A versatile Network Player/Dual-monoaural DAC that allows you to explore music and experience it at the highest standard of fidelity.
The NT-503 employs an identical DAC section to the UD-503DAB which is a TEAC's flagship D/A converter unit. In order to reproduce Hi-Res Audio sound on both left and right channels precisely and independently, the NT-503DAB accommodates a pair of Toroidal-core power transformers and dual DAC chipsets, and symmetrically layout output stages on the dual-monaural circuit design concept, while the "TEAC-HCLD" circuit which consists of four discrete enhanced-current buffer amplifiers settled at both positive and negative phases on both left and right channels is employed in the analog line amplifier section, and it enhances transient character and precisely renders dynamism of music.
 
The NT-503DAB also applies up-conversion to all in-coming digital audio signals, based on a fluency algorithm that processes more natural interpolates than conventional up-conversion methods. Any in-coming digital audio signals can be transformed into 12.2MHz or 384kHz PCM at maximum (maximum value may vary depends on the original digital audio data), and missing audio data higher than 20kHz are produced by analogical interpolation algorithm to restore natural sound as close as the original one.
