Teac NT-503 in Black
USB DAC | Network Player
The key to a great-sounding digital audio system is the DAC. The NT-503 employs a pair of VERITA AK4490 DACs, designed by Asahi Kasei Microdevices Corporation.
The VELVET SOUND architecture on the AK4490 is capable of produce fine-detailed expression of sound even outside the human audible range to make Hi-Res Audio playback sound its best. Its newly developed Low Distortion Technology boats 112dB of S/(N+D), the highest level in the industry for a 120dB-class DAC.
In addition to 11.2MHz DSD Native playback, the NT-503 also supports a wide variety of Hi-Res Audio sources, including 32-bit/384kHz PCM. Smooth details and outstanding sense of sound placement are reproduced at the limits of Hi-Res Audio.
The NT-503 includes TEACs latest FPGA (programmable IC) with our exclusive Fluency up-conversion algorithm. In addition to the 2x, 4x, and 8x PCM up-conversion processing, DSD up-conversion is also supported as high as 12.2MHz (4x DSD). Thanks to this unique system, 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. You will experience the dense sense of air that the DSD format inherently has, even when listening to CD or MP3 from your huge music collection.
The AK4490 is a product in the Audio4pro family brand developed by Asahi Kasei Microdevices Corporation for professional audio equipment and high-end digital audio applications.
