Question How to test T-amp?

I use RMAA and Arta for soundcard, amplifier and speaker tests with Sony Receiver that has normal ground: however, T-amp outputs do not have common ground. How can I test it?

You can try a resistor divider, works for me.
I use various loads but 4R-1R-4R in series works pretty well for me. I take the signal off the ends of the 1R resistor. Sometimes I need a DC blocking cap, sometimes not. Best to use one if you are not sure.
Take the Speaker Voltage Test!
