Test report FiiO X7 II: Fast Roll-Off Linear phase (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 product 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.
