Too much effort to rank, and for me it’s better only as a checklist as what one needs to address (or not) in their own system.
Waste of time to rank. To know what needs attention, different story.
Everything needs attention. Every tiny little thing. For example, take just one thing: the speaker. Tweaks that will improve a speaker.
Vibration control: Put on springs, Pods, Bars, or Podiums. TA-102 fO.q tape: use on the basket, as a mounting gasket, between mounting screws and driver, on the crossover board, on the caps. Put crossover on springs or Pods. Move crossover outboard.
Field control: contact cleaners and enhancers, NPS1260 (TC if you have it, and count yourself lucky if you do!), move crossover outboard.
Acoustic control: Synergistic HFT Speaker Kit.
Again, this is just the tweaks we can do on the speaker itself.
This same approach applies across the board. A lot of these same things work just as well inside an amp or phono stage or preamp or DAC.
Once you get the hang of this the opportunities are endless. My system is about as tweaked as you will find. Yet I have way more ideas for improvement than time to do them in.
