I was trying to answer a question on that forum and the moderator @ctsooner blocked my posting privileges indefinitely.
This meant I could not ask him what the problem was.
I am very careful to not violate forum rules on any site and I know I didn’t on this one as well.
Since he is active on this form, now I can. The topic to which I was responding had to do with how THD affected ’timing errors’.
SO I guess the question is, at what point does the THD get so low that the timing errors it’s adding are no longer relevant.
To which I responded:
What is meant by ’timing errors’ in this post?

You have to scroll to see my response.
This is because THD has nothing to do with ’timing errors’; but I really didn’t know what the poster meant by that, so I asked for clarification.
Richard has posted on that forum that amps with zero feedback have less timing errors. But what is meant by that was not defined. Anyone familiar with filter theory knows that phase shift affects the amplifier at its extremes of bandwidth since essentially the stray capacitance and the like that rolls off the bandwidth is acting as a filter, usually one of 6dB/octave. If you look at the input vs the output of the amp on an oscilloscope, the output will appear to be delayed in the region of the phase shift. Is this what Richard was talking about?
I find it really odd that I got suspended on that account but maybe it was something else; however the email I got seemed to suggest that my question was the problem.
Maybe ctsooner could elaborate?
