My understanding of the OP's comments is that no matter what you have, you should optimize it. You optimize it individually and you optimize it in relation to everything else in the environment. I believe you should always start with the room because you don't want a speaker that is too big or too small for the room. Once you decide on the speaker, you then need to place it appropriately relative to listening position and you should consider isolating it mechanically. There should be some acoustic treatment and the signal you feed to it should be as pure as possible. You should go through every component in your room and see whether or not you've optimally matched it to other components and that you have optimized it mechanically, electrically, and acoustically.
A principle guiding the wise audiophile life
There is one law, or best said a principle, guiding the wise audiophile life :
What matter is not the gear pieces price or his design, it is up to our budget limit to pick the right stuff for ourselves and our needs.
What matter is the way we installed together the mechanical,electrical and acoustical working dimensions of any chosen system/room...
As a consequence of this principle this is his corollary:
The mechanical electrical and acoustical controls,devices,tweaks, parameters, cannot be replaced by one another if we want to reach an optimal result in sound quality.
Vibrations/resonance controls cannot replace or be replaced by acoustics parameters controls or EMI shielding and grounding for example.
The greatest error we can do is buying and just "plug and play". Then upgrading a piece part by frustration or dissatisfaction, without learning how the whole system may,must,can behave in a specific room for our specific ears (psycho-acoustics).
The other error will be to cure one problem with a gear upgrade before trying to understand what is the problem.
This must be meditated by any beginners before "upgrading" and after "upgrading"...
There is no relation between a piece of gear or a system/room before and after his optimal mechanical,electrical and acoustical installation. None.
It is the reason why reviews do not tell all the truth there is to be tell ...
This resume what i have learned.
