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

1) Russel is a quack. It’s easy to hear differences in cables.

2) It’s time for Audiogon to make it impossible to add posts to threads that have been dormant for over 5 years. This 15 year old thread should have stayed dormant.
1 also under controlled conditions?
2 why? Does it trouble you that people are telling an uncomfortable truth?
