TEAC's CD player, renowned for its high-end audio equipment, features a unique conical-bottom design and employs a high-rigidity, high-mass damping structure to eliminate adverse effects from vibration and resonance. The DAC utilizes the Philips SAA7350, a 1-bit bitstream DAC chip. This is the same bitstream DAC chip found in the legendary Philips DAC7, a D/A converter once featured in high-end systems of yesteryear. It is highly regarded for its clear, expansive sound quality, rich bass, and exceptional depth with superb harmonic expression. Furthermore, the crystal oscillator for the master clock, essential for driving the bitstream DAC with low jitter, has been replaced with a TCXO (Temperature-Compensated Crystal Oscillator) with 0.1 PPM accuracy. Precision-grade metal film resistors with a tolerance of less than ±1%, typically used in measuring instruments, are employed throughout this unit, ensuring stable operation and clear sound quality. This unit's op-amp drive voltage is 30V (±15V), fully unleashing the performance of the high-fidelity OPA827AIDR op-amp. Most failures in audio equipment stem from degraded electrolytic capacitors. This unit has undergone overhaul and high-fidelity upgrades, with all electrolytic capacitors replaced with audio-grade components. This ensures it will continue to provide reliable service for years to come.
