Isoaltion why so many options? Confusing

With so many tweak options what works best, I have heard so many variables to brass isolation of components, maple, etc etc etc. Doing some research I have found some cheap solutions to isolating my components (Maple) for my speakers. Brass spikes for my speakers now I am looking into glass

Here are a couple of cost effective approach that I have found during my research:

Ebay maple item #120092997874
Ebay brass isolation cones #280090083911

I have even found glass isolation spikes, nice and fat and aluminum but I dont know much about glass and aluminum qualities to isolate components, any experience or knowledge of these products???? I would really like to know! With so many options what really works best? Is it an opinion base subject or a scientific approach to isolation of your components? Does spending more money really means your getting the best or "we" are just making unwise decisions? I consdier myself a blue collar worker, working for the City of Chicago as a Firefighter doesnt mean that I am rich but I do have to take a conservative approach to making my music sound best with the lowest cost as possible, not being CHEAP just conservative on how I spend my hard earned money.

Just looking for honest advise on tweaks, especially isolation of components. Thanks to all in advance
