جهاز سي دي بالير مستعمل مثل الجديد بجودة خرافية من اونكيو
The Onkyo C-7000R Reference CD Player is an absolute tank of a source component. Released as part of Onkyo's
premium, audiophile-grade "Reference" line, it is engineered with a level of mechanical over-design that you rarely see in standard consumer gear.
If you are looking to integrate a high-end physical transport or an exceptionally clean analog player into a serious listening space, this unit represents serious high-fidelity engineering.
Key Engineering Highlights
- Dual-Mono DAC Architecture: It houses two flagship TI Burr-Brown 24-bit/192kHz (PCM1792) DAC chips. Instead of running stereo off one chip, Onkyo runs them in a dual-mono configuration (one dedicated chip per channel) to achieve near-perfect channel separation and minimize cross-talk.
- Complete Digital/Analog Isolation: The digital processing and analog output stages are completely separated physically, down to the power delivery. It uses a massive, heavy Toroidal transformer specifically for the clean analog output stage, and a separate EI transformer for the digital side. This eliminates power line noise bleeding from the digital clock into your analog signal.
- Vibration Control: Weighing in at a heavy 12.0 kg (26.5 lbs), the chassis uses separate, thick, anti-resonant aluminum panels for the top, front, and sides rather than a single bent-sheet metal cover. The silent, die-cast aluminum disc tray is stabilized on four rigid machined brass pillars to absorb internal rotational vibrations.
- Professional Clocking & Jitter Reduction: It relies on a thermally regulated super-precision clock crystal (keeping frequency drift under $\pm1.5\text{ ppm}$) paired with Phase-Locked Loop (PLL) ultra-low jitter technology.
- DIDRC Technology: Onkyo's proprietary Dynamic Intermodulation Distortion Reduction Circuitry tackles ultra-high-frequency digital noise (above 100 kHz). While we can't hear those frequencies directly, reducing artifacts there prevents "beat interference" from muddying the audible spectrum, resulting in a cleaner, more spacious soundstage.
Connection Options
On the rear panel, you get a premium selection of outputs:
- Analog: Wide-spaced, gold-plated, machined solid brass RCA jacks.
- Digital Outputs: 1 x Optical (Toslink), 1 x Coaxial (S/PDIF), and a professional Amphenol AES/EBU (XLR) digital output.
