Rank the tweaks, geeks!


How would you rank the general importance of the following gear (not room or electrical) tweaks. You can use your own setup and experience as your basis. If you tried something and it didn't matter, put it in a separate paragraph at the bottom with "didn't matter" next to it. If it doesn't apply to your setup, just don't include it on your list.

speaker wires
speaker isolation
interconnects
cable risers
component isolation
tube dampers
power cords for amps
power cords for preamps
power cords for other compnents
better capacitors (where?)
better fuses (where?)

Did I leave out an important tweak? Please add in as you see fit.

Think it's all snake oil and voodoo? Go watch some TV or take a walk and let folks on the thread have their fun. Because this is a hobby.

If you think that "everything matters" but are willing to go beyond that and suggest what would be the best first step toward doing something, please list the best first things to do. A "to do agenda" rather than a "priority list."

I was wondering about rankings *besides* room and electrical, but thanks for your contribution. All makes sense.

@ebm Another peek inside an empty closet.

I’ll leave it at there is only two things on that list I have not bothered to dabble with (risers and caps) and one I dabbled with that turned out to not be worth it (fuses).  Also dabbling with fuses can cause damage if not done properly. 

I let my vendor choose the caps just like all the other stuff they choose to put in there.

if I had to pick the most important key ones it would be isolation of components in general though even there YMMV.

Also I would add if one is smart about it none of those things need cost a fortune.
@ebm If you can take a few minutes to write blather, you can take a bit more time to contribute something you know of substance. Then again there's the usual option: take zero time and just skip the thread. Oh, yes -- have a nice day. 
Perhaps the most notable was "component isolation". I was a skeptic of most tweaks, etc, like most people start off. It’s just hard to believe that some of this stuff works. Many years back I read  about pumice stone under a CD player @ TNT audio(?). I hate guessing about something. The tweak was $3 worth of Pumice stone from a dept. store. OK, That’s cheap enough. So lefts try it. I bought 2 pumice stones and cut each in half. My mind was telling me that I could put an end to this ridiculous idea by disproving it. So, under the cdp it goes and...........................................................WHAT? Huh? It didn’t take long and I was hearing a bigger soundstage, and more air. The music floats on air rather than being cast or shot out from the speakers. (Hey, I ain’t no reviewer. I don’t know the fancy words to describe it. Said another way, "It sounded noticeably different and better.. From there I found a recipe for DIY roller blocks. These are even better.
From there I moved up the $$$$ scale to an Oyaide R1 power outlet @ $175. I felt really foolish spending my $$$ on this with NO $$$ back return offered. When I heard the difference IT made, I felt like someone was playing tricks on me. How could this be? I hate things which don’t make sense to me
