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 SMSL AD18 were carried out by Roman Kuznetsov on the hardware-software complex RAA.
The SMSL AD18 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.
