Where was the best reproduced sound you ever heard?

My last dedicated acoustic room homemade with 100 Helmholtz resonators tuned and others complementary devices.

I then learned why and how acoustics concepts and principles rules over upgrades of gear so impactful for sure a best design could be...

Most people cannot imagine this, it must be experienced... 😊

The important point is not my subjective opinion about my room , the important point is my objective conclusion : Acoustics knowledge matter more than most upgrades, save extreme one as going from cheap low cost speakers to Revel Salon...

Reading most audio threads we are conditioned toward the opposite : gear and price tags  matter the most...

Mbl 111e at United Home Audio in Annapolis Junction MD.   Still in a class all its own. Same setup at hifi shows: meh. 

mbl here too.

Vivid Giya G1 Spirt speakers, 4 Audionet monoblock power amplifiers (I believe they were “The Max”), Audionet Stern preamplifier, Grimm MU1 Streamer, Mola Mola Tambaqui DAC, Kronos turntable, arm, and cartridge, I believe Kubaka cables and cords, in a huge treated and impeccably set up demo room.  I do not know what power conditioner he used. Bill Parish is knowledgeable, professional and fair.  I am still trying to save my pennies for the Tambaqui I was auditioning.  Almost there.  

Well, if you've been an audiophile for 30 or 40 years and you've upgraded your components a few times, worked on the acoustics of your room, been incorporating best of the tweaks available, collected or have access to the best source material...

...then maybe (just maybe) it should be your own system. 😏
