I know for a fact that acoustics knowledge matter more than gear price tags...
When you have a good balanced system you forgot the sound. Suddenly any musical album reveal his unique acoustic trade-off interesting choices and the music is well served so much you cannot stop listening the music not the sound.
How is it possible with a relatively low cost system as mine ? With acoustics basic applied among other factors...
I was accused to bash high end gear because of my claim😊 ... Complete misunderstanding who reveal the ignorance abyss put by marketing publicity in audio forums and magazine and in people head... I discovered it late in my life and recently and progressively all along my acoustics journey ... ( acoustics concepts are not room acoustic panels by the way )
No acoustics concepts and experiment will put a 100 bucks speaker on the same podium as 10,000 bucks one... Common sense and common place fact ... But acoustics will make possible an improvement in the limits of these different designs in an astounding way ... I am flabbergasted by acoustics not by the gear...
