We live in a modern world!

With the Stream Box S2 Ultra we have designed a completely new product in the streaming world. It features never seen control scenarios and unprecedented audio performance. Its main goal is to be a universal device that can get any USB DAC into the network, upgrading your favourite high-end DAC with modern and future proof streaming capabilities.

With the gaining ground of internet streaming services, such as TIDAL or Spotify, the consumer‘s interest has shifted towards network enabled devices. Many great sounding products though do not offer any network ability, either because they are too old or their main focus was not on this subject. The solution has often been to replace them with a new and modern device, stream audio via Bluetooth or to compromise and use a smartphone or tablet via their analogue output to feed active speakers or amplifiers.
There never was a really good solution for the consumer. Until now.

Stream Box S2 Ultra: the smart addition

Stream Box S2 Ultra closes the gap, it offers modern connectivity with its network inputs and USB A output. This USB output is perfection for audio signals, it uses a dedicated internal power supply and only top audiophile grade components. You won‘t run into file-support issues, as Stream Box S2 Ultra acts as a network bridge, bypassing the files directly to your digital to analogue converter. Since most DACs only have one USB input, we have designed Stream Box S2 Ultra also to be a USB detox device. Simply connect your PC to the micro USB input of the unit and connect our DAC to the audio output. This way you can clean the noisy signal of your PC, while enjoying your music with it.
Our new remote control iOS and Android App is based on an open source project and has a large community behind it. This guarantees full support and future improvements.

Stream Box S2 Ultra: feature galore!

Stream Box S2 Ultra is fully remote control able via smart devices and a regular web-browser. It offers support for the most popular streaming services: Spotify, TIDAL, Qobuz, HRA Streaming. These services offer you a sheer endless amount of music, guaranteeing you, that you never run out of music to listen to. By implementing TuneIn, we also give you the option to listen to various internet radio stations. You can listen to your favourite radio shows, the news and discover new channels from all around the world – with just a few clicks.

The back-sided HDMI video output lets you connect your monitor to the Stream Box S2 Ultra. It will then show you the graphic user interface, ready to act on your commands. With the implementation of Shairport we were even able to give the iDevice users out there another possibility to send data to our Stream Box S2 Ultra.

There are two USB inputs on Stream Box S2 Ultra, one front sided and one back sided. Both give you the possibility to connect an external hard drive to the unit. Via one of the various control scenarios (App, Web browser, external monitor) you can pick from your own selection of audio. The file system support goes up to PCM 32bit / 352.8 kHz and DSD256.

Here at Pro-Ject, we are big supporters of the Roon software, that is why we wanted the Stream Box S2 Ultra to be Roon Ready and fully certified. This way you can simply pick your Stream Box S2 Ultra in the Roon interface and send bit-perfect audio streams to it over your network.

This incredible feature set makes Stream Box S2 Ultra bullet-proof for all future events. Together with Pre Box S2 Digital they become the most versatile and audiophile set in its price class.

Fantastic Boots!
Size: 8.5, Color: Redwood/Gum 10
Completely satisfied with these boots. True to size, well made, comfortable from the get-go; not break in needed. Waterproof- really. The Red Suede has withstood a nasty winter season & still looks great. Good traction. I like the ankle height which looks good with long, mid length pants & leggings. I love the easy slip on/off aspect..made getting ready for dog walking easy. I 100%recommend!

Definitely worth the price
Size: 6.5, Color: Black/Black
Absolutely love these boots! I originally bought them to wear in NYC in December & they did not disappoint. They were comfortable, cute, durable and worked well in the slush/snow. The traction on the bottom is also nice! They kept me warm with wool socks. I wear them almost daily now. Perfect for everyday. easy to wear with variety of outfits. Good every day shoe.

Snagged a deal
Size: 7, Color: Redwood/Gum 10
I waited and waited to get these boots! I knew I was chancing it, but they went on sale, and I snagged them! I am a size 7, and they fit nicely with socks. a little loose, barefooted, but what psycho wears boots without socks? They are comfortable and really well-made.

Cute, comfortable waterproof boots (a little snug to put on)
Size: 7, Color: Velvet Tan/Gum 2
These are really cute Chelsea-style boots and feel very comfortable once they’re on. The waterproof material is great for wet weather and the sole feels sturdy with good traction. They look stylish enough to wear casually but still feel practical for rainy days. The only downside is they can be a little difficult to put on at first because the opening is somewhat snug, but once they’re on they fit well and feel supportive. Overall they’re a great waterproof boot and I’ve enjoyed wearing them.

Surprisingly great for my wide feet and high instep!
Size: 10.5, Color: Velvet Tan/Gum 2
So thrilled I took a chance on these. Finding boots is impossible for me. I have wide feet, a super high instep, a bunion on one foot, and I wear a hard to find size (10.5). I ordered the 10.5 and 11 in these expecting I might need to size up for width (if I could even get them on). It was a struggle getting the 10.5s on the first time, and once I did they were somewhat uncomfortable on the top of my left foot. But I read that they would relax so decided to give it a go because I need waterproof boots for an upcoming trip and the 11s felt too long. After two days of light wear, they are already breaking in and I have no more discomfort. Getting them on is already easier and they are plenty wide enough and very comfortable to walk in. These are true to size. Super happy and worth a day of mild discomfort to break them in!
