    On-line comparison and selection services for (769) FiiO X3 III Unbalanced Low

    The automatic selection of the optimal AMP models (790) from (380) FiiO X3 III Unbalanced Low.
    from the measured power parameters of the amplifying part and the measured parameters of the headphones for different purpose of use (795) .



    Измерения FiiO X3 III Unbalanced Low проведены Романом Кузнецовым на программно-аппаратном комплексе RAA.

    Тест FiiO X3 III Unbalanced Low 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.
