And the biggest influence on sound quality is...

Funny that you post this. It has been my experience over many years that matches yours. The quality of the recording and engineering/production makes ALL the difference in the world. Garbage in, garbage out. It does not matter how resolving the audio setup can be, a bad recording will sound bad. Conversely, a very high quality recording that has been produced and engineered well... will make a good system sound sublime. I don't doubt that the quality of the component will make a difference. But in my experience the recording itself makes a bigger difference. My two cents...

I would think speakers would be before the room.  

I would put the room first, quality of the recording and then speakers third, though I am not 100% sure what you mean by the set-up.

@audiorusty Hello. By setup I meant the position of the speakers and the listening seat.

That is what I was thought you meant. Thanks for clarifying.
