Reference CD player, preamplifier, and USB DAC • Newly developed VRDS transport mechanism • TEAC ΔΣ (Delta-Sigma) discrete DAC architecture • Dual-monaural, fully balanced circuit design • TEAC-QVCS analog volume control preamplifier • TEAC-HCLD2 high-current output line driver • Full MQA CD and MQA decoding • 10 MHz master clock synchronization input
The TEAC VRDS-701 Dual Monaural USB/DAC CD Player celebrates TEAC's 70th anniversary by pairing the company's legendary Vibration-Free Rigid Disc-Clamping System (VRDS) with flagship discrete digital decoding. At the core of the drive mechanism, an aluminum turntable firmly clamps the CD surface to suppress rotational vibration, correct disc warpage, and optimize the optical pickup's tracking accuracy. The digital stage is driven by the proprietary TEAC ΔΣ (Delta-Sigma) discrete DAC—built from an FPGA running proprietary algorithms and matched discrete resistor networks—bypassing standard integrated DAC chips to deliver rich, lifelike analog tonality. Featuring dual toroidal core power transformers, a dual-monaural fully balanced path, high-current TEAC-HCLD2 output buffers, and a variable TEAC-QVCS preamplifier stage, the VRDS-701 acts as a reference CD source and high-resolution digital hub.
Key Features & Innovations
Newly developed VRDS clamping mechanism — clamps the entire CD surface against a precision-machined aluminum turntable to eliminate rotational eccentricities, cancel disc warpage, and dramatically reduce reading servo errors.
TEAC ΔΣ (Delta-Sigma) discrete DAC — in-house developed discrete conversion circuitry utilizes custom FPGA algorithms and matched resistor networks, supporting native playback of DSD up to 22.5 MHz and PCM up to 384 kHz/32-bit.
Dual-monaural, fully balanced analog signal path — independent left and right circuits run completely isolated from the D/A conversion stage through the output terminals to prevent crosstalk and maximize channel separation.
Dual high-capacity toroidal power transformers — dedicated toroidal transformers feed the digital processing section and analog circuitry separately, eliminating electrical intermodulation and maintaining a silent noise floor.
TEAC-QVCS analog volume control preamplifier — Quad Volume Control System operates four variable-gain circuits (L+, L-, R+, R-) in 0.5 dB steps, enabling direct connection to a power amplifier without dynamic compression.
TEAC-HCLD2 high-current line driver buffers — high-current buffer amplifiers boast an ultra-fast slew rate to transmit signals through balanced XLR or unbalanced RCA interconnects with full dynamic transients intact.
Full MQA decoding and MQA-CD playback — hardware decoder supports native playback of MQA-CDs as well as high-resolution MQA streams received via USB, coaxial, and optical digital inputs.
10 MHz master clock input — 50-ohm BNC input allows synchronization with external 10 MHz reference master clock generators (such as the TEAC CG-10M) to minimize jitter.
FAQ — TEAC VRDS-701 Dual Monaural CD Player / USB DAC
How does the VRDS transport mechanism improve CD audio quality?
Conventional CD players hold a disc only by its center spindle, leaving the outer edge free to flutter, warp, and vibrate at high rotational speeds, which forces the laser pickup to constantly refocus and apply error correction. TEAC’s VRDS mechanism clamps the entire disc against a precision aluminum turntable, mechanically flattening the disc and stabilizing rotational inertia. This allows the laser pickup to track pits with optical precision, reducing jitter and tracking servo current fluctuations.
Can the VRDS-701 be connected directly to a power amplifier?
Yes. The VRDS-701 features TEAC-QVCS (Quad Volume Control System), a fully balanced analog resistor-ladder volume attenuator. By selecting variable output mode, you can connect the balanced XLR or unbalanced RCA outputs directly to a stereo power amplifier (such as the TEAC AP-701) or a pair of active studio monitors, bypassing the need for a separate preamplifier.
Does the VRDS-701 play SACDs (Super Audio CDs)?
No. The VRDS-701 transport mechanism is dedicated strictly to standard Red Book Audio CDs, CD-R/RW discs, and MQA-CDs. For high-resolution DSD and PCM listening, the onboard TEAC ΔΣ discrete DAC can be fed up to DSD 22.5 MHz and PCM 384 kHz/32-bit via its asynchronous USB Type-B input from a computer or music server.
What is the difference between the VRDS-701 and the VRDS-701T?
The VRDS-701 is a complete all-in-one digital hub equipped with the VRDS transport, the TEAC ΔΣ discrete DAC, an analog preamplifier, a discrete headphone amplifier, and analog RCA/XLR outputs. The VRDS-701T is a dedicated transport-only model that omits internal D/A conversion and analog circuitry, providing digital outputs (coaxial and optical) for use with external high-end DACs.
