An alternative view on system balance - what to spend where

There have been many threads exploring different views on how much to spend on different parts of the system. Generally these tend to boil down to two camps either source loaded or speaker loaded with a sub argument on budget for cables generally in the range of 10-20% or so

One thing I keep track of in my pretty pricey six digit system (fully documented as "Small Room, Big Sound") is where I've spent money and I wonder if certainly as your system becomes sufficiently resolving the typical budget rules break down? In my case the surprise factor is that "tweaks" (cables, acoustic treatment, power conditioning etc) actually make up well over 50% of my budget. Now I'm sure I never planned things this way but my experience is that once you have some pretty good components then incremental money is best spent optimizing how they and the room work rather than jumping on and off a never ending escalator for the next best thing.  Sure I could have spent more than 10% of my entire system budget on speakers but Magico Q3s are actually pretty good, match the room well and as you tweak the hell out of them they sound better and better and better

So my modest proposal is, assuming you basically like what you have, consider devoting one or two years worth of upgrade funds to optimizing every bit you can, if and when you do upgrade a component the tweaks should still all be valid.  My current mission is managing vibration which in the past few months has included new footers (Marigo F8), Shunyata DFSS elevators for my main interconnect (a great improvement I just installed today) and on order the Townshend Seismic Platforms for my speakers (which I will report on when they come from the UK)

So my question to the room is how owe much of your system budget is spent outside the main components? And how much should be spent?
