On-line comparison and selection services for HiFiMan HM 802 Balanced Card Balanced Mode

The automatic selection of the optimal AMP models from HiFiMan HM 802 Balanced Card Balanced Mode.
from the measured power parameters of the amplifying part and the measured parameters of the headphones for different purpose of use.


Close

Measurements of HiFiMan HM 802 Balanced Card Balanced Mode were carried out by Roman Kuznetsov on the hardware-software complex RAA.

The HiFiMan HM 802 Balanced Card Balanced Mode test was conducted as a black box test, without regard to cost and prestige. This is the basic principle for making measurements, measurement reports and developing tests in RAA.

I believe that it is important to do not make an absolute assessment of the device, but an aggregate assessment when working together with a headphones and taking into account external factors. This allows you to effectively reveal the potential of the entire set of devices or to make a more optimal choice of components.
