TEAC Corporation (TOKYO: 6803) is proud to announce the release of the model UD-507, a completely redesigned 500 Series DAC/Preamp/Headphone Amplifier based on the high-end 700 Series but in a compact package. Products will be available for shipment in late June.
KEY FEATURES
Highly Musical Discrete DAC Designed and Developed In-House
The UD-507 is equipped with our proprietary โTRDD5โ (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, โThe most important feature of the UD-507 is the newly designed and manufactured โTRDD 5โ discrete D/A converter. The design goal of this in-house developed DAC is to provide a more immersive musical experience for all listeners. Thanks to its clear soundstage and precise imaging, you will discover the breadth and articulation of your favorite artists that you never noticed before.โ

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 to the UD-507.

Other Key Features
- Full-stage dual monaural/balanced circuit configuration for excellent channel separation
- 22.5MHz DSD and 384kHz/32bit PCM playback as USB DAC
- Preamplifier with 5 digital inputs: USB Type-B (rear), USB Type-C (front), Coaxial, Optical, Bluetooth) and 2 analog inputs (RCA, XLR)
