DHA V590 MKII
DHA V590 MKII
DAC/headphone amplifier combo with superb conversion quality and robust amplification.
Violectric DHA V590
Reference DAC, 32-bit resampler and high-power headphone amplifier
The Violectric DHA V590 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 2× 32-bit converters per channel, –112 dB THD+N and 123 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 64–512)
- Headphone outputs: 1× 4-pin XLR (balanced), 2× 6.3 mm (1/4") jacks (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 V590 becomes the audiophile hub of any high-end system.
Remote control included for input selection, resampling mode, volume, output selection and mute.
