Reviews
“An alternative very much worth considering”
Germany, 12.2022
• Not only from a sonic point of view but also because of the flexibility gained when upgrading/replacing individual components, making things more sustainable.
“An astounding amount of performance from the most compact case“
Germany,11.2022
• The Pro-Ject Pre Box Digital is a serious DAC and preamp for the most important digital sources, plus a headphone jack. And the Amp Box S3 stereo power amplifier is a no less impressive „nano-sized“ power amplifier.
“I am very happy to recommend it!”
Hungary, 03.2024
• Delicious, relaxed and neat detailing.
• The stage is open and airy, and the sound quality is outstandingly good considering the price. Bass is nice, shockingly hitting a lot in some places.
• Mids and highs are astonishingly natural and clean.
