On-line comparison and selection services for EVGA Nu Audio

The automatic selection of the optimal AMP models from EVGA Nu Audio .
from the measured power parameters of the amplifying part and the measured parameters of the headphones for different purpose of use.

Measurements of EVGA Nu Audio were carried out by Roman Kuznetsov on the hardware-software complex RAA.

The EVGA Nu Audio 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.



EVGA Nu Audio was given for tests by EVGA

Комментарий к профессиональному отчету EVGA Nu Audio HP Out Master 33
Это отчет для выхода на наушники, где громкость была снижена через Master регулятор. Значение 33%.

Этот отчет противопоставляется отчету HP Out Vol 67. Там такая же амплитуда на выходе, но через аналоговый регулятор Maxim DS1882.

Это отчет для выхода на наушники, где громкость была снижена через дополнительный аналоговый регулятор Maxim DS1882. Значение 67%.

Этот отчет противопоставляется отчету HP Out Master 33. Там такая же амплитуда на выходе.
