Teac UD-501 Digital Analogue Converter – Black

A great example of this excellent small format DAC from Japanese specialist TEAC. Full working order, with original box and manual. Three months warranty.

The UD-501 supports Direct Stream Digital (DSD) playback at either 2.8 MHz or 5.6MHz (DXD) rates. PCM audio is supported up to 384kHz/32-bit resolution. It connects to your computer over USB using ASIO 2.1 or DoP.

The output section of the UD-501 features two BurrBrown 32-bit DACs per channel and JRC MUSES op amps, also with a dual monaural design. Both balanced XLR and unbalanced RCA outputs are available to connect to your power amplifier. A toroidal-core power supply ensures top performance and clean transient playback, for quality that outperforms components five times its price.
