headphone amplifiers HPA V202 and HPA V222

Violectric introduces two affordable high-end headphone amplifiers for headphone enthusiasts. Both models feature chief developer Fried Reim's much-lauded circuitry. The HPA V202 drives any asymmetrically connected headphone, regardless of its technology. The HPA V222 also features a fully balanced amplifier stage, powering any known headphone with the best signals. High output voltage, high power reserves and a high damping factor guarantee optimal amplification even with exotic parameters of the connected headphones. An additional gain circuit allows optimal level adjustment for headphones with very low or very high efficiency. The two headphone amplifiers are, like all Violectric components, "Made in Germany".
