Great product !
If you want to seriously get into measurement but you can not afford kilos of money, go buy it !

Be aware of the Zin, for small signal it starts around 600Ohm, but THD+N of 140dB is there !

With a really good osc (janascard dot cz, another great piece of hardware) I don't have any harmonic ! just noise floor around -140dBFS (with 16384 fft points).

only 2 minor concerns:
- I hate usb-C , it is not harsh enough...
- same for the jack if you want to convert amplifier outputs

So it's really a great product !
