On-line comparison and selection services for ASUS Essence 3 Balanced

The automatic selection of the optimal AMP models from ASUS Essence 3 Balanced.
from the measured power parameters of the amplifying part and the measured parameters of the headphones for different purpose of use.


Close

Measurements of ASUS Essence 3 Balanced were carried out by Roman Kuznetsov on the hardware-software complex RAA.

The ASUS Essence 3 Balanced 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.
