Violectric HPA V550 / V550 PRO Premium Balanced Headphone Amplifier + Preamp

HPA V550 Premium Balanced Headphone Amplifier + Preamplifier, by Violectric.

Also available is the HPA V550 PRO model, which is identical except for the inclusion of a 256-step relay attenuation volume control, maximising the performance for ultimate volume control and even lower noise floor.

The Violectric HPA V550 is pure analogue functionality, delivering perfect driving of any dynamic headphone plus an outstanding pre-amplifier function.

The latest findings from the multiple test winners from Violectric and Niimbus were implemented in this headphone amplifier. All functions can be conveniently controlled using a stylish IR remote. With its incomparable technology, HPA V550 not only offers one of the most powerful headphone amplifiers in the market, but also:

LOWEST NOISE through a very small amount of internal gain. This makes the amplifier's self-generated noise inaudible.

HIGH OUTPUT VOLTAGE through 50 V internal operating voltage. Therefore ideally suited for high-impedance headphones deserving high output voltage swing.

HIGH OUTPUT POWER thanks to powerful amplifiers that offer far more power even the most demanding headphones would need and best suited for headphones with low impedances as well as Planar headphones.

HIGH DAMPING FACTOR due to lowest output impedance and therefore the ideal match for difficult to drive headphones without negative side effects and with the guarantee for a uncompromising frequency response.

Control your HPA V550 with the stylish remote control, milled from a solid piece of aluminium. Via infrared you have access to motorised volume control, mute, input selection, resampling settings, headphone and line-out control.

HPA V550 covers most features of the high-end DHA V590, except the D/A converter.
