Now why exactly do I want to show distortion graphs?
To prove your hearsay.
Because your the one that said
"Muti-inputs corrupt the signal to a degree and this is more noticeable with Class D"
Granted multiple inputs and the switches to do it do, create more distortion than just a single input with no switches.
But it stays the same feeding either solid state Class-D or a solid state Linear amp, to say you can hear it worse into a Class-D than a Linear amps is just plain BS.
