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."

oregonpapa has a nice summary. Townshend springs, HFT, ECT, PHT, cable elevators have all made a huge difference. Haven’t yet tried fuses, tube dampers, or PPT. Those tweaks are on the agenda.
Definitely it's getting the room and speaker placement correct, best using a laser tool. Then isolation of components especially a TT if you're into vinyl or your CDP/transport. From there power is next like receptacles. Then just too many others but get the foundation right and things will fall into a happy and enjoyable listening experience.
Component isolation makes a huge positive difference. Power cords and finding just the right digital cables seem to set the foundation for choosing ics and speaker cables.

no experience with fuses,risers,or changing out caps.
I don't have a room dedicated to audio. Also, I'm very constrained re: speaker placement.  

RE: cables, I've upgraded to all my components but found that upgrading amp and digital cables has had greatest impact. 

I've tried a variety of footers and while they all had some small effect (good, bad, or indifferent) the vibration approach that's had the most noticeable and positive impact in my system has been Symposium Svelte Plus Platforms coupled with Rollerblock Jr. +'s. 

YMMV
