Measurements of Xuelin iHiFi 770C were carried out by Roman Kuznetsov on the hardware-software complex RAA.

The Xuelin iHiFi 770C 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.


iHiFi 770C was given for tests by NEW COLISEUM
