Instead of speaking of "tweaks" like some improvised, trying, costly, improving miracles incomprehensible solutions; I speak about 3 embeddings( or 4 the acoustical problem being double side) for an audio system, and of the way to systematically, experiments with ears, a continuous improving increased with only low cost materials and homemade solutions...
Never mind any tweaks.... No tweak by itself will resolve the embeddings problem...
How do we insert an audio system in an electrical grid ? How do we transform the acoustics of the room where it will be playing ?How do we controls the internal resonance of each piece of gear and mechanical vibrations of the street, the house, the desk etc. where this system is?
ALL this 3 problems are so connected to one another that NO isolate tweak will do the job alone and be optimal by itself alone...
The implementation must be step by step, and the ears must use each tweak against other tweak, in an improving and compensatory process where each solution complement another, for an optimal solution in the 3 dimensions (mechanical, electrical, acoustical)...
And you know this cost almost NOTHING.... I bought anything except cheap materials...
This is the basic audiophile problem....The embeddings dimension...
Forget costly tweaks …. Remember that most of the times your system is already very good but badly embedded...
This is my experience...
The S. Q. /price ratio is not linear.... The embeddings solutions made the difference and narrow the gap between low cost system and costly one most of the times....Engineering design, if we stay and compare products on the same rung of the scale, cannot give an improvement comparable in each of the 3 rungs scale, low Hi-Fi, mid, and high costs, to a rightfully embed audio system compared to one that is not in the same rung.... Engineering so good be it cannot make miracles and replace the 3 optimal embeddings audible qualitative powerful effect.... In the future with A.I. probably.... But we are not there....
