how much should you spend on cable?


how much does one spend on ic/speaker cable?(%of the entire system)?
let say hypothothetically if you system ( cd, preamp , amp, speaker ) cost 30000? what is a reasonable amount to spend on the ic/speaker cable? 10% 20% 30% or more?
how does my fellow audiophiles balance the equation in their system?
thanks

Reviving this thread in light of recent discussions here on cabling.  I am currently running two systems.  On my main system, investment in cables is about 20% based on retail prices.  On my secondary system my investment is closer to 40%.  In both cases, I think the cables are appropriate and have increased my enjoyment considerably.  Interested in your thoughts.
I don't even know but I guess I spent less than one percent. Anything more is a waste of money.
It's a little difficult to answer that question because I stopped using cables as well as interconnects and power cords a while back. But good luck with this thread anyway. 😀

There's that science claim again. 😩

A person with limited funds should buy the most expensive cable they can afford. 

There's more truth than humor in that statement. Think about it. 🤔

All the best,
