On-line comparison and selection services for Breeze Audio USB DAC-PD01

The automatic selection of the optimal AMP models from Breeze Audio USB DAC-PD01 .
from the measured power parameters of the amplifying part and the measured parameters of the headphones for different purpose of use.


Close

Measurements of Breeze Audio USB DAC-PD01 were carried out by Roman Kuznetsov on the hardware-software complex RAA.

The Breeze Audio USB DAC-PD01 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 Breeze Audio USB DAC-PD01
Линейный выход этой копеечной платы, поражает красотой своих графиков, которой могут позавидовать многие "Хай Энд" устройства! Доминирующая вторая гармоника и отсутствие гармоник высших порядков, особенно нечетных, говорят о благозвучии устройства и точности воспроизведения музыкального материала.

Нормальные результаты. Мог бы быть конечно лучше график джиттера. Выход для наушников сделан номинально, там очень высокое выходное сопротиивление, мало какие наушники с ним будут играть с достаточно громкостью. Устройство стоит рассматривать лишь как ЦАП.
