Am I right for this forum?

You cannot know how good will sound your gear (nevermind his price ) BEFORE it was rightfully embedded in the three working dimensions : electrical,mechanical and acoustical...

Then repeating a useless common place fact which is trivial truth as the better we pay the better the design you miss the message and the lesson of acoustics learning and other basic knowledge because you put your attention on price tags ..

We buy what our budget can afford... But we cannot know the acoustics potential of a system/room BEFORE we learn how to adress it ...

Any piece of gear and more so a system in a room cannot give his potential optimal without adressing the basic...

The system before and after is not comparable at all... I dont care about his price...All designs act the same at their worst if nobody reduce the vibration/resonance problem , and sound the worst in bad electrical environment and RFI and worst cannot reveal their truest quality in a bad acoustic environment ...

price tags dont change basic knowledge ...

What is really sad but true is that most people dont know that and dont want to know because it ask for studying, experimenting and a lot of time to do it right...It is more easier to buy and plug and called it high end 😊 ... The price tags will be the proof our system is good enough... But it is not so simplistic... Sorry... Dont take it personal please we only discuss...This is my experience not just an argument ...

How a low cost system can sound so good and how some very costlier system sound so bad even if they could be way better than the low cost system? It is relative to the basic knowledge of the users ...

This has nothing to do with a claim as preposterous as my low cost system may rival high end... It cannot ... But it can sound very good... And the high end may  not  sound so good because it is not installed to work at his peak potential ... The reason is knowledge applied or not in the triple embeddings  , not price ...

Unfortunately, sound quality usually improves as the equipment improves, and as the equipment improves it unfortunately usually costs more. Sad but true.

@immatthewj someone commented “cue Stuart Smalley”.  The OP wrote that the comment stung a bit.  I responded that he should ignore them.

Another sad fact:  "Garbage in/garbage out."  Garbage in an accoustically treated environment is still garbage.

You are blessed with a family that loves music as much as you do. I would say that the money you have invested in your system seems to be all you need with the other aspects of your life as they are. It seems as if there are so many different opinions as to what makes a person an audiophile. So many are shaped and molded to meet the hopes and expectations of how each individual  wants to present themselves. I wouldn't give this another thought.

Ah.  Okay.  I take it that the original Stuart Smiley comment had to do with positive affirmations about a system that did not cost a ton of money?
