REVIEW & AWARDS

Test Mini-HiFi: Pro-Ject Pre Box S2 Digital and Amp Box S3 – Honey, I shrunk the amplifiers - Read More

"Not only from a sonic point of view but also because of the flexibility gained when upgrading/replacing individual components, making things more sustainable."

 

Test: Pro-Ject Pre Box S2 Digital and Amp Box S3: how small can HiFi be? - Read More

"It works! And much better than you would expect from these cute little devices. The Pro-Ject Pre Box Digital is a serious DAC and preamplifier for the most important digital sources, plus a headphone connection. And the Amp Box S3 stereo power amplifier is a no less impressive power amplifier in "nano format" with great sound capabilities for connection to a huge selection of passive speakers.

If you are looking for an affordable and truly space-saving audio component solution, you can hardly ignore the Pro-Ject S2/S3 series. The combination options are huge, but you are spoiled for choice. The two test candidates are an ideal team for desktop hi-fi, to upgrade the media center in the living room, or as a second system in other rooms." - Frank Borowski
