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 have a tube buffer passive preamp and upgraded to Mundorf oil caps.  Really like the sound.

Amp, preamp, streamer, DAC all have twisted pair power cords.  

Ethernet cable to streamer

Meticulous speaker placement.

Next up is isolation.  I can't afford Townsend podiums for speakers.  Isoacoustics, Herbie's are being considered.
Ive tried a bunch and you truly want to hear a differance and possibly its a placebo effect but the two tweeks I done and without a doubt knew it was better was changing out the patch cable 5e from my Router/gateway to my streamer Node2I to a Linkup Cat8 22guage for $34. then I would say I did notice an improvment when I made a DIY Mogami speaker cable it definitely had a more refined sound and I want to say the IFI acPurifier does help outside of that I had high hopes for others like iso acoustics solation pads , interconnects and a few others and it didn't really blow my skirt up. Im a huge believer in putting some money in the source streamer- upstream , Garbage in Garbage out . Im thinking about getting liner power supplies for my router and my streamer now and possibly a galvanic isolator for the ethernet  , maybe something was wrong with my old 5e patch all along who knows , Im moving on. 1 absolute must is acoustics , I wrapped my entire room with a track curtain that has sound deadening material and that without a doubt is the best thing you can do to remove echos and get more detail from your current setup. 
raulwebster Piped in at 3.45 am Zero Gravity chair and cannabis. I’ll assume both were in use. Late night dude!

Raulwebster’s comment hit me like the proverbial ton of bricks. I’m taking about the chair. Spot on. My chair is so-so. 

Also would like a class trip to the Millercarbon joint. Like wow. 
While upgrading componets ( external and internal ) generally give you better or more pleasing sound . Two tweeks that suprised me were replacing the weight on my Rega RB300 tonearm to an Expressimo that lowered the center of weight and replacing a PS Audio power outlet to
an AudioQuest NRG edison ( does this count as " electrical " ? ) .
One I tried didn't like were tube dampers .
