What makes the biggest difference in sound quality?

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 why you even bother answering to this gentleman?

@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.

Thanks it is my experience also with 2 years full time acoustic experiments in my room...

Thanks for the quote.  Funny those who say your room it is last.  Some here may have been to audio shows (CES, maybe) and the comments after the show are ALWAYS the same:

"High End Manufacturer X (pick your fav here) was in a hotel room and his/her stuff sounded AWFUL!  In my room, it is awesome!  I don't understand why these companies do this to themselves" (or something close).

Years ago, many "High End" companies stopped going to CES (when it was CES and not a computer show if anyone one here remembers those days in Chicago) because hotel rooms were SO BAD and the comments from potential customers were horrible.

You can review such stuff in The Absolute Sound or Stereophile older issues if you wish.  J. Gordon Holt did a bunch of articles on this, as I remember, as did Harry Pearson, I believe.  But hey, what do THEY know, right?

Anyway, as I posted earlier, the old cliche is, "you pays your money and you makes your choice."  You do whatever you want and these days, you are free to make up your own facts about everything, evidently.  As a dealer, I put our best stuff in rooms that we could not get to sound very good, and some average stuff in those same rooms sounded "better" to the buyer.  I sold him or her what they LIKED.  Did not matter if it was not very good.  It was a business, not a church with me preaching the "truth" to customers.

You do whatever you want; they are your ears.

Cheers!
