Product Details

Sony Black Hi-Res USB DAC System For PC Audio, Model UDA1B

Experience Hi-Res Audio in an easy solution with the USB DAC and Amplifier that connects to your PC, supports DSD and the full range of Hi-Res file formats and is compatible with any music player like iTunes, Windows Media player and more.


  • Hi-Res formats supported
    The UDA-1 can decode the following file formats: DSD (DSF,DSDIFF), PCM(44.1k/ 48k/ 88.2k/ 96k/ 176.4k/ 192kHz·16/ 24/ 32bit) DSD(2.8/ 5.6MHz), WAV, AIFF, FLAC, ALAC, ATRAC Advanced Lossless, ATRAC, MP3, AAC, WMA music file playback
  • Music Playback
    Connect the UDA-1 to a PC via USB and use any music player like iTunes, Windows Media player, Media Go and more to enjoy the hi-res music experience
  • Analog FIR Filters
    This digital-to-analog converter effectively reduces high-frequency noise in DSD signals. It features independent right and left channels, with four analog FIR (Finite Impulse Response) filters per channel producing a combined one-clock delay. FIR filters are ideal for D/A conversion of DSD signals
  • Digital Sound Enhancement Engine (DSEE)
    When turned on, the DSEE offers natural sound with a spacious feel by restoring high frequency sound and the tail shape of the waveform likely to be removed through the audio compression process
  • Connectivity
    Take advantage of the UDA-1 enhanced music capabilities connecting to the units’ USB (USB-A and USB-B), analog and digital inputs. The USB inputs are compatible with both iOS and Android devices. Inputs are also included for optical, coaxial and analog devices. An analog output and headphone jack are available as well
  • Large Power Source Block Capacitor
    This acoustically tuned, custom block capacitor features not only improved electrolytic solution and electrode foil magnification, but also superior case form, sleeve material and length. Only Sony utilizes this component, which is optimally tuned with chemical capacitor length and sleeve cut
  • Left-right separated, large bandwidth power amp
    This AB-class analog amp utilizes an EBT (emitter balance transistor) with a cutoff frequency of over 300MHz for the final transistor. The amp device features minimal phase variation up to the high range and excellent transient response. Its twin mono format with separate left and right channels eliminates left-right sound interference and ensures clear, high-quality sound reproduction. The resilient high range reproduces sound with rich musicality and a high degree of faithfulness
  • High-Rigidity Chassis structure
    Its all-in-one compact size and sturdy 3mm-thick solid aluminum design extends from front panel to top panel
  • One-point ground structure
    Concentrating audio signal control points into a single point eliminates fluctuation of left- and right-channel, and contributes to dynamic sound
