Onkyo announced a new range of elite hi-fi separate components with a style reminiscent of the company's classic stereo models of the 1980s. The P-3000R preamplifier, 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.
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.
Price and Availability
The Onkyo P-3000R Preamplifier will be available January 2011 for $1,699.
