Using a computer sound card and FFT software is not a great way to go for measuring audio equipment. The bandwidth is limited to 20kHz, including harmonics. This means that harmonic distortion measurements of higher frequencies will be limited and perhaps misleading. Also, the input voltage capability is limited to only a few volts and is not tolerant to overloads. To use it with a power amp will require building some type of input attenuator.
