What is proper ratio of money spent on amp/preamp/integrated vs speakers? 1:1?


Lately I'm finding more of a difference in SQ as a move up the chain in the amp/preamp/integrated market and not so much if I try to upgrade speakers.  Plus, buying and selling (and shipping) speakers is a PITA.  But having just upgraded from Devialet D200 to the dual mono D400 and loving it, it feels odd having $8000 (I'm in the used market almost exclusively) worth of power running $4000 worth of speakers, Dynaudio Contour 30's. 

I'm now wanting to upgrade again to the Expert Pro 440, but then we're taking about $10,000 and even more of a skewed ratio.
What is the proper ratio?  Thoughts?

Your question in its most basic form comes down to:
Should I spend less or more on something simply because I spent more or less on something else?

If that sounds silly, its because it is.

Buy [fill in type of component here] you love and can afford. Period.
Thanks all for the responses!  

Millercarbon - I get your point and perhaps using $$$ as the base of my question was the wrong approach.  

But I think we can all agree it would be silly to have Magicos driven by a generic Best Buy receiver or conversely Pass XS separates driving satellite speakers made of particle board. 

My query was trying to find that balance of when to upgrade what as my personal opinion is the power is making a bigger difference to my ears right now. 

Thanks again for the thoughts. 
Spend what you must to get the performance you expect with the value that suits your budget. Not every solution is for everyone. That’s why some prefer brand-new boutique gear, some prefer vintage, and some prefer waiting it out for the stars to align. Do what makes you reasonably happy. Life is too short.

Like @pokey77 said it’s about synergy. But yes its also stupid IMO to drive Magicos with a Best Buy receiver per @mjmcubfn. It’s a matter of what budget you have for your system and how can you build it so that it’s all of similar quality so that you don’t run really expensive sources through crummy preamps and amps and not hear how great your source is. Also you want to have speakers to match the quality of your upstream components. You want them to be able to play the quality they are being fed. There needs to be a balance. But IMO cable and power management is very important and you (if it was me, having proved it to myself) will want to spend some of the budget on quality power conditioning and the like, cables and interconnects. It make a difference and will enable you to hear the best that your system has to give.
