Class D amplifiers have very little phase shift

That helps,  it's where I thought they were measuring and that's  why the first graph was misleading they put the probes on the PCB. Not sure what jesskerry is on about I don't  consider myself to be anything other than trying to understand.

I don’t think the graph itself is misleading. It’s that is’ so very very rare. I have seen output impedance plots, rarely, but never one with phase also.

It’s truly something for the geeks.

Yet you were one of the first to to pat the OP (who has no idea) on the back in the other now deleted thread, without knowing as you say yourself " consider myself to be anything other than trying to understand" try to understand what I just posted above.
Good one! it’s a no wonder I don’t post.

 Because some of these comparison modules are measured with/without their output filters insitu, and the manufacturer has used Audio Precision "very high order" external “test filtering” instead for the graphs, and/or the frequency knee of the output filter they use if used, is totally different to the one it's being compared to by the one doing the comparing, which will directly effect the amount of phase shift down lower in the audio band as those of us all know.

I only know of one person who could put together such a long sentence that in the end is so convoluted that it cannot be proven or disproven.  I would try to answer it, but it is the opposite of building an argument from parts that logically form a whole.

Hahahaha.

What thinking human could care when the insensitivety to phase argument stands? If you want to bow down to measurements please design us the perfect amp. That doesn't waste power 
like incandescent light bulbs.
And doesn't sound like dog waste.
