Violectric Flagship DAC and Headphone Amplifier – DHA-V590

The DHA V590 headphone amplifier is Violectric’s latest flagship offering and is a true behemoth. Since I was first introduced to Violectric back in 2015 I have always had a soft spot for their headphone amplifiers. Their low noise and insane power was something that I had never heard from any other product and I was immediately in love with their sonic performance.

The DHA V590 is a culmination of years of research and development and technology originally used in their Niimbus headphone amplifier to produce a best in class all-in-one headphone amplifier and DAC solution. It provides advanced digital to analogue conversion processing using dual DACs and 32 Bit resampling/reclocking.

It took 2 years of Audio Concierge trading before we could confidently add a headphone amplifier of this caliber to our portfolio which covers all bases with exceptional quality. The DHA V590 can be integrated into pretty much any solution. With it’s multiple digital inputs, headphone output and also analogue outputs it can be used as a high quality pre-amplifier using either the balanced XLR or line level RCA outputs. The inputs and outputs can all be gain controlled to best suit the system that it is being introduced to.

With more and more clients switching from a commutable, portable audio solution and moving towards a more fixed setup, the DHA V590 presents one of the best headphone amplifiers for your headphones and earphones. With the exceptional high output voltage it is more than capable of getting the best from your high impedance headphones and has super high output power for very low impedance headphones too such as magnetostatic headphones. The high damping also means that difficult to drive headphones remain as unaffected as possible from variance in frequency response.

For complete comfort, the Violectric DHA V590 comes with a feature remote control able to change the input, volume, resampling, output and mute.

The DHA V590 offers:
– Remote control for input selection, resampling, volume, output and mute
– 3 x analogue stereo inputs, 2 x unbalanced via RCA, 1 x balanced via XLR
– 4 digital inputs, balanced, coaxial, optical with 24 bit and 192 kHz capability,
