TEAC NT-503 USB DAC & Network Player

The Center of Your Digital Audio System

The 2016 winner of Japan’s prestigious Visual Grand Prix award in the “Network Audio” category, the TEAC NT-503 is a versatile network player with a dual-monaural USB DAC. It can play digital audio files from a variety of sources: a computer using a USB port, a network server using an ethernet port, or a USB storage device. Based around a dual-monaural design and the TEAC-HCLD circuit, the high-quality analog output circuit creates the ideal preamplifier unit, delivering both balanced and unbalanced audio signals. The NT-503 is similar in design to the company’s well-regarded UD-503, but replaces one of the latter’s two 6.35-millimeter headphone jacks with a front USB port for reading audio files from a USB storage device. Finally, the OLED display has a four-level dimmer with high contrast and great visibility.
