Violectric HPA V550


New to the already impressive product line-up of Violectric are the HPA V550 and HPA V550 Pro headphone amplifiers. These two new models find their basis in the award winning Violectric DHA V590-2 excluding the D/A converter.

They cover the analogue functionality, the perfect driving of any dynamic headphone and the outstanding pre-amp function which can be conveniently controlled using a stylish remote. The HPA V550 Pro differs to the V550 with it’s 256 step relais attenuation volume control. Not just a feature, but a high precision attenuator that maximizes the performance of this headphone amplifier for ultimate volume control and an even lower noise-floor.

The Violectric HPA V550 (Pro) covers most features of the review winner DHA V590 – except the D/A converter. So, HPA V550 covers the analogue functionality, the perfect driving of any dynamic headphone and an outstanding pre-amp. The latest findings from the multiple test winners from Violectric and Niimbus were implemented in the headphone amplifier. All functions can be conveniently controlled using a stylish remote. With its incomparable technology, the Violectric 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. So best suited for headphones with low impedances as well as magnetostatic headphones

High Damping Factor – due to lowest output impedance. Therefore the ideal match for difficult to drive headphones without negative side effects and with the guarantee for a uncompromising frequency response.

Remote – Control the HPA V550 with its stylish remote control, milled from a solid piece of aluminum. Via infrared rays you have access to motorized volume control, mute, input selection, resampling settings, Headphone and line-out control.

The most demanding headphones can be powered with these Violectric headphone amplifiers, the 4 powerful amps output 6400 mW at 50 Ohm and 21V RMS into 600 Ohms. Due to the high damping factor and lowest output impedance these amps are an ideal match for difficult to drive headphones, without the negative side effects and guarantee for an uncompromising frequency response.
