TEAC UD-505 silver

Like its predecessors, the UD-501 and UD-503 models, it uses a dual monaural circuit to process audio signals with even greater purity, with the latest VERITA AK4497 DAC chip used on each of the two channels. This improves the S/N (signal-to-noise) ratio by processing each channel individually in monaural mode and offering native DSD512 (22.5 MHz) and 768 kHz / 32-bit PCM playback capabilities. The analog section, which is one of the keys to sound quality, includes four TEAC-HCLD buffer amp circuits.
