Bought this streamer to pair with Project DAC and connect as a Roon endpoint. I was using a Mac previously, however after once connecting this unit and using the clean USB port for the DAC, the difference is ‘chalk cheese’. The mid range has grown and the space perception has increased, individual instruments are clear. I have been using my valve amp for many years but it has never sound this good. Worth every cent.

Most of the music streamers out there are big boxes, with a price tag to match. I won't mention names, but many of the popular sellers left me flat so:nically.Then I read John Atkinson's highly positive review of the S2 Stream box ultra in Stereophile. This little box works exactly as John described and sounds way above its price point. My only quibble is that I find the web interface and phone app a little clunky. But they get the job done, and you get used to them. I now stream a lot of high definition files from Qobuz and my own ripped CDs on a USB hard drive. It all sounds superb. Highly recommended.

Good streamer but app needs improvement
