It’s hardly a discussion when you post bold claims, which you know to be contentious and that fly in the face of well understood engineering principles, then strop out of the thread and name call when asked to clarify those claims and your understanding of a process.
I don’t know Marian nor his background, but from his post and others I assume he has post grad-level degree in a science or engineering subject, but revealingly I don’t know for sure, because — as far as I am aware — he’s never posted that information in order to try claim that his knowledge is better than anyone else’s. Rather his posts speak for themselves and come across as level headed and well-informed.
You say you’re a ‘audio hobbyist’ — which suggest you are still learning — in which case why would you not want to learn and improve your understanding of a subject and potentially correct a mis-understanding. Or at least find out where your understanding is diverging.
What do you gain by digging in?
Has there never been times when you have been wrong about something? I sure as well know I have. I’ve also learnt that if my views or understanding flies in the face of conventional wisdom, then it’s good to have that view challenged and be open to understanding where I may be wrong before digging my heals in.
Or at the very least you need to come up with some pretty damm hard evidence and research as to why your thinking might be correct and conventional wisdom wrong. But just posting on forums in the hope of finding an echo chamber to support your views without any evidence, seems self-defeating.
What harm is there in engaging with Marion’s post and acknowledging the areas that you might be unclear of? If you’re genuinely open to seeing where understanding diverges I expect you could even do that via DM f oyur rather not do that in public.
Maybe try and engage, ask questions, try not to ‘win an argument’ rather seek to understand why your views might diverge from conventional wisdom and be open to changing them if need be.
At the end of the day I expect we’re probably all on the same page in terms of wanting good quality audio reproduction, hardly a partisan subject.
