No one can tell you whether/how your system, room and/or ears will respond to some new addition. There are simply too many variables.
LIKEWISE: no one can possibly know whether a new addition (ie: some kind of disc, crystal, fuse, interconnect, speaker cable, etc) will make a difference, in their system and room, with their media and to their ears, without trying them for themselves.
Many companies offer a 30 Day Satisfaction Guarantee, so- those that are actually interested, have absolutely nothing to lose by trying (experimenting with) such.
Anyone that knows anything about the sciences, realizes that something like 96% of what makes up this universe, remains a mystery.
For centuries; humanity’s seen, heard, felt and otherwise witnessed phenomena that none of the best minds could fathom, UNTIL they developed a science or measurement that could explain it.
The Naysayers want you to trust their antiquated science (1800’s electrical theory) and faith-based, religious doctrine, BLINDLY (their credo: "Trust ME!").
Theories have never proven or disproven anything. It’s INVARIABLY testing and experimentation that proves or disproves theories/hypotheses.
IF you’re interested in the possibility of improving your system’s presentation, have a shred of confidence in your capacity for perceiving reality and trust your own senses: actually TRY whatever whets your aural appetite, or- piques the curiosity, FOR YOURSELF
