Isn't the sentence "High Frequency Response Compromised" a bit general?

Or better, am I right if I take this as your assumption and not as the thesis?

Thanks for explaining, perhaps my English doesn't help me enough...

Stephano,
On the contrary, I think that perhaps sometimes we forget about some of the previous research and need to return back to the beginning and refresh our thinking. But at the same time that does not mean that any newer testing functions can not still be developed or that we have found everything we are looking for. Otherwise why do scientist still question Einstein's conclusions? To prove them right or wrong, they are constantly doing one or the other. Science does not and should not stand still.

Correct, its an assumption

Agreed,
but to sum up my feeling I'd say "give me something to try to understand, and - if the thing interest me and hoping to be able to follow it - I'll try to figure it!"

(and I don't mean to sound arrogant)

Stephano,
I didn't take your response as arrogant, not at all. I have nothing to direct you at at this particular time. What I am alluding to is that there seems to be some aspects of the audio electronics chain that still seems to be outside of our purview. How else to explain the different responses to changes in opamps or other devices that we measure as having basically identical electrical characteristics. I am not going to say that people do not hear changes, there is to much anecdotal evidence that this is happening. So how we measure that and quantify it is something that seems to be open for some new test, or perhaps just a refinement of what we are already doing. What I was originally trying to get at is that with ever faster computer processing perhaps we could refine the level of the testing we are doing, ever faster oscilloscopes that are not necessarily wider bandwidth, but finer resolution. I am not an electrical engineer, so I only speak in concept here, not absolutes.

Stephen,
I understand and agree with your attitude, and you must bear with me, I mixed two subjects in a single post.

It's way harder for me (and something suggests me that perhaps I'm not alone) to understand Harrison's approach, because - for example - his latest proposition isn't reported as consequent from something, nor - bynow - explained. It's just stated as the truth and is also contrary to common circuit theory (as DF96 wrote) as seems to me is used by serious industry manufacturer (e.g. vishay, for example), in University, everywhere and I couldn't read anything from Harrison about it. And I'd be interested in!

So, Stephen, I feel we are "in tune" (hope this is fine English)

Ciao,
Stefano

I do sometimes post material that is not yet in text books . Compiling these ideas into a book or a research paper takes time while the technology needs to be deployed and used in the field sooner. I did say that the amps under scrutiny in the solid state thread could win a patent or two and are light years ahead. The book is soon coming first get me the data
