TEAC Introduces the UD-507, a Completely Redesigned 500 Series DAC/Preamp/Headphone Amplifier

May 2024 – TEAC Corporation (TOKYO: 6803) is proud to announce the release of the model UD-507, a completely redesigned 500 Series DAC/Preamp/Headphone Amplifier with high-end 700 Series design concept in a compact A4 size package. Products will be available for shipment in late June.

The UD-507 is equipped with our proprietary “TRDD5” (TEAC Reference Discrete DAC), which was designed with musicality as the top priority, following in the footsteps of the discrete DAC design applied to the acclaimed 701 series. TEAC Brand Manager, Jo Yoshida states, “The most important feature of the UD-507 is the newly designed and manufactured “TRDD 5” discrete D/A converter. The design goal of this in-house developed discrete DAC is to provide a more immersive musical experience for all listeners. Thanks to the clear soundstage and precise imaging, you will discover the breath and articulation of your favorite artists that you never noticed before.”

​Fully Balanced Dual Monaural Headphone Amplifier

​The UD-507 is a headphone amplifier featuring the TEAC-HCLD2 (TEAC High Current Line Driver), which is characterized by its high current supply capability. Compared to the previous model, the maximum output power has been greatly improved by strengthening the power supply, resulting in a generous driving power of 1,200mW + 1,200mW (balanced output at 100 ohm load), which is comparable to a dedicated headphone amplifier without DAC. The power amplifier gain can be switched between 3 positions (Low/Mid/High) to fine-tune the output to best match the sensitivity and impedance of the headphones.

High-Quality Preamplifier with Multiple Analog/Digital Inputs

​The UD-507 incorporates the TEAC-QVCS (Quad Volume Control System) high precision analog volume attenuator and the powerful TEAC-HCLD2 high current line buffer circuit. With five digital inputs and two analog inputs (unbalanced and balanced), a wide variety of devices can be connected.
