Description

Teac UD503

  • USB DAC that supports 11.2MHz DSD and 384kHz/32-bit PCM
  • Dual-monaural circuit structure used from the power supply to the digital and analog sections
  • Both left and right channels have their own high-end AK4490 DACs, which are made by Asahi Kasei Microdevices Corporation
  • Two high-capacity toroidal core power transformers—one each for left and right channels
  • Isolation circuit that completely separates the digital and analog sections electrically
  • 4 TEAC HCLD buffer amplifiers, which are current-enhancing output buffer circuits, are used for the line amplifiers
  • Up-conversion to formats up to 12.2MHz DSD and 384kHz/32-bit PCM using an FPGA (programmable IC) that utilizes a fluency function
  • One pair of RCA analog unbalanced inputs
    OELD display shows input signal type and various settings (with 3-level dimmer and off functions)
  • Fully-balanced drive headphone amplifier with discrete construction and maximum output of 700 mW + 700 mW
  • Headphone amplifier can be switched among 3 drive types: unbalanced, balanced and active ground
  • Digital inputs on the back include one USB, one coaxial and one optical
    Combined coaxial mini/optical mini digital input connector on front is convenient for digital input from portable devices

The UD-503 have received Japan’s most authoritative award, the VGP 2016 (Visual Grand Prix) Gold Prize in D/C Converter category in October 2015.
