How much does power amplifier really matter comparing to other hi-fi components?


What is the best ratio (out of a total of 100%) in terms of money to put in a high-end hi-fi set containing:
1. CD player/DAC, 2. Pre-amp, 3. Power-amp, 4. speakers.
(25% will be assigned to each if the 4 parts are equal).
Can we take this as a reference to distribute the budget when buying power-amp?

Looking forward to learning experiences and technical information from audiophiles including hi-fi dealers.

TAS Robert Harley’s book “The Complete Guide To High-End Audio v6” book has an budget example of 36% speakers, 50% amplification+DAC, 9% power conditioner, and 5% interconnects+ cables.  But these percentages are not set in stone- you may get a great deal or discount or may want to pay premium for desired component.  But maybe having a place to start vs no clue is a good thing.
Spend most on speakers, speakers make the greatest difference IMO. Amps have ruler flat responses and almost immeasurably low distortion. 

 If your power amp has volume controls, try as an experiment by-passing your pre-amp. Plugging in for example your CD output into your power amp, with your power amp turned down - of course). See what difference your pre-amp makes.
