Amazing video! thanks to the OP...
All i had seen in this video confirm my experience ... Acoustics of room/speakers is the key...
So crafty these people were they miss this central point and were focussing on gear design and alimentation , mechanical vibration and turntable stability etc ... For sure all this matter...But they all miss the system/room/ears acoustics problem as the main one ...
What is admirable is their creativity , they are not just passive consumers though ...
But i am in ectasy with a 1000 bucks modified system embedded in a good room acoustic ..
I am proud of my creativity without the shame related to some missing simple factor : system/room acoustic with then the gear focussing to compensate the acoustic ignorance and the heavy money cost is a consequence ( the grin on their faces and on the face wife is revealing ) ...
Am i a creative fool also ?
Perhaps but my money investment is 1000 bucks...
My creativity is like theirs in less spectacular and less skillfull as some ,but i modified all my system too ...
I learned acoustics basics as the most important factor , now i only listen music at low cost ...😊
