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.

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.
Don’t feel higher cost is needed to have a great listening environment. My last and current set up cost a mere fraction of the previous setups 
this one superseded the others by far 

No opinion can be ventured without an overall budget. Can you spend $10K?  Credible products are available in each area for $2K to $3K. If that’s a stretch are you handy?  DIY options are out there. Don’t neglect your room furnishings and speaker placement.
