Teac UD-501

This TEAC UD-501 in Excellent condition,light use. The Teac UD-501 is a dual mono design and packs a lot of technological punch into its narrow, stout A4-sized aluminum-wrapped and handle-equipped body. A pair of TI/BurrBrown PCM1795 32-bit DACs take care of the D to A conversion and the USB input is of the asynchronous variety meaning it controls the all-important system clock. There are a pair of toroidal-core power transformers and twin MUSES8920 op amps for the headphone output. That volume control you see on the right side is only for the headphone output as the UD-501 does not offer variable output for its RCA or XLR pairs.
