- LOWEST NOISE due to very small internal gain. This makes the amplifier's inherent noise inaudible.
- HIGH OUTPUT VOLTAGE due to 50 volt internal operating voltage. Therefore ideally suited for high-impedance headphones.
- HIGH OUTPUT POWER due to powerful amplifiers that can deliver far more power than even the most demanding headphones can use. Therefore ideally suited for headphones with low impedances and also planar magnetics!
- HIGH DAMPING FACTOR due to lowest output impedance. Therefore ideally suited to drive even the most difficult headphones without interference, guaranteeing an uncompromising frequency response.

Functions
The rear line inputs can be selected via a switch on the front. After the RK 27 volume control, the activated and buffered signal goes to the power amplifiers, which are a further development of the famous V200 circuits. Connect your headphones to the HPA V202 and enjoy a compact and fantastic-sounding headphone amplifier with the acclaimed natural, smooth yet precise Violectric sound.
