What makes the biggest difference in sound quality?

@mahgister why you even bother answering to this gentleman?
Not worth your time. You are in a much higher league of understanding that he will never achieve.

Some people just don’t know beyond what they believe, which is where I excuse myself; beliefs is not how science works.

What one believes has no place in a technical discussion if the “facts” you believe have no correlation with actual science.

Because i was thinking erroneously that he will be able to discuss audio matter, not only selling his devices... I like to learn...

Some other sellers are more honest and give very good information here, like atmasphere for example...

I am naive more than most ....I know... 😁😊

One of his thread has been erased where he articicially opposed for the need of his business objective measurements in engineering and subjective perception, forgetting completely the acoustic field where there is ONLY a continuous correlation PROCESS between this two aspects and not opposition and the obligation to chose one over the other...

He perceive my arguments as threats to his business then refer people with some inuendo to my virtual page photos... Pathetical move...

@mahgister - I thought you might be interested in the statement made by former dealer @richopp in a different thread where he said:

Accuracy in reproduction depends more on YOUR ROOM than any specific gear.  Once you realize that, the rest is just a hobby.
