TEAC UD-505-X USB DAC Headphone Amplifier

ESS Technology ES9038 Q2M high-performance DAC supports resolutions up to 22.5MHz DSD and 768kHz/32bit PCM

We have employed one DAC chip, which is a crucial component for digital audio, in each of the stereo channels. The ESS Technology ES9038Q2M SABRE32 Reference DAC that we use has a strong reputation in the high-end audio market. Using 32-bit HyperStream® II DAC architecture and Time Domain Jitter Eliminator, which are ESS original technologies, an outstanding dynamic range is realized and linearity is increased in the D/A conversion. As a result, clear and accurate audio playback with superior.

Dual monaural circuit design and fully-balanced design

A dual monaural circuit configuration is used throughout, from the power supply (including power transformers), to the D/A converters in the digital section and the Analog output stage. From the high-performance D/A converters to the massive toroidal-core power transformers, each element is configured for single channel processing. This prevents mutual interference effects while reproducing a rich acoustic expressiveness. In addition, the Analog audio signals of both the left and right channels are processed in full balanced mode soon after the D/A converters all the way to the output terminal, contributing to an improved S/N ratio and extended dynamic range.

This allows the fantastic sense of air that Hi-Res formats possess to be processed and conveyed without any losses.

High-quality wireless audio streaming via Bluetooth®

In addition to conventional SBC and AAC codecs, the UD-505-X also supports LDAC™ (24bit/96kHz Hi-Res audio transmission), and Qualcomm® aptX™ HD, a codec that uses 24bit/48kHz format transmission. These allow you to playback playlists on your smartphone and tablet wirelessly.

Dual onboard clocks for 44.1kHz and 48kHz, and an external clock input

Instead of referencing to an unstable and noisy PC clock during USB audio playback, a more accurate and on-board clock is generated by a high-precision, low phase-noise, audio-grade crystal oscillator for USB asynchronous transfer mode. The UD-505-X accommodates two on-board clocks exclusively for 44.1kHz and 48kHz sampling frequencies and applies the appropriate one to incoming digital signals - those that are multiples of 44.1k or 48k - to reproduce identical sound to the original by eliminating jitter effects on the audio signal.


In addition, an external 10MHz clock input is also provided, to synchronize with an even higher-precision master clock generator, such as the TEAC CG-10M/CG-10M-A, for yet further upgraded audio playback with excellent sound quality.

Up-conversion up to 384kHz/32bit PCM and 24.5MHz DSD

Employing RDOT-NEO (Refined Digital Output Technology NEO), a fluency algorithm that renders digital audio signals smoothly, the UD-505-X up-converts PCM digital signals up to 384kHz/32bit PCM and 24.5MHz DSD. With the up-conversion function activated, you will hear an improvement in quality, even with music that you are familiar with.

"Bulk Pet" USB transfer technology for enhanced audio quality

When transferring large volumes of digital data for Hi-Res audio sources through USB cables using conventional isochronous transfer mode, large variations can occur in the processing loads of the sending computer and the receiving USB DAC.


This can cause sound to drop out and other problems to occur. However, with our new USB transmission technology – dubbed "Bulk Pet" – a fixed amount of data is transmitted constantly, levelling out the processing burden on both devices and contributing to stable data transmission.

Changing the processing burden on the computer directly affects audio quality so users can select the setting they prefer (from four transmission modes).

Seven types of PCM digital filter

Seven types of PCM digital filters are available in this model. This allows you to choose the best filter according to the input file format and music style. Since the filter can be changed with a single operation of the included remote control, you can easily enjoy the differences in the subtle sound nuances of each filter type. The unit can also be used with no enabled filters.

Dual high-capacity toroidal-core power transformers

The dual monaural theme continues. Two over-sized high-capacity toroidal-core power transformers are employed in the UD-505-X, supplying stable, individual current sources for each of the left and right channels. This means neither channel will be affected by changes in the power consumption of the other during digital processing.

Improved TEAC-HCLD2 enhanced-current output buffer amp circuit

We employed the TEAC-HCLD 2 for the analog output circuit. This is a further improved version of the TEAC-HCLD circuit enhanced-current output buffer amp that increases crucial current output capacity (HCLD: High Current Line Driver). This model now uses line buffer ICs with extremely high current output capacity. 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.

TEAC-QVCS four-circuit-structure high-precision volume control newly incorporated for preamp circuits

TEAC-QVCS (Quad Volume Control System) is used for the volume circuit. This electronic volume control is a variable gain amp type comprised of four discrete circuits for left, right, positive and negative (L+, L−, R+, R−). By placing the variable gain amp volume control, which processes in analog, in the audio signal path on the circuit board, issues with noise resulting from diverging wiring are avoided.

Furthermore, this TEAC-QVCS enables volume adjustment in 0.5dB increments, allowing you to set the perfect volume for your audio system or headphones.
