The DHA V590 PRO (aka DHA V5902 PRO) is the top Headphone Amplifier / DAC in the Violectric range.

Also available is the standard DHA V590 model, which is identical to the PRO version, but without the high-performance, low-noise 256-step relay attenuation volume control.

Delivered from the factory with the 256-step relay volume control, the DHA V590 PRO offers a state-of-the-art D/A converter and a headphone amplifier in one unit. The D/A converter is a new development and includes a 32-bit resampler / reclocker plus two 32-bit D/A converters per-channel.

The latest findings from multiple test winners were implemented in this headphone amplifier. Most functions can be conveniently controlled using the stylish remote (supplied). With its incomparable technology, DHA V590 PRO 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 planar 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.

The headphone outputs and / or the line outputs can be activated / deactivated by buttons on the front or by remote control. Connect not only your headphones to the DHA V590 PRO but also your power amplifier or your active speakers and enjoy this compact, fantastic sounding headphone amplifier with state-of-the-art DAC and preamplifier.

The stylish remote control, milled from a solid piece of aluminium, gives access to motorised volume control, mute, input selection, resampling settings, headphone and line-out control.
