The UD-503 is the successor to the UD-501 and still features dual-mono architecture and a high quality headphone amp with balanced/unbalanced outputs.
Under the hood you’ll find twin AKM Verita AK4490 DACs which support up to 11.2MHz DSD and 32-bit/394kHz PCM files. A fully asynchronous USB transfer mode allows the DAC to control and sync incoming PCM and DSD audio signals using the built-in 44.1kHz and 48kHz clocks. An optional external 10MHz master clock can be added for greater precision.
The company’s own High Current Line Driver (HCLD) circuit not only supports single-ended headphone output, but balanced and Active GND modes too.
The TEAC UD-503 is available now in black or silver for £700.
The NT-503DAB meanwhile not only supports high-res audio over USB, but also high-res streaming over a network. DSD 5.6MHz and 24-bit/192kHz WAV/FLAC files can be played back from a PC or NAS drive.
The NT-503DAB has built-in DAB/DAB+ radio support, as well as Spotify, Deezer, TuneIn radio portal and aptX Bluetooth.
Finally, a single-headphone output benefits from TEAC’s HCLD (High Current Line Driver) circuit to “deliver mostly Class-A performance for single-ended headphones of up to 600ohms”.
The TEAC NT-503DAB will be available at the end of November in black or silver, priced £950.
