ONKYO C-733 CD Player Tested and working well, in good condition F/S

Powerful sound imaging. CD player equipped with a high-precision super-precision clock

The clock section, which synchronizes all digital circuits, features a "Super Precision Clock" circuit utilizing a crystal oscillator boasting an oscillation frequency deviation of ±1.5PPM at room temperature (over 10 times more precise than players in the same class). Each unit is meticulously hand-adjusted at the factory to reproduce rich realism and soundstage presence. It also incorporates high-grade audio specifications: an ultra-low-vibration loading mechanism to prevent interference with subtle nuance reproduction; a power transformer with independently wound secondary coils to block noise intrusion from the drive and digital circuits into the audio circuitry; a robust 1.6mm-thick bottom chassis; and gold-plated RCA terminals.

Ultra-High-Precision Super Precision Clock

The clock synchronizes all digital processing, acting like an orchestra conductor. This clock section employs a crystal oscillator with a frequency deviation of ±1.5PPM (parts per million) at room temperature. Compared to the ±50PPM oscillators common in this class, this offers an order of magnitude higher precision, achieving soundstage imaging that reveals every detail. Furthermore, to push precision to its absolute limits, each unit undergoes meticulous manual adjustment at the factory before shipment.

VLSC: Significantly Suppresses Noise Intrinsic to Digital Devices

LPFs (low-pass filters) are typically used to suppress pulsed noise generated during the D/A conversion of CD digital signals. However, this circuit proves insufficient, leaving residual noise that degrades sound quality. The patented "VLSC (Vector Linear Shaping Circuitry)" employs a circuit that completely ignores the noise's inherent positive-negative symmetrical ultra-high frequencies. This achieves substantial suppression of pulsed noise. By breaking away from the conventional LPF processing, it maximizes the potential of digital audio technology, successfully reproducing even the most delicate sound components with precision.
