Key Features
The TEAC UD-505 is a flagship dual monaural USB DAC with an integrated fully-balanced headphone amplifier, that fuses high-end audio design concepts and TEAC’s decades of audio design experience, in an A4-sized footprint.
Like its predecessor models, the UD-501 and UD-503, it employs a dual monaural circuit design to process audio signals with even greater purity, with the latest VERITA AK4497 DAC chip used on each of the two channels. This improves the S/N (signal to noise) ratio by processing each channel individually in monaural mode, as well as delivering DSD512 (22.5MHz) native and 768kHz/32-bit PCM playback capabilities.

The headphone section is remarkable. A totally new 4.4mm headphone jack, called Pentaconn, is employed, allowing balanced and active ground connections within a single jack, while conventional 1/4” phone jacks are also provided. In addition to a wide range of digital and analogue inputs, a Bluetooth® receiver supporting LDAC™ and Qualcomm® aptX HD™ allows you to enjoy high-quality wireless audio streaming from your smartphone on this flagship USB DAC.
The UD-505 is a compact and high-spec USB DAC and headphone amplifier that supports today’s high sampling rate Hi-Res formats.
