Violectric DHA V590²
Reference DAC, 32-bit resampler and high-power headphone amplifier
The Violectric DHA V590² combines a high-end D/A converter, 32-bit resampling/reclocking, a preamplifier and a powerful headphone amplifier in one unit. Digital signals enter via XLR, RCA, optical or USB, are processed by the 32-bit resampling/reclocking stage with a femto clock, and are then converted to analog by the ESS Technology ES9026 PRO (up to 384 kHz and DSD-over-PCM (DoP)).
Highlights
- 32-bit resampler/reclocker with up to 180 dB dynamic range for virtually jitter-free playback
- ESS Technology ES9026 PRO DAC with 4× 32-bit converters per channel, –110 dB THD+N and 124 dB dynamic range
- ±18 dB PRE-GAIN for optimal matching with any headphone/source combination
- Motorized Alps RK27 volume control and balance control
- Four amplifier stages with 6400 mW @ 50 Ω and 21 V RMS @ 600 Ω
- DC and overload monitoring, delayed output enabling
Connections
- Analogue inputs: 2× RCA (unbalanced), 1× XLR (balanced)
- Digital inputs: XLR, coax, optical (24 bit/192 kHz), USB (PCM up to 32 bit/384 kHz, DSD 64–256)
- Headphone outputs: 1× 4-pin XLR (balanced), 1× Pentaconn 4.4 mm (balanced), 1× 6.3 mm (1/4") jack (unbalanced)
- Line-out: 1× RCA (unbalanced), 1× XLR (balanced) (±18 dB adjustable)
With premium components — including two toroidal transformers and more than 35,000 µF of filter capacitance — plus a solid black anodized front panel, the DHA V590² becomes the audiophile hub of any high-end system.
Remote control included for input selection, resampling mode, volume, output selection and mute.

Who is the DHA V590² best suited for?
The DHA V590² is aimed at anyone who wants a single, self-contained hub for the entire headphone chain – from the digital signal all the way to the headphone output. With the strongest analogue amplifier stage in the lineup and a reference-grade DAC (ESS ES9026 PRO), it's the most consistent solution for listeners who want to do without a separate external DAC without sacrificing sound quality.
