On-line comparison and selection services for Acer Iconia Tab W500

The automatic selection of the optimal AMP models from Acer Iconia Tab W500 .
from the measured power parameters of the amplifying part and the measured parameters of the headphones for different purpose of use.

Measurements of Acer Iconia Tab W500 were carried out by Roman Kuznetsov on the hardware-software complex RAA.

The Acer Iconia Tab W500 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.
