Analogue and streaming done right

The Uni Box S3 dares to break away from the norm, redefining what a modern streaming amplifier can be. While many amplifiers are dominated by deeply integrated streaming tech – compromising their core design – the Uni Box S3 takes a different path.

The Master of Analogue & Digital

The Uni Box S3 masterfully bridges the worlds of analogue and streaming. Your analogue sources - like turntables - are not digitised, preserving their rich and lifelike sonic character. With a fully analogue pre- & and power amp design, every nuance of your music is delivered with breathtaking punch and dynamic precision. At Pro-Ject Audio Systems, our mastery of analogue hardware design allows us to craft an astonishingly powerful amplifier within the sleek, compact aluminium case of the Uni Box S3. All this power remains usable entirely without a mobile app or the need to constantly update software.

Market leading streaming

Partnering with WiiM, the Uni Box S3 streaming technology is powered by the industry leading WiiM OS™. The Cirrus Logic CS4344 DAC offers a high quality resolution of up to 24bit and 192kHz.

With the Pro-Ject Home app you control the streaming options on input 8 - the streaming input. Setting up the WiFi connection is a breeze. Just open the app and it automatically detects your new Uni Box S3 and walks you through the setup process. Comfortably reset the WiFi connection via long press of the Stream button on the front panel.

Fun puzzles, cliffhanger ending
Format: Kindle
If you’ve read the earlier books about the Hawthornes, you know that Avery Grambs, the heiress to the Hawthorne fortune, established an annual game of puzzles and riddle in which the winner would win a whole lot of money. This book is about one of those games. I finished this book late last night, and the first thing you need to know is that it ends in the middle of the game! Barnes calls this a new series, and obviously, it’s the kind of series in which books are tightly linked. The next book comes out next July. So forewarned. I found I had to concentrate at the book’s start because there’s a lot to sort out. There are 8 players, mostly new characters Hawthornes there, mostly in background with Grayson having a bigger role. There are also three points of view. So it took me quite a while to be sure I knew who was who and what their backstory was. I’m not actually sure I understand all of them even now, partly because Barnes withholds some information for the next book Still, page by page, I enjoyed this book. I liked solving the puzzles and was pleased with myself when I did it faster than the characters did though that wasn’t as often as I’d like. The books takes place over 2 days, I think, but there’s some insta-attraction I guess, which is interesting. The ending was unsatisfactory for me, and Barnes obviously intended it to be that way. I’ll undoubtedly pick up the second book next year, but I’ll have to reread this one to have any hope of following it.
