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 TEACs 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.
