Commemorating the 70th anniversary of TEAC's founding, this model brings innovation and epitomizes TEAC's strengths, including a newly-developed VRDS mechanism.
Newly-developed VRDS mechanism
TEAC started with a drive they developed that has a long record of use in broadcast applications, while also adding VRDS technologies, which are part of our TEAC legacy.
Including: Vibration-Free Rigid Disc-Clamping System ( VRDS), a Bridge section supporting the VRDS, and a Semi-floating mounting
TEAC ɅƩdelta-sigma discrete DAC
Instead of an ordinary DAC IC, the DAC section, which is critical for determining the sound, is a TEAC ΔΣ (Delta Sigma) discrete DAC that consists of a discrete circuit structure that incorporates our unique algorithms using FPGA. DSD signals are left as is, while PCM signals are transmitted after passing through the ΔΣ modulator and converation to either 1-bit or multi-bit signals; according to the end users choosing. The sound field that is wide and perfectly clear can be realized only because of this discrete design. The result is that TEAC can say they have achieved the sound sought by TEAC. With a TEAC ΔΣ discrete DAC, playback of 22.5MHz DSD and 384kHz/32-bit PCM data is possible.
Dual mono structure
Using the independent left and right toroidal core transformers, TEAC has employed an indulgent dual mono structure for the circuitry from the power supply circuit through the D/A converter section to the analog output stage.
The dual mono structure has two sets of circuitry that provide complete mono paths for each channel. This prevents interference between the left and right signals and realizes rich musical expression that emphasizes the perception of the sound space and three-dimensionality.
Fully-balanced transmission at every stage
Fully-balanced transmission of the left and right analog output signals from D/A conversion to the final output stage contributes greatly to improving the signal-to-noise ratio and extending the dynamic range. The sense of air that high-resolution audio sources have can be transmitted without loss in an even purer state.
Direct connection is possible with power amplifiers that use TEAC-QVCS
TEAC-QVCSThis player can be directly connected to a power amp and used without a preamp due to the inclusion of TEAC-QVCS, which is an analog variable gain amp type attenuator with a fully-balanced structure.
TEAC-QVCS (Quad Volume Control System) is a variable gain amp type volume control comprised of four discrete left, right, positive and negative (L+, L–, R＋ and R–) circuits. This theoretically prevents "gang errors" (level discrepancies between left and right channels at low volumes) and enables extremely precise analog volume adjustment in 0.5dB increments from–95 dB to ＋24 dB.
The two sets of analog outputs (balanced/unbalanced) can be set to fixed or variable output.
Inclusion of an MQA full decoder enables MQA CD playback
MQA (Master Quality Authenticated) is a high-quality audio codec for playing music with the uncompromised quality of the master captured in the studio. The VRDS-701 includes an MQA decoder that controls waveforms converted from digital to analog at a precision as high as 5ms in order to achieve analog waveforms that are more faithful to the original sound sources. By greatly reducing “temporal blur,” which tends to occur at points when sound pressure differences are extreme, including when sounds begin suddenly, playback sound that is close to the original source in terms of human hearing can be achieved. The inclusion of an MQA full-decoder not only enables enjoyment of MQA CDs, it also makes decoding of MQA data from the digital inputs possible, allowing playback of MQA files from a computer when used as a USB DAC.
As a USB DAC, 22.5MHz DSD andr 384kHz/32-bit PCM data can be played back
A USB Type-C port is available for digital input. The VRDS-701 is much more than a CD player. Connected to a computer with USB, it can be used as a USB DAC, enabling enjoyment of the computer audio world with high-resolution audio sources.
2×, 4× and 8× upconversion using RDOT-NEO
RDOT-NEO (Refined Digital Output Technology NEO), which smoothly augments digital audio signals, provides a function to upconvert the sampling frequency of PCM digital signals 2×, 4× or 8× (up to 384 kHz). RDOT, which applies an analogous interpolation method using fluency logic, is a technology that was developed to enable the playback of the frequencies higher than 20 kHz that are lost by the 44.1kHz/16-bit CD format. Based on the information read from the CD, analogous data is generated between the waveform samples. As a result, data above 20 kHz is also generated
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-701, this also enables synchronization of the entire system with a clock generator.
TEAC-HCLD２ enhanced-current output buffer amp circuit
For the analog output circuit, the TEAC-HCLD 2 circuit is an enhanced-current output buffer amp that increases crucial current transmission capability. This model uses diamond buffer amps with high current output capacity as line drivers. By using a positive-negative two-circuit structure for each channel, drive can be differential with balanced output and parallel with unbalanced output. Transmitting audio signals without degrading their dynamism becomes possible with increased current supply capacity.
Headphone amp
The headphone amp has a dedicated driver that uses a high-output circuit with low distortion, high signal-to-noise ratio and a high 2000V/μs through rate, equivalent to a current transmission enhancing output line driver. This will maximize the potential of your headphones.
High-precision dual clock for 44.1kHz and 48kHz multiples with low phase noise
This player has low-phase-noise type high-precision crystal oscillators. Along with 44.1kHz for CD playback, it supports a 48kHz clock, which is necessary for playing files from a computer when used as a USB DAC.
Bulk Pet USB communication technology enables stable data transmission
When sending vast quantities of digital data for high-resolution audio sources through USB cables, large discrepancies can occur in the processing loads of both the transmitting computer and the receiving USB DAC. This creates the possibility of the sound breaking up and other problems. Using Bulk Pet USB transmission technology, however, achieves constant transmission at a fixed data volume, enabling steady data transmission by smoothing the loads for processing on both ends. Since the audio quality can be altered by changing the load on the computer, four preset transmission modes can be chosen according to the desired audio quality.
TEAC HR Audio Player provided free
High-resolution audio sources, up to 22.5MHz DSD or 384kHz/32-bit PCM, can be easily played from Windows and Macintosh computers using this free dedicated software. Digital audio data can be transmitted with certainty under the best conditions by simply starting the software and selecting the VRDS-701 that is connected using a USB cable.
Since the software is designed for use with this product, making USB audio settings is trouble-free.

Read Time: Approx. 10 min.
In Depth Comparison of 2 TEAC CD Transports vs. the VRDS-701 CD Player & USB DAC
CDs are back! Yep you read that right, CDs are hip again.
It's time to blow the dust off your beloved CD collection because audiophiles have made CD transports hip again! Yep, CD transports are back and we're comparing two TEAC CD transports, the VRDS-701T and PD-505T vs the VRDS-701 CD Player — Let's get to it!
TEAC CD Player Comparison: VRDS-701, VRDS-701T & PD-505T
TEAC VRDS-701 CD Player, USB DAC Unboxing
"Who said CDs are dead? In a lot of cases, I prefer the sound of a well-designed CD Transport over music streaming. Vibration is a huge enemy when it comes to maintaining a stable CD Transport and preventing tracking errors on the drive. The VRDS transport mechanism is among if not the best in the business — Used by many of the top brands out there. TEAC continues to push the boundary of performance at a very fair price point, thanks to the trickle-down technology from parent company Esoteric. Can't afford Esoteric? No problem, I could easily live with a Teac CD Player or Transport for the rest of my life!!"
Design
Starting with design, all three of these units have a similar look — A Matte black chassis with two handles that I will assume are to help safely move the unit and three supporting steel pinpoint feet that provide a stable placement. This is a TEAC original design that they say controls vibrations that could affect audio quality. They also all have a display screen, CD tray, on/off switch, and several command buttons like pause/play, stop, and menu.
Priced at $1,399 the PD-505T CD Transport is the smallest unit in this lineup at almost half the size and weight of the VRDS-701T Transport. The PD-505T has an entire metal enclosure making it resistant to external noise and the intrusion of electromagnetic noise from computers and other devices. Thanks to the unit's small form factor you can place it on a desk, side table, and any other small spaces.
The front panel of the PD-505T has six command buttons for the menu, ejecting the CD tray, track skipping, pause/play, and stop. The back panel features a coaxial RCA output and optical output, clock sync input, and power input.
As mentioned earlier, the VRDS-701T CD Transport, which goes for $2,699, is larger than the PD-505T at 22 pounds. It's got a smaller display screen than the PD-505T but its larger front panel makes room for more command buttons. On the VRDS-701T you'll find the following buttons: A CD tray ejection, pause, play, and stop button, a menu button, a play mode button, a repeat button, as well as a track skipping knob. On the back panel is a coaxial and optical output, clock sync input, a trigger input and output, RS232 control and USB firmware port, and power input.
At $3,799.99 the VRDS-701 is the ultimate all-in-one high-quality unit with a CD Player and USB DAC. It's almost the same size as the VRDS-701T but it's the heaviest unit at 26 pounds. On the front panel is a stop, play and pause button. As well as a menu button, source button, and play mode button. There's also a track skipping knob, volume knob, and 6.3mm headphone output. It's the only unit capable of audio playback thanks to its internal DAC and internal headphone amp. The back panel of the unit features an analog XLR output and RCA output, a USB type-C input, a coaxial input, an optical input, and a clock sync input. There's also a coaxial and optical output as well as a trigger output and power input.

Sound
Let's talk about the sound quality. The PD-505T and VRDS-701T are dedicated CD transports. They have no internal DAC, headphone amplifier, volume control, or headphone jacks so we've paired them with the TEAC UD-701N Headphone Amplifier & USB DAC with the TEAC CG-10M Master Clock. The VRDS-701 is an all-in-one unit with an internal DAC and headphone amplifier.
The VRDS-701 and UD-701N both use TEAC's Delta Sigma discrete DAC so sonically both units sound practically the same. The reason I say this is there is a preamp stage in the UD-701N that may make a small difference between the two units with RCA/XLR outputs. The PD-505T and VRDS-701T were connected to the UD-701N as the source unit and I listened in a single-ended output.
The Delta Sigma discrete DAC delivers a sound that's wide and organic with plenty of detail and a nice dynamic range. I paired the units with the Meze Empyrean Headphones and our Silver Dragon Headphone Cable. Given that the UD-701N and VRDS-701 use the same DAC I didn't hear any noticeable differences when I compared the two CD transports to the VRDS-701.

If I'm being honest I can't say that I've listened to a CD since I got my first iPod over a decade ago so I was utterly shocked to hear some of my childhood favorites in breathtaking fidelity. Details I hadn't heard before were suddenly brought to the front and there wasn't any added warmth to the sound that negatively colored it. I want to reiterate that these sound impressions are from the Delta Sigma discrete DAC in the VRDS-701 vs. UD-701N that drove the PD-505T and VRDS-701T transports. The CD Transports do not have coloration. The addition of an external clock corrected any timing errors with the transports and added an airiness to the sound but did not drastically impact it.
So let's shift focus and briefly talk about the VRDS-701. With multiple source modes and a built-in CD player, I was able to listen to the same songs on a CD then stream them via USB. Sonically, the VRDS-701's CD player and the two CD transports delivered the same great sound with no degradation in quality between the three units. The sound differences between the VRDS-701's USB mode and CD mode were subtle. In USB mode everything was slightly elevated. A little more detail, dynamics, and so on. If you blind tested the two modes it would take a well-trained ear to notice any differences. Mind you, this is when the streamed songs are being played in CD quality — If you were to stream the hi-res version of a song and then listened to the CD version you're going to notice some changes.
So if you're seeking a borderline analytical sound with some nice bottom-end presence then you'll enjoy the VRDS-701. The main differences between these units lie in their features, technology, and ergonomic scenarios which we'll jump right into!

Technology & Features
Earlier, I briefly mentioned that the PD-505T and VRDS-701T are dedicated CD Transports, meaning you will need to externally connect a DAC and headphone amp to the units. The VRDS-701T has been specifically optimized for digital output and TEAC recommends the UD-701N USB DAC Network Player as the ultimate companion for the VRDS-701T. This is only a pairing suggestion by TEAC, the VRDS-701T can be used with any DAC and integrated into any system.
The PD-505T, VRDS-701T, and VRDS-701 all have a 10MHz external clock input allowing users easy integration with systems that are synced using an external clock. The PD-505T has dedicated power supplies for the OLED display, CD drive and microcomputer circuit, as well as the audio circuit. Toroidal core transformers are used for the power supplies. The unit can play CD-R/CD-RW discs that are in audio CD format and the unit has a crystal-oscillator-based internal clock that accurately reproduces the original sound stored on the CD. You can pair the PD-505T with a TEAC reference 500 series DAC, as well as any external DAC of your choosing.
The VRDS-701T features TEAC's latest VRDS technology. VRDS stands for Vibration-Free Rigid Disc-Clamping System (VRDS) which reduces the rotation vibration of the disc 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. In short, this technology ups the game, going to all lengths to reduce the potential of any jitter and noise. Two high-capacity toroidal core transformers are dedicated to the VRDS-701T's digital control section and CD mechanism, and the unit has a built-in MQA decoder. When paired with the UD-701N MQA full-decoding is possible.

The VRDS-701 is the most technology and feature-rich unit in this lineup. Just like the VRDS-701T, it also features the VRDS technology from TEAC. The VRDS-701 has independent left and right toroidal core transformers for the circuity from the power supply through the D/A converter section to the analog output stage. There are also independent high-capacity toroidal core transformers for the CD mechanism and digital control section.
The inclusion of TEAC QVCS technology enables the VRDS-701 to be connected directly to a power amplifier. QVCS, which stands for Quad Volume Control System is an analog gain amp-type attenuator with a fully balanced structure that prevents discrepancies between left and right channels at low volumes. The USB type-C port on the back of the VRDS-701 enables users to connect the unit to a computer with USB and use it as a USB DAC. Dedicated TEAC software allows users to play high-resolution audio sources up to 22.5MHz DSD or 384kHz/32-bit PCM from Windows and Mac computers. Digital audio data can be transmitted with certainty under the best conditions when connected using a USB cable.
The VRDS-701 has a high-precision dual clock that supports 44.1kHz for CD playback and 48khz for playing files from a computer when used as a USB DAC. There's also a fully-balanced transmission of the left and right analog output signals from D/A conversion to the final output stage that helps improve the signal-to-noise ratio and extend the dynamic range.
Dragon Audio Cables
[Black Dragon Coax Digital Cable, Blue Dragon Power Cable, Silver Dragon USB Cable]
Let's talk audio cables because your new TEAC setup will need some. At Moon Audio our Dragon Audio Cables are handcrafted daily in our Cary, NC headquarters with the highest standards and made to order according to your specific needs. We'll create a custom cable for you using the highest quality UP-OCC silver or copper conductors that can be manufactured. When you're spending upward of $5,000 on a new piece of gear I imagine the last thing on your mind is all the accessories you've got to buy to go with it.
So for these CD Transports, our Black Dragon Coax Digital Cable with 75 Ohm impedance and RCA connectors was used to link the CD Transports to the UD-701N Headphone Amp and USB DAC.
To power each TEAC unit we used our Blue Dragon Power Cable. The durability of our power cable will withstand many variations of your everchanging audiophile setup and its double shielding will help ward off all outside interference. Our Black Dragon Coax Digital Cable with 50 Ohm impedance and BNC connectors connected both TEAC CD Transports to the TEAC CG-10M Master Clock, providing a stable connection free of interference. And lastly, we use our Silver Dragon USB Cable to compare the VRDS-701's streaming and CD data transfer.
I opted to pair the Meze Empyrean Headphones with our Silver Dragon Premium Headphone Cable. Each of our Dragon Audio Cables has its own sound signature and the Silver Dragon adds clarity and detail to your headphones with breathtaking resolution. If that sounds like something you'd enjoy then the Silver Dragon is a great choice, but it's all up to preference so you can't go wrong with any of our Dragon Audio cables. If you want more bottom-end weight then opt for the Black Dragon Premium, or if you want the most neutral sound without any coloration, give our Blue Dragon Premium Cable a try. Our Premium headphone cable line offers the same quality construction as our standard Dragon cables, but with extras like Premium Mundorf solder and premium rhodium-plated Furutech connectors that look and feel great while you listen.
I used a Dragon Premium Cable with a 6.3mm connector but you can customize the cable length and connector options to fit your setup. We're flexible and we love to offer our customers the ability to customize their cables — So if you're not sure what connector you need or which dragon sound signature suits you best, we're always here to help!
Generally, stock audio cables are manufactured with subpar materials, metals with impurities, poor geometries, and an overabundance of layers to make them look and feel like a fire hose. Inconsistency and lack of quality control in stock cables can lead to poor sound quality and a veiled sound vs. what the musician intended for you to hear and feel from the music. Dragon Audio Cables are handcrafted with the highest standards and made to order according to your specific needs. At Moon Audio, we create a custom cable for you using the highest quality UP-OCC silver or copper conductors that can be manufactured. UP-OCC metals are void of impurities and are optimized for signal transfer and sound quality. We have one of the largest collections of audio and headphone connection options available online and we create limitless audio cable options depending on your specific gear and needs.
