Charles that is a reasonable approach that helps clarify the pecking order of things and helps put things in perspective.
Minor tweaks are minor tweaks and only really of value once the big ones are addressed first.
I'd just hate for people to get the impression that audiophile fuses are the easy solution to fix whatever ails their setup. Maybe they are but only after many other things are in order first and also probably if the investment in dollars is such that a few hundred more for expensive fuses is not a problem.
After all as fuses go they ARE expensive. Way more so than most. I think that is hard to argue. But perhaps they are worth it once a big investment is made and now one wants to dot the i s and cross the t s.
Just because I have not seen the value so far or that others have does not assure the next guy of anything.
