TEAC
VRDS-701
CD Player
(Pre-Order)

Commemorating the 70th anniversary of our founding, this model brings innovation and epitomizes TEAC strengths, including a newly-developed VRDS mechanism.

The VRDS-701 CD player employs a newly-developed VRDS mechanism and a TEAC original discrete DAC “TRDD 7”.
The VRDS is a TEAC-original CD drive mechanism that reduces rotation vibration and other unwanted vibration
by clamping the CD to an aluminum turntable with the same diameter in order to maximize inertial mass.

Furthermore, instead of an ordinary DAC IC for the DAC section, which is crucial to audio quality,
the VRDS-701 has a “TRDD 7” discrete DAC that incorporates our unique algorithms in a discrete circuit.

Unconstrained by conventional CD player definitions, the VRDS-701 is enhanced with future-forward functionality.
The ability to play MQA CDs using full MQA decoding capabilities and support for 22.5MHz DSD and
384kHz/32-bit PCM formats as a USB DAC are some of the features that make it more than just a CD player.

Newly-developed VRDS mechanism
Starting with a drive we developed that has a long record of use in professional applications, we added VRDS technologies, which are part of our TEAC legacy.

Vibration-Free Rigid Disc-Clamping System (VRDS)
This TEAC-original CD drive mechanism reduces rotation vibration of the disc itself as well as unwanted mechanism vibration by clamping the CD to an aluminum turntable with the same diameter and maximizing inertial mass in order to stabilize rotation. Servo current is reduced with the turntable by correcting disc warping and distortion and improving the relative optical axis precision of the pickup and disc pit side. This realizes reduced disc reading errors and outstanding audio quality.

Bridge section supports the VRDS
For the bridge that supports the turntable, we carefully selected lightweight materials that are very rigid and do not transmit vibration. By naturally settling vibrations quickly, we have realized a wide, dynamic sound. The bridge, which has a torus structure made of resin, is only fixed on one side, and propagation of vibration from the CD mechanism to the opposite side through the bridge is suppressed, so the entire mechanism minimizes unwanted sympathetic vibrations.

Semi-floating mounting
The entire CD mechanism is mounted on the sub-chassis in a semi-floating state. By controlling the transmission of vibrations between the CD mechanism and the chassis, the impact of sympathetic vibrations is abated, and natural playback sound is realized throughout the frequency range. By isolating motor vibrations from the main chassis, sympathetic vibrations within the chassis are prevented. At the same time, the CD mechanism is also isolated from external vibrations. Reading precision is also increased by isolating the CD mechanism from external vibrations.

Enhanced digital output
By eliminating the DAC function, the internal circuitry has been optimized for digital output. We have pursued higher audio quality by, for example, using larger components that did not fit in more limited space.

MQA CDs can be played back using the built-in MQA core decoder
The VRDS-701T has a built-in MQA core decoder and can digitally output MQA CDs at 88.2 kHz . Moreover, when used together with a DAC that has an MQA rendering function, playback using MQA full decoding is also possible.

10MHz external clock input
The 10MHz clock input allows synchronization with an external clock. In addition to improving audio quality during playback with the VRDS-701T, this also enables synchronization of the entire system with a clock generator.

Power supply enhanced using 2 high-capacity toroidal core transformers
Independent high-capacity toroidal core transformers are dedicated to the digital control section and the CD mechanism. These 2 high-capacity toroidal core transformers enable current to be supplied with greater stability.

Thorough design for vibration control
Power transformers, which tend to generate vibration, are mounted on a floating structure, separating and isolating them from the bottom panel. The side fins for heat dissipation have been tailored so that each one has a different length in order to eliminate sympathetic vibrations.

Three supporting pinpoint feet made of machined steel with a unique structure
The circuit board attachment screws have been kept to a minimum. Furthermore, steel pinpoint feet that use an original TEAC design with a new structure to provide a suitable amount of play in the connection between them and the bottom panel, are employed to thoroughly control vibrations that could affect audio quality.

Control connectors enable coordinated use with other devices
RS-232C is present for integration with popular control systems, and trigger input and output connectors enable power coordination with other devices.
