Test report xDuoo x10: Slow (report for a pro)

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.

One device can have multiple reports in different modes and with different a suite of tests.

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.
