Pro-Ject Head Box DS2 B Silver - balanced headphone amplifier with plenty of headroom

Pro-Ject Head Box DS2 B Silver is a fully balanced headphone amplifier for those who want more control, dynamics, and detail from their headphones. It is developed for both sensitive models and more demanding headphones that need extra power.

What we especially find makes the Head Box DS2 B interesting is its flexibility. With four gain settings, three power settings, and both a standard and balanced headphone output, you can adapt the amplifier to your specific headphones. That also makes it an interesting solution if you want to upgrade later.

Adapt the Head Box DS2 B to your headphones

Not all headphones need the same amplification. Some are easy to drive, while others require more power to perform at their best.

This is where the Head Box DS2 B is particularly interesting. The four gain settings and three power settings make it possible to adapt the amplifier to everything from sensitive in-ear models to more demanding over-ear headphones.

With an output power of 2 × 550 mW at 33 ohms, you also get an amplifier with a solid power surplus.

Balanced construction and flexible connections

Head Box DS2 B is built with a fully balanced dual mono construction, where the right and left channels have separate signal paths. This limits unwanted interference between the channels and provides good conditions for precise stereo reproduction.

You get both RCA and XLR inputs as well as a built-in phase inverter that can convert an unbalanced signal into a balanced signal internally in the amplifier.

On the front, you will find both a 6.3 mm jack and a balanced 4-pin XLR. Both outputs can be used at the same time, so two of you can share the music experience.

Well-thought-out details and elegant design

Pro-Ject has chosen two TPA6120A2 amplifier chips from Texas Instruments and a BLUE ALPS volume control. These are well-considered component choices with a focus on precise amplification and comfortable operation.

The solid aluminum cabinet in silver fits beautifully into a serious hi-fi system. If you want a more classic look, wood side panels can be added as an optional extra.

For us, the Head Box DS2 B Silver is a strong choice for those who want a dedicated headphone amplifier with balanced connections and the ability to tailor the sound to your equipment.
