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.

Speaker amp match is critical
dont skimp on power 
call manufacturer of amplifier to discuss speakers
that is what I did and it worked

been  been using separates fir 50 years
just went integrated 
so happy!
Don’t be fooled by high price
some superb gear out now for little compared to the past
consider Classic D amp- on my second and thrilled and the room does not cook!
I had B&W 801 model 80 speakers from 1980. I used GAS Ampzilla, Ampzilla II, Hafler, Marsh 200c, Aragon 4004 II, and lastly a Denafrips Thallo 120w amp. The last amp made me regret all the years I wasted with the other amps. Spend as much money as you can because it will be amortized over many years.
My recs
Peachtree Nova 150 ( 150 for 8 and 250 watts for 4 ohms) clean power 
Great  sound stage!
I am using a pair of Elac 2,0/6.2 bookshelf speakers designed by Andrew Jones and are unreal for the price- Jones designed for TAD Pioneer etc
These speakers can go forever with great bass clean ,upper end  zero zero fatigue!

pure enjoyment - not fatigue!!!!!

You want to make sure that you don't get a bright or harsh amp, unless you like that sort of thing.  A  bright, let's just call it headache inducing, amp can ruin the sound of your system.
