What makes the biggest difference in sound quality?

Ted, if your products are as good as your ability to decently discuss facts, probably nothing you sell 😂

You asked why I don’t have pictures of my systems… simply, I don’t like creeps that can’t discuss technical facts without making it personal like you did because you can’t defend the nonsense you claim, into my homes.

Those who matter, and love have access to any of my systems, or everything I have both in the USA and Spain any time they want.

I do not need to prove anything, much less to you, because I am not selling anything or trying to convince people to buy into bs to make a living.

I am accustomed to interact with reasonable people, that just like me, can discuss technology and math based on facts and if someone makes a better technical or mathematical argument we learn, without making it personal. Reasonable people usually are humble, like to learn, have the ability to differentiate between bs and facts, but the best quality reasonable people have is their intrinsic ability to separate a discussion and their fellows.

Apologies for my grammar a word choices, English is not my native language.

He did just that with me instead of arguments in a meaningless opposition he created to impose his products...(objective versus subjective) My argument was centered around the evident fact that all audio science in electronic or acoustic is the search for a correlated sets of experiments ... THEN Our subjective taste must be educated by acoustic experiments for example... Is it not clear? Instead to mock me he say to people look at his system (mine) in my virtual page......

No honest person do that... I dont give a dam about mockery but i dislike people who hypocritally attack someone instead of answering SOUND arguments....

He proved himself to be guided by his seller agenda more than by truth...

I don't show my system because if I take a picture of the equipment it will steal the musical soul and render it mute.

The Room.  Treat it and get that right, then drill down to the others. 

When weighing the advice of others, it pays to understand their perspective. This is the best way to place audio advice in context.
