Teac NT-503
USB DAC Network Player, Black


The TEAC NT-503B is a versatile network player with premium-quality dual-monaural USB DAC. The NT-503 employs a pair of VERITA AK4490 DACs. The NT-503 also supports a wide variety of Hi-Res Audio sources, including 32-bit / 384 kHz PCM. Smooth details and outstanding sense of sound placement are reproduced at the limits of Hi-Res Audio. The NT-503 up-converts 16-bit/44.1kHz data from a conventional CD into 11.2MHz DSD – over 256 times the data. Audio data higher than 20kHz is produced by an analogical interpolation algorithm to restore natural sound as close as the original one.
