Measurements of xDuoo XP-2 UAPP were carried out by Roman Kuznetsov on the hardware-software complex RAA.

The xDuoo XP-2 UAPP 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.


xDuoo XP-2 was given for tests by Xtenik Audio

Комментарий к оглавлению отчетов xDuoo XP-2
Довольно любопытный результат для воспроизведения 192 кГц - он не отличается от 96 кГц при тестировании в любых условиях. Это и плееры от смартфона и Windows 10 c WASAPI.
