1- What people call "tweaks" are only one by one, each of them, some elements of some set of parameters in one of the 4 dimensions of the embeddings of any audio system... ( mechanical resonance, electrical grid, passive and active acoustical fields)
2- Sometimes not knowing these 4 dimensions of the embeddings, people call "tweaks" some crazy or less crazy inventions, simple or less simple device, most of the time not so cheap device, even costly...
3- Not knowing these 4 dimensions people dont work systematically in function of them and dont experiment the powerful transformation of their audio system linked to each of them...
4-Unconscious of the power of this 4 embeddings, people act and work on their system erratically and very approximatively and without being conscious of the powerful potential linked to these "tweaks" or various parameters of the embeddings ...People dont realize that these dimensions are complementary and works together toward the peak potential S. Q. of any system...
5- These dimensions I worked on them always with some homemade and very cheap materials... No "tweaks" I use were bought, except I use some cheap materials and electronic components I modified myself(10 bucks each for example for Chinese Schuman Generator) to linked all 4 embeddings...
Dont buy tweaks, replicate them , retro engineer them, invent your own....It is more simple than you imagine... I am in no way a very gifted manual worker....
6- The results is not a more or less slightly modified audible sound mostly but a complete transformation.... Calling that "tweaks" dont do any justice to the works and dont describe at all the way and method each one of us must takes to embed any audio system....
7- Experimenting and playing with these 4 dimensions is more fun than buying finished products and way more self gratifying....
8- No audio system sound at his top level out of the box and located in a non treated room... NONE...
9- Most people has never listen to their own system at all.... They dont know what their own system can deliver in quality....
10- 90% of any electronic component upgrading is not necessary, and if necessary is not made in a rational way or in a judicious way....It takes me 7 years to learn that and I pay the price.... My best to all....
