I am happy not because i enjoy music and declare to myself that the sound is so good...It is yes, but...
We all think , most of us that our sound is good...
Especially people with costly piece of gear....
I am happy because i know, i dont believe, i know, HOW i has prepared acoustically and psyco-acoustically my speakers/room to reach my actual sound quality...
I dont boast about my gear and his " marvellous" sound like some , i only know what my sound experience was BEFORE acoustic treatment and acoustic mechanical control, and AFTER it...
I have no way to compare my sound experience to your sound experience...
But i know what most people will never know: the DIFFERENCE between acoustic tuning optimization before and after...
Then i am happy with my soundefield, but what make me more happy is that i know HOW we can replace upgrade obsession by acoustic and WHY i will never upgrade and throwing any more money...
Basic experiments in acoustic science will make you free of pseudo science: measurements of gear pieces to justify upgrade...
Measurements are useful for designers not so much for customers....Most customers have no idea how to control the acoustic cues and experience in their room anyway...
Then be happy with what you have yes, if not, try acoustic... Dont upgrade save if some basic piece of gear is not on the same quality level than the others...
This is my advice....
