DHA V226 is an affordable product in the Violectric line. It offers a competitive digital-to-analog converter, a balanced headphone amplifier, and a preamplification function. The digital-to-analog converter is based on the Cirrus Logic CS 43131 chip with a dynamic range of 130 dB and a non-linear distortion coefficient of -115 dB. DHA V226 has a USB-C connector and supports PCM 32-bit formats and a sampling frequency of 384 kHz, as well as DSD256.
The amplifier circuit inherits the technology of its well-known predecessors, V200, V280, and V281. Inside the DHA V226, you'll find the same natural, smooth, and enjoyable sound.

- High-quality operational amplifiers
- The power supply features a toroidal transformer and a total capacitance of 22,000 µF
- Output power: 23 V RMS (600 Ohms), 2800 mW (50 Ohms)
Multifunctional device
Headphone outputs or rear line outputs can be activated/deactivated using a switch on the front panel. The line outputs can operate with or without a volume control. Connect not only headphones to DPA V226, but also a power amplifier or active speakers and experience a compact and fantastically sounding headphone amplifier with a premium digital-to-analog converter and preamplifier.
Thanks to the innovative technologies implemented in the Violectric amplifier, it has emerged as the winner of numerous tests among headphone amplifiers. The amplifier in DPA V226 was designed to provide maximum sound quality for headphones with any impedance. By employing technology specifically optimized for dynamic headphones, it has been possible to significantly reduce circuit noise and achieve low distortion levels, meeting the high demands of Hi-End audio.
The internal circuitry operates with low sensitivity, ensuring minimal internal circuit noise that is practically imperceptible when listening. The internal circuit voltage level has been increased to 50 volts, making the amplifier an ideal partner for headphones with high impedance levels. Over 90 percent of amplifiers on the market operate with an internal voltage that is more than half of DPA V226's. This model features discrete, separate amplification circuits with eight transistors per channel.
The Violectric DPA V226 possesses minimalist versatility. The analog inputs consist of two unbalanced stereo RCA inputs, while there is only one digital input - USB-C. There is only one analog output - a balanced RCA connector. On the front panel, there are balanced XLR connectors, a 4.4mm Pentaconn connector, and a 6.3mm connector for headphones.
Special preamp function
As a special function for the unbalanced output (RCA), it can be set to "pre fader" or "post fader". "Post fader" means that the volume control affects the level of the output signal. "Pre fader" means that the buffered input signal is sent unchanged to the unbalanced output (RCA). This setting can be useful when the unbalanced output (RCA) is connected to a device with its own volume control, such as a headphone amplifier.
After selecting the input through a special controller, the signal is sent to a buffer amplifier to achieve a low impedance state. Then, the signal is directed to the volume control, followed again by a buffer amplifier. Finally, the signal reaches the output operational amplifiers, which can be adjusted to different output levels through internal mini switches.
Depending on the type of headphones, the level adjustment can be done using the pre-amplification switches on the rear panel of the amplifier.
German quality
The exemplary level of construction quality guarantees excellent listening quality. Thanks to the numerous connection and routing options, the HPA V550 is the perfect central control element in a complex home audio system.
To meet the high Hi-End standards, Violectric consistently pays great attention to the selection and processing of components. The signal passes through the Alps RK27 volume control and then onto the transistor amplification unit.
Additional circuits protect the devices from direct current, overload, or overvoltage, and delay the power-on process to protect the headphones. All components are meticulously assembled by hand and installed in a slim case made of black anodized aluminum with a one-millimeter thick front panel.
