Violectric HPA V202 headphone amplifier
Violectric's new entry-level headphone amplifier
The Violectric HPA V202 headphone amplifier is the latest result of the development of the acclaimed V200 circuit.
The technology of the HPA V202 builds on the roots of its award-winning predecessors (V200, V220, V280 and V281). The recipe for success is still Violectric's ability to create high-performance devices that produce a natural and pleasant sound. The HPA V202, like all Violectric devices, is handcrafted in Konstanz, southern Germany.
Features of HPA V202: Low noise due to very low internal gain. The amplifier's own noise is not audible to the ear and disturbs the listening experience.
High output voltage via 60V internal operating voltage. Therefore, it is perfect for high-impedance headphones that deserve a large output voltage swing.
High output power thanks to powerful amplifiers that offer much more power than even the most demanding headphones would need. HPA V202 is also suitable for low-impedance headphones and magnetostats.
High damping factor due to very low output impedance. That's why the HPA V202 is an ideal pair for hard-to-drive headphones with no negative side effects and guaranteed uncompromising frequency response.
