TEAC UD-505-X
Flagship dual monaural USB DAC with an integrated fully-balanced headphone amplifier
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 ESS Technology ES9038 Q2M 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 analogue section, which is one of the keys to sound quality, includes four TEAC-HCLD buffer amp circuits process different drive modes, – fully-balanced drive for balanced output, and parallel drive mode for unbalance output, – to achieve enhanced acoustic expressive. 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.
