As part of Sony’s high resolution audio push, a number of fairly unique products have been released, not least of which is the rather diminutive Sony UDA-1 Integrated Amplifier with inbuilt DAC, the perfect partner to any audiophile’s desktop system, or is it more than that?
The Sony UDA-1 is small, there is no getting away from that, at only 225mm wide and 74mm tall it easily fits on a desk to power a decent pair of speakers. The USB DAC input handles 24bit/192kHz PCM signals via the optical or coaxial inputs as well as DSD streaming via the USB input.
That is unusual for a simple little desktop amp, but this really is more deserving of placement anywhere you need great sound quality, be it your desktop or your living room, if your speakers are very efficient or you do not require house party levels of volume from it.
I have tried this amp on the desktop driving a pair of Dali Ikon 1 Mk2’s very nicely, at levels above what is needed in that situation to be honest. I have also used it in the living room with a pair of Studio Electric Monitors that are not the last word in efficiency, but it drives them rather well, if not very loudly.
It has to be said, the DAC in the Sony UDA-1 is very bloody good! I use Roon as my playback app and have tried it straight out at native resolutions as well as up sampling everything to DSD128 and it is fabulous. There is a fan in the rear of the unit but I have never heard it, even after having it on for several hours.
The headphone socket for those inclined to more personal listening, is also above standard I would say. Driving my Fostex TH900’s was not a problem and sounded excellent. All in all, a thoroughly enjoyable amp/DAC combo.

Why you want the Sony UDA-1:
If you are after a high resolution playback system for your desktop or small room, I can not recommend the Sony UDA-1 enough. The DAC is excellent, the amplifier is excellent, it is built like a tank, and runs for several hours at a time without ever getting too hot or too noisy. It just keeps delivering great sound quality, and is that not the whole idea?
