DHA V590 MKII
DHA V590 MKII
DAC/headphone amplifier combo with superb conversion quality and robust amplification.
Violectric DHA V590
Reference-grade DAC, 32-bit Resampler and Powerful Headphone Amplifier
The Violectric DHA V590 combines a high-end D/A converter, 32-bit resampling/reclocking, preamplifier and powerful headphone amplifier in one unit. Digital signals arrive via XLR, coaxial, optical or USB, are processed by the 32-bit resampler/reclocker with femto clock, and converted by the ESS-Tech ES9026 PRO DAC (up to 384 kHz and DSD over PCM) into superb analogue audio.
Highlights
- 32-bit resampler/reclocker with 180 dB dynamic range for virtually jitter-free playback
- ESS-Tech ES9026 PRO DAC, 2× 32-bit converters per channel, –112 dB THD+N and 123 dB dynamic range
- ±18 dB pre-gain for perfect matching of sources and headphones
- Motorized Alps RK27 volume control and separate balance pot
- Four powerful amp stages delivering 6400 mW @50 Ω and 21 V RMS @600 Ω
- DC and overload monitoring with delayed headphone activation
Connections
- Analogue inputs: 2× RCA unbalanced, 1× XLR balanced
- Digital inputs: XLR, coaxial, optical (24 bit/192 kHz), USB up to 32 bit/384 kHz PCM and DSD64–512
- Headphone outputs: 1× 4-pin XLR balanced, 2× 6.3 mm jack unbalanced
- Line-out: 1× RCA unbalanced, 1× XLR balanced (gain adjustable ±18 dB)
Built with premium components – including two toroidal transformers with over 35,000 µF filter capacity – and housed in a solid black anodized front panel, the DHA V590 is the perfect control centre for any high-end audio system.
Remote control included for input selection, resampling mode, volume, output and mute.
