Pro-Ject has launched two new headphone amplifiers, the Head Box DS3 B and the Head Box S3 B, marking the debut of a new generation of fully balanced amps.
Being fully balanced means that not only do these amplifiers feature balanced connectors for headphones, but the entire audio path is balanced as well. This design minimizes noise and enhances stereo separation, resulting in cleaner, more detailed, and spacious sound.
These amplifiers are compatible with unbalanced headphones and include line-level inputs with RCA and XLR connections for seamless integration with other devices.
