This is a report for professionals with a suite of tests for line output devices. Alternative version of the report for "dummies" in development.
A suite of tests for the line-out can be used for headphone or speaker output if in this mode it is possible to use the device as a source for connecting an external amplifier or if such a test suite can give more information about the implementation of the DAC in the device.

More detailed
Measurements of Sansa Clip+ were carried out by Roman Kuznetsov on the hardware-software complex RAA.
The Sansa Clip+ 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.

Неплохо звучала эта кроха на хорошие наушники Сеннхайзер, но меня всегда удивлял ее отвратительный звук при подключении к хорошим студийным мониторам. Теперь все стало ясно - без нагрузки у нее чудовищные искажения на выходе для наушников. Впервые встречаю усилитель, у которого с ростом импеданса нагрузки искажения не падают, а возрастают.

Вы бы смотрели не только на саму картинку, но и на "параметры отображения графика" под картинкой.
