Onkyo Expands Stereo Separates Selection With Retro Cosmetics

Las Vegas - Onkyo is going retro, expanding its selection of stereo component separates with three models whose styling is reminiscent of the brand's 1980s models but whose technology is from the 21st Century.

The three components are the $1,699-suggested P-3000R pre-amplifier, $2,499 M-5000R power amplifier, and $1,499 C-7000R CD player. All will be available this month through select dealers.

All of the separates feature new Dynamic Intermodulation Distortion Reduction Circuitry (DIDRC) to prevent high-frequency interference above 100kHz, which is beyond the range of human hearing but which are susceptible to clock pulses and other types of distortion that can generate "beat interference," which "affects the character or atmosphere of the original sound," the company said. DIDRC is incorporated into the amplification circuitry of the three hi-fi components.

To further reduce interference, the products feature separate digital and analog circuits.

 Other features include such audiophile-grade parts as massive toroidal transformers. A new circuit board construction and separate chassis panels are designed to eliminate unwanted vibrations.

The P-3000R pre-amp accepts analog sources as well as digital sources via AES/EBU digital connectors and a USB input. A high-quality 32-bit Burr-Brown DAC is used for each channel and the component can be bi-amped.

The M-5000R amp offers large front-panel analog power and high-current capabilities. AWRAT amplification design consists of DIDRC technology along with a low NFB design, closed ground-loop circuits, and high instantaneous-current capability.

 It's rated at 2x80 watts into 8 ohms using FTC standards, but it can also drive demanding complex-impedance loudspeakers to high levels with a dynamic power rating of more than 450 watts into 1 ohm, the company said.  Power efficiency is enhanced via a three-stage inverted Darlington circuitry and a new quad push-pull amplification design that uses two extra transistors for each channel. An XLR input opens makes it possible to double power output via a BTL (bridged transless) set-up.

The C-7000R CD player uses a thermally regulated clock with crystal oscillator to reduce potential interference. Also to reduce potential interference, the player can be operated in analog-only or digital-only mode, with analog and digital circuitry physically separated.

The C-7000R also features a silent disc mechanism, die-cast aluminum tray, and AES/EBU digital outputs.
