On-line comparison and selection services for Luxury & Precision L3 Balance DSD

The automatic selection of the optimal AMP models from Luxury & Precision L3 Balance DSD.
from the measured power parameters of the amplifying part and the measured parameters of the headphones for different purpose of use.



Измерения Luxury & Precision L3 Balance DSD проведены Романом Кузнецовым на программно-аппаратном комплексе RAA.

Тест Luxury & Precision L3 Balance DSD 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.
