Hey all, still getting used to this thing, I see that cd players are generally rated for 2 volts rms output so I was starting there. I see that as you increase the output of the internal generator the overall amplifier output distortion goes down.
I would look at the gain when you are testing. A lot of amps/intg amps/receivers will specify the input signal level to achieve the rated output power. Thd may go down as power goes up but the snr (or thd + noise) tends to go up as you are getting near the limits of the amp. Some amps with low gain are going to require a larger input signal. With a receiver or integrated amp (or power amp with gain controls), the Standard that I have found is to set the gain for 29dB and adjust the level of the input signal to achieve the desired output level.
Man I appreciate that, I have a lot to learn in this area as much of what you said went over my head as of now. I’m going to play around some more and return.
