Pro-Ject Head Box DS2

High end headphone amplifier for the most demanding audiophiles with dual-mono design and symmetrical inputs and outputs

The HiFi headphone market is currently expanding rapidly with new models of headphones and speakers.These headphones are capable of reproducing excellent sound with a good amplifier, unfortunately the quality of most amplifiers used is only average.For example, planarmagnetic headphones require more current and simply need more power to reach their full potential.The Head Box DS2 is suitable for all headphones (even the most demanding ones) because it has a high power output of 1100 mW into 33 ?.

The Head Box DS2 headphone amplifier offers three different selectable settings to suit any type of headphone. At the same time, one of four gain settings can be selected according to the type of headphones connected to perfectly match their impedance and sensitivity.

The fully symmetrical Dual-mono design is complemented by a phase shifter that converts any unbalanced signal to symmetrical directly at the input.A 4-pin symmetrical XLR output connector on the front ensures superior signal transfer to the headphones.

A pair of highly regarded Texas Instruments TPA6120A2 chips on the power stage guarantee excellent sound with almost immeasurable noise.The two outputs on the front can be used simultaneously to share the listening experience.

Whether you are using demanding dynamic headphones, hungry planatmagnetic headphones, or even quality sensitive in-ear monitors, the Head Box DS2 adapts perfectly to all of them, ensuring a superior listening experience every time.

The sleek metal chassis is resistant to both vibration and electromagnetic interference. The Head Box DS2 is available in black or silver. A version with luxurious walnut or eucalyptus wood side panels is also available at an additional cost.
