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."

Which of the tweaks on your list were most important to deal with first?
I'm probably an atypical audiophile.  After 5 years of research I'm nearly finished completing my bucket list high-end analog/digital audio chain hoping to land somewhere mid-fi (couldn't think of another term).  Awaiting funds to purchase speakers and cables.  So I'm addressing all the non-tube tweaks simultaneously.  
A few members have recommended cleaning ears.
Well a proper ear cleaning can only be conducted in a hospital or similar.
Ear syringing is ineffective.
I had a proper ear cleaning done a couple of years ago, by a .specialised.
I watched the whole procedure via a video display .
The equipment used is a probe with various miniature  tools and a camera- It is inserted into the ear cavity and extracts -In my case at least 60 years of wax , dirt and hair build up! The specialist cut , jetted ,vacuumed and  snipped inside my ear canal , removing large chunks of hard wax -Ugh . I could smell the stuff as it was flushed out!
Finally he broke through endless muck -just like a tunneling machine , to reveal a pristine ear drum. 
The process cost 3000 Baht for both ears - about $US 100.
At the time , I considered the best money spent on anything ever  .It was that good.
As a comparison in audio perception improvement -Lets just say , from a $500 DAC to a $5000 DAC . 
@duckworp Thanks for your detailed and descriptive list. I recently upgraded my speaker cable. My DAC cord is decent but not great. I need to install dedicated electrical lines before doing much more with power cord trials. My AP Crystal interconnects really advanced the sound for me.

Don't fully understand the stuff about Cisco switch; have been using wifi rather than ethernet cable because I've read that ethernet cables are susceptible in real ways. I don't really understand #10. I have a comcast/xfinity router within a few feet of my streamer. Are you suggesting different kind of cord here or some larger scale change.

Thanks again for your answers. Good to know that writing up a ranked list is a rational think to ask.
