On-line comparison and selection services for FiiO X7 AM1

The automatic selection of the optimal AMP models from FiiO X7 AM1.
from the measured power parameters of the amplifying part and the measured parameters of the headphones for different purpose of use.


Close

Measurements of FiiO X7 AM1 were carried out by Roman Kuznetsov on the hardware-software complex RAA.

The FiiO X7 AM1 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.
