Violectric DHA V590²
Premium headphone amplifier with internal state-of-the-art D/A converter
The Violectric DHA V590² is a powerful monitoring combination of headphone amplifier, D/A converter and preamplifier. Digital audio signals are fed in via XLR, RCA, USB or optical input, translated into the analog world by ESS-Tech ES9026 PRO converters and played out on up to three different headphones. Formats up to 384 kHz and DoP can be converted. Elegant ALPS controls regulate the volume and balance.
The pre-gain circuit adjusts the level to the impedance of the headphones being used. The carefully selected components are installed by hand in a high-quality housing with a wide range of connection options. The Violectric DHA V590² is therefore perfectly suited as the central element of a home audio system.
An included remote control offers maximum ease of use.

Balanced headphone outputs
When listening to music via loudspeakers, you are part of the auditorium. When listening via “normal” headphones, you take the place of the conductor. When listening with “balanced” headphones, you are part of the orchestra.
If headphones are operated symmetrically, the channel separation is increased even further. Balanced headphones usually have a 4-pin XLR connection or a Pentaconn plug. True balanced operation requires a great deal of effort in the form of four built-in power amplifiers.
PRE-GAIN
The headphone amplifier is positioned between the music source and the headphones. The source can be of varying power and the headphones of varying sensitivity. The Lake People PRE-GAIN serves to compensate for these differences and to optimize the headphone amplifier for every conceivable combination. This results in minimal noise, the lowest distortion factor and the best channel balance.
The PRE-GAIN adjustment is located on the rear of the Violectric HPA V340 and can be set individually in 7 stages (-18, -12, -6, 0, +6, +12, +18 dB)
Perfect headphone protection
Various circuits protect the headphones from unclear operating states, DC voltage, excessive operating temperature and overload:
Delayed ON, Instant OFF
Every headphone amplifier causes interference when it is switched on and off. This interference can damage the connected headphones. The headphones are connected to the amplifier with a delay via relays and the associated electronics and disconnected again immediately after switching off. In this way, the headphones themselves are protected from the device electronics as long as no clearly defined conditions are to be expected.
DC monitoring
The outputs are monitored for harmful DC voltage. As soon as a predefined value is exceeded, the headphones are switched off.
Overload monitoring
The power consumption is constantly measured during operation. If predefined parameters are exceeded, the headphones are switched off.
Remote control
Control the Violectric DHA V590² remotely with its beautifully designed remote control milled from a solid piece of metal. Infrared gives you access to the most important functions of the device:
- Volume
- Mute
- Input selection (XLR / RCA1 / RCA2)
- Output selection (headphones / LineOut)
Violectric's unique technology
- Lowest noise - thanks to very low internal amplification. This means that the amplifier's own noise is inaudible.
- High output voltage - due to an internal 50 volt operating voltage. Therefore ideally suited for high-impedance headphones.
- High output power - thanks to powerful amplifiers that can deliver far more power than even the most demanding headphones require. Therefore ideally suited for headphones with low impedances and magnetostats.
- High damping factor - due to the lowest output impedance. Therefore ideally suited to drive even the most difficult headphones without interference. The advantage for an uncompromising frequency response.

Violectric DHA V590² — precision balanced DAC/headamp
The Violectric DHA V590² is a consummate all‑in‑one preamplifier, DAC and headphone amplifier built for critical listening. As noted by Yung Lie of Alpha Audio, its AKM-based conversion and dedicated resampling/reclocking deliver an analogue-like, subtly warm presentation with controlled treble and impressive clarity. The unit’s true-balanced topology, Talema power supplies and separated analog/digital rails underpin a very low noise floor and strong dynamics, while a 256‑step reed‑relay volume gives precise level control. I/O includes balanced XLR, single‑ended RCA, AES, S/PDIF, optical and Amanero USB for flexible system integration. With pro-grade build and measurement-aware design, the DHA V590² suits demanding desktop and two-channel systems where transparency, silence and refined timbral character are priorities — a compelling choice for audiophiles seeking a refined integrated solution.
Pros
- Robust, pro-grade build with quality power engineering (heavy case, Talema power supplies, separate analog/digital rails) that supports long-term reliability and low noise.
- Very low noise floor and jitter control thanks to resampling/reclocking and dedicated clocking — well suited for sensitive headphones and critical listening.
- Feature-rich, high-resolution implementation: AKM-based DAC, Amanero USB input, multiple digital/analog I/O and a 256-step reed-relay volume for precise, true-balanced operation.
Sound Quality
89/100
The review discusses the company's attention to dynamic range and low THD (mentions AKM SRC 4137 theoretical specs) and explains design choices to maximize dynamic performance in an integrated DAC/amp. While Violectric opted for the AK4490 for its analog-like qualities, the text implies very good transient and macro/micro-dynamics though not claiming reference-class headroom.
Noise Floor
90/100
Design details (separate analog/digital supplies, Talema power cubes, clean power rails, reed-relay 256-step volume control and explicit resampling/reclocking to avoid jitter/hf hiss) indicate a very low noise floor suitable for sensitive IEMs. The review does not use literal phrases like 'dead quiet' but strongly emphasizes measures taken to eliminate hiss and jitter, justifying a near-top noise-floor score.
Headphone Compatibility
87/100
The amp uses a true-balanced transistor topology ('4x 8 Transistors (true balanced)'), which supports balanced operation and robust drive for a wide range of headphones. The review does not publish explicit output impedance or power figures or list measured performance with very high-impedance planars or ultra-sensitive IEMs, so the score reflects strong likely compatibility without explicit measured confirmation.
Build Quality
93/100
Reviewer notes an 'impressively heavy black case', professional-grade feel, separate analog/digital power domains, quality Talema supplies and decent caps, and a neatly laid-out internal design. The high-quality reed-relay volume and overall component choices support an excellent build-quality score.
Features Connectivity
89/100
The unit includes an AKM-based DAC implementation, an Amanero FPGA USB input, and a high-resolution 256-step reed-relay volume control; the product is described as a headphone amp / pre-amp / DAC. Combining an integrated DAC, USB input and true-balanced topology puts it well above baseline feature levels even though the review does not enumerate every I/O connector.
Value for Money
86/100
Price listed at ~3299 and the review focuses on design and sonic choices without explicit commentary on price/value. Per guidance, a neutral baseline score is used because reviewers did not provide value judgments.
