Измерения Violectric HPA V281 Balance проведены Романом Кузнецовым на программно-аппаратном комплексе RAA.

Тест Violectric HPA V281 Balance проведен как черного ящика, без учета стоимости и престижа. Это главный принцип измерений и разработки тестов в RAA.

Считаю, что важно делать не абсолютную оценку устройства, а совокупную оценку при совместной работе с наушниками и учетом внешних факторов. Это позволяет эффективно раскрывать потенциал всей связки устройств или делать более оптимальный подбор компонентов.
