Measurement's report ASUS Xonar Essence ST - Reference Audio Analyzer

ASUS Xonar Essence ST

About this report
This is a report for professionals with a suite of test of headphone amplifier.
You can see a simple report for "dummies" with explanations of the main characteristics for ASUS Xonar Essence ST

A suite of tests for a headphone amplifier can be applied to just a universal output without a formal presence of an amplifier, if in this mode you can connect headphones to this output. Based on the results of the tests, you can understand the real picture, is the output powerful enough or not, with the initial data on the circuitry as a "black box".

Line-out, differences from the output for headphones and speakers

Advantages and disadvantages of balanced amplifiers

More detailed

Measurements of ASUS Xonar Essence ST were carried out by Roman Kuznetsov on the hardware-software complex RAA.

The ASUS Xonar Essence ST 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 оглавлению отчетов ASUS Xonar Essence ST
STX - Полное выходное сопротивление среднее в диапазоне 40 Гц - 15 кГц: 11.7 Ом
ST - Полное выходное сопротивление среднее в диапазоне 40 Гц - 15 кГц: 7.4 Ом

Это ошибка или действительно ST так значительно отличается по сопротивлению? Кроме слота и косметических изменений не должны отличаться.

Сопротивление высчитывается по разнице абсолютных уровней АЧХ, измеренных под разными нагрузками. Если под низкоомной нагрузкой уже начинается рост искажений от ограничения тока, то уровень получается чуть ниже, а итоговое значение сопротивления больше. В старых измерениях такое иногда встречается, в новых обычно измерение производится до начала каких-либо искажений.

Я посмотрел на исходники, там в случае с STX небольшие искажения были и соответственно значение немного преувеличено.
