Measurements of Audinst HUD-DX1 Hi (Default Power) were carried out by Roman Kuznetsov on the hardware-software complex RAA.

The Audinst HUD-DX1 Hi (Default Power) 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.

Комментарий к профессиональному отчету Audinst HUD-DX1 USB Power
Регулятор громкости работает как на линейный выход, так и на усилитель для наушников.

При подключении по USB без внешнего БП на участке линейного выхода есть недоработка - при амплитудах выше -1 dBFS на линейном выходе наблюдается клиппирование сигнала. Регулятор громкости ситуацию не спасает. При при выставлении низкой громкости клиппирование с линейного выхода остается. Если выставить большой уровень - то клиппирование будет происходить раньше.

Аналоговая регулировка уровня громкости находится после участка с клипированием, а это значит, что это клиппирование неизбежно и на линейном выходе, и на выходах для наушников.

Для получения качественного звука необходимо уменьшить уровень на 1 дБ в программном плеере (или в микшере операционной системы) еще до ЦАП, и в этом случае проблема уйдет.

Проблемой вероятно является недостаточный уровень напряжения от USB. При подключении внешних блоков питания эта проблема уходит.
