"Pro-Ject’s Pre Box S2 Digital offers a wealth of audiophile tweakery but its emphasis on USB ties it primarily – but not exclusively – to desktop and laptop PCs. On the other hand, USB hook-up means the S2 is still a portable option for laptop users, and it doesn’t need a battery. For the price, its sound performance is impeccable, combining clarity and precision with an attractive warmth and impressive sense of space." |
