Class D amplifiers have very little phase shift


Too many diagrams to post here, so I just blogged it:

The 20 degrees at 2 kHz argument is bunk.

 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.
Well jesskerry the best advice I can give is do as you say and don't  post. 
I meant ,misleading the way someone was trying to use the graph by saying ice 1200 modules had a huge frequency phase drop at 2khz.

@djones51

You are right.

I just meant to say that the geek who put it together never intended it to say what is being claimed. I make a lot of plots, so I feel sympathy for having your data ripped off to mean something you never intended. :)
