TEAC UD-507 USB DAC/Headphone Amplifier/Preamp - TEAC
Completely redesigned 500 Series DAC/Preamp/Headphone amplifier with high-end 700 Series design concept in a compact A4-size package.
The UD-507 is equipped with TEAC’s proprietary “TRDD 5” discrete DAC, designed with musicality as the top priority. Following in the footsteps of TEAC's acclaimed 701 series, the new “TRDD 5” discrete DAC offers a clear soundstage and accurate imaging, providing listeners with a truly immersive musical experience.
Fully Balanced Dual Monaural Headphone Amplifier
The UD-507 is a headphone amplifier featuring the TEAC-HCLD2 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 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.
