Hell, despite my years at this, I need access to info and support. Nobody knows everything.Your post are wiser because for sure you are right...
But, it’s fun learning, isn’t it?
Too many tastes,ears and variables...
But when this is said...
My point about what are the 3 problems someone must adress to increase the S.Q. of any audio system before UPGRADING anything is always valid...
Without adressing mechanical vibrations controls, electrical noise floor controls and especially passive acoustic treatment and active acoustic control nobody knows what the gear he already own is able to achieve on S.Q. level...
And these embeddings controls on all three dimensions will need to be implemented one way or another...
This is my only discovery in audio....
And these necessary controls are valid nevermind the pieces of gear or the musical taste...
All system and ears are different but the ways to controls vibrations and acoustical settings are INDEPENDANT of our chosen gear and particular taste...
It is possible for example to tune a speakers/room system to any liking....introducing more dynamic or less etc...
But anyway i speak here because the pandemic and my retirement let me alone.... I dont want to convince anyone and only hope to be helpful to at least one...
Your post is wise and tactful and very interesting...
I thank you very much and give to you my utmost respect...
