Is there a magic formula for spending on components in a system


Hello to all...

I'm looking for opinions on the magic formula for purchasing components base on catergories:

Source or sources

Control

Amplification

Sound Transmission

Interconnection and Cabling

Setup and storage

Thoughts? Opinions? Your system "equation" ?

PS: which of the above is the most important block in the wall?

I prefer magic stuff to idiotic ramblings tough....Especially when it is against others and in their back.....
There is no magic formula. Theres advice from fellow music loving enthusiasts. But I don't  believe in spending alot of your resources on cables.But that's my feelings. 
Many tell the tale of the magic formula. It is said it is buried high in the Andes, or maybe in the deepest Amazon, then again quite possibly on Mt Doom, in any case you will know you are close when you trip over a unicorn and fall into the Fountain of Youth.
