The UD-505-X is a class-leading 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. The dual mono structure processes
stereo signals with higher purity, and the D/A converter section uses
one ESS Technology ES9038 Q2M in each of the left and right channels.

This model achieves a high signal-to-noise ratio by using each DAC in mono mode.
Moreover, we upgraded it with high specifications that enable native playback of
22.5MHz DSD and 768kHz/32bit PCM formats. In the analog processing section, which can be considered the key to audio quality, we include four TEAC-HCLD2 circuits. These are improved versions of our previous TEAC-HCLD. For headphone output using the newly-adopted diamond buffer circuit,
in addition to two standard 6.3mm connectors, one 4.4mm 5-pole headphone connector is available, enabling balanced connection and active ground connection with a single plug.

The Bluetooth® receiver supporting LDAC and Qualcomm® aptX HD allows you to enjoy
high-quality wireless audio streaming from your smartphone on this reference USB DAC.
