Cryogenic experience wanted. Constructive please

I have been saving and working to upgrade my system and its been paying off. I'm finding listening to small changes assessing then going back or moving forward, largely paying attention to tone ( probably harmonics really) does it sound more like a violin etc. Also paying close attention to feeling of music ( does the change bring me more involvement with the content) have been reading about cryogenic treating speaker driver. Could anyone share some insight to who, where, what; or what not to treat. My drivers are Omega 8" alnico with hemp paper I believe. Is there a large risk in treating them. I mean physical damage not how they will sound. What would those of you who have done treatment to gear suggest doing cables and tubes even component all at the same time? Thanks for reading all that and any input is appreciated. Please no, does it work or how. If you have not had items treated and want to talk hype. Please refrain thx.
