Product Details

Sony Silver Hi-Res USB DAC System For PC Audio, Model UDA1S

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

Comments about Sony Silver Hi-Res USB DAC System For PC Audio:

Know that I'm a fan of Sony Electronics - this little box is one more reason why I am. That said, I don't consider myself either an audiophile or technophile so I was initially skeptical around "Hi-Res Audio" and whether a digital-to-analog conversion device would justify its price tag. Short answer: Yes, it is definitely worth the price. The UDA-1/B USB DAC is designed to be the heart of a computer-based digital music system. It can power a pair of quality bookshelf/desktop speakers or it can drive high-end headphones. Naturally those devices need to be of sufficient quality before you can appreciate what this Hi-Res Audio amplifier will supply. I discovered that high-resolution audio really does sound better even to my over-60 ears, or should I say, especially with my compromised hearing. As soon as I set up the UDA-1/B with a pair of Sony SS-CS5 Bookshelf speakers (3-way, 3-driver, bass reflex), my music files seem to burst out with tone and texture. Over time I had forgotten how fine the original recordings ought to sound. And, the combination of the DAC with these particular speakers works nicely in both sound quality and level (the 20+watts per channel can fill our good-sized living room). I particularly like to listen to cello solos and cello with full orchestra. It was a revelation to hear pieces that I am very familiar with sounding so clear and, well, exciting! I've only had the UDA-1/B for a short time and already find I am listening more often and enjoying what I can hear now. The very first track I tried, YoYo Ma playing the first movement of Elgar's Cello Concerto (Chicago Symphony), convinced me. But you'll need to hear your own music to agree. After the Elgar, I decided to throw additional tracks at the UDA-1/B to see how it handles different musical situations. First, the second movement of Charles Ives' Symphony No. 4 (Chicago Symphony), where the music builds to several riotous climaxes. I could hear detail and separation that surprised me given the complexity of Ives' compositions. Not everything I listen to is classical though. Next I switched genres to a live digital recording of T-Bone Walker's "Stormy Monday" by Hummingbird (a band from Connecticut's Northwest Corner that plays an eclectic blend of blues, jazz, and country). It pleased me to recognize the acoustic ambiance of Miranda Vineyard's club-like tasting room behind Bobbi Soares' melodic, jazz-influenced voice - nicely resolved by the UDA-1/B's Digital Sound Enhancement Engine. Finally, to represent another slice of my listening time, I wanted a close mic'd track without instrumental distraction. I chose the title track of singer-songwriter Shane Faubert's new "Line in the Sand" album on the French Bam Balam label. It's a non-compressed Folk/Pop recording with a lot of air around his smooth, buttery-voiced and intimate vocals. I turned Off the DSEE for this one and, again, the UDA-1/B and SS-CS5 combination performed with a presence that felt as if the artist was in the room. Very nice. What I didn't anticipate is that the performance of my vintage Challenger headphones by Superex falls short, way short. [Told you I wasn't an audiophile - in case my wife is reading this, I'm putting a pair of Sony's MDR-1A/B stereo headphones on my holiday Wish List.] For convenience, I have been using my Xperia Tablet Z attached to the UDA-1/B's front-panel USB port and playing tracks from the Walkman app (8.5.A.0.6, Android) with ClearAudio+ turned On and DSEE set On at the DAC. There is a handy Remote Controller (small at 3-3/8" long) that can: turn the unit On/Off; Volume +/-; Muting; Switch among the five inputs (USB Front Type A, USB Rear Type B, Coaxial, Optical and Line); as well as DSEE On/Off. There is a really easy-to-read Help Guide for the UDA-1/B, that I strongly recommend studying, at: For example, I learned the audio formats that the UDA-1/B can decode depend on which digital audio input jacks you use to connect. Also, I found out there is a Protector Function that kicks in when an abnormal current is output to the speaker terminals, or when the internal temperature of the UDA-1/B is too high - all the input indicator lamps flash for 5 seconds and the unit turns off automatically. Good to know. I am a MacBook Pro user. So, for a connection with my laptop, I downloaded and installed a free app called Hi-Res Audio Player and a driver named SONY USB DAC Amp Driver (Mac). It's easy to do and it's all explained in the Help Guide. The Player launches from the Desktop, finds the UDA-1/B, and presents a straight-forward playlist interface (see screenshot below). Those are .aiff files on a 400Mb Audio CD, the cable is the included USB A-B to the DAC's rear panel. Like most of Sony's home audio products, the UDA-1/B has a clean, pleasing design that is quite functional. I have the black model and there is also one in silver. If I had Sony Engineering's ear I'd suggest it would be helpful to visualize the volume level setting, especially when using the Remote Controller. You will need to provide speaker wiring (don't skimp) and compatible speakers that have the ability to reproduce the fine audio this unit is capable of delivering. Sony does include an A-B USB cable (rear panel). Summing up, I am more than satisfied with my UDA-1/B set up as described, however over time I expect to add additional sound file sources and find more creative ways to enjoy this fine component. I recommend it without hesitation.
