About this report
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.

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

More detailed

Measurements of RME ADI-2-4 Pro SE ADC were carried out by Roman Kuznetsov on the hardware-software complex RAA.

The RME ADI-2-4 Pro SE ADC 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.

Комментарий к профессиональному отчету RME ADI-2-4 Pro SE ADC
Этот отчет располагается в категории ЦАП, но на деле это тест АЦП.

Наконец дошли руки до обработки отчета АЦП от RME ADI-2-4 Pro SE.
Если не изменяет память, то мы тогда в качестве источника использовали E-MU1616m, у которой нет сюрпризов в виде ESS hump и прочих странностей, но условно не самые низкие уровни гармоник низких порядков.

Это как выглядит оцифровка одной 1616m на другую 1616m
https://reference-audio-analyzer.pro/report/dac/e-mu-1616m.php

А это с 1616m на RME ADI-2-4 Pro SE
https://reference-audio-analyzer.pro/report/dac/rme-adi-24-adc.php

Итого, RME ADI-2-4 Pro SE получше с точки зрения сигнал/шум и может быть будет лучше для получения такого параметра как SINAD на уровнях около 0 dBFS, но линейность в виде лишних искажений хромает. Предварительно искажения ниже, чем у E1DA Cosmos, но принципиально с точки зрения линейности - хуже, чем 1616m. Так что 1616m пока полноценно не на что менять...

Интересно было бы протестировать Lynx Hilo ...
