With its incomparable technology, the HPA V550 offers one of the most powerful headphone amplifiers on the market. Simply Brilliant: The function of the HPA V550 is limited to purely analog values, namely the headphone playback and the preamplifier function. The latest developments of the multiple test winners from Violectric and Niimbus have been implemented in the headphone amplifier. The preamp functionality has also been taken to a new level in the V550. Every function can be controlled via the remote control so that you can concentrate on listening pleasure. The HPA V550 corresponds to the test winner DHA V590 - but without a D/A converter. Overview: - Lowest noise - due to a very small internal gain. As a result, the inherent noise of the amplifiers is inaudible. - High output voltage - due to 50 volt internal operating voltage. Therefore ideally suited for high-impedance headphones. - High output power - through powerful amplifiers that can deliver far more power than even the most demanding headphone can need. Therefore ideally suited for headphones with low impedances and also magnetostatics. - High damping factor - due to the lowest output impedance. Therefore ideally suited to control even the most difficult headphones without influencing them with a guarantee for an uncompromising frequency response. - Remote Control - Control the HPA V550 remotely with its sleek, one-piece remote control. Infrared gives you access to the motorized volume control, mute, input selection, resampling settings, headphone and line-out control.
