No tweaks will replace a method to adress embbedings control in the three working dimensions for any audio system : mechanical (vibrations/resonance control) electrical (noise floor level of the house and EMI and RFI ) and especially acoustical ( passive acoustic treatment+mechanical Helmholtz control)...
That being said some "tweaks" like Schumann generators (S.G.) and ionizers add something no other device will add to the acoustic impression, but the level of audible improvement will be function of your acoustic room quality to begin with ... Some will hear no improvement and no change, not because there exist none but because their system is too noisy and their room untreated and uncontrolled... the same people will laugh at "tweakers"....
No one must begin embeddings controls with "tweaks" even surprizing one like S.G. or ionizers...
ACOUSTIC is most important key.... Nothing else....
Listening a speakers/room relation has nothing to do with cycling analogy...
I honestly can’t figure out why people fall for this stuff. my other hobby is cycling. We don’t have these kinds of products in cycling. The product either works or it doesn’t. There’s no in between.
