRAT comprises DIDRC technology along with a low NFB design, closed ground-loop circuits, and high instantaneous-current capability. While the 8-ohm FTC rating is a conservative 80 watts, the amplifier's remarkable current capabilities allow it to drive even the most demanding complex-impedance loudspeakers to high levels, with a dynamic power rating of over 450 watts into 1 ohm. To minimize errors in stereophonic playback, the M-5000R uses a perfectly symmetrical alignment of power devices for the left and right channels.

Power efficiency on the M-5000R is optimized by three-stage inverted Darlington circuitry and a new Quad Push-Pull amplification design that incorporates two extra transistors for each channel. Meanwhile, twin toroidal transformers and four 27,000 µF capacitors work to stabilize the power supply and current, respectively. A high-grade XLR input opens up the possibility of doubling power output via a BTL (bridged transless) set-up.

C-7000R CD Player
To ensure minimal signal interference, the C-7000R CD player employs a thermally regulated, high-precision clock with a state-of-the-art crystal oscillator. To further reduce potential interference, the player can be operated in analog-only or digital-only mode. Furthermore, analog and digital circuitry are physically separated and employ independent transformers: a massive toroidal transformer for analog, and an EI transformer for digital. The audiophile build-quality of the C-7000R is epitomized by a silent disc mechanism, a solid die-cast aluminum tray, and AES/EBU digital outputs.

With these three precision-engineered hi-fi components, Onkyo offers a compelling choice to music aficionados seeking a no-compromise audio solution.

All three models will be available through select Onkyo dealers in January , with manufacturer's suggested retail prices of $1,699 for the P-3000R pre-amplifier, $2,499 for the M-5000R power amplifier, and $1,499 for the C-7000R CD player.
