I have spent wildly different amounts depending on the system and have ultimately learned that it depends on so many factors, it is tough to come up with a definitive, rule of thumb. It will also depend on whether you are looking at floorstanding vs. standmount and sub speakers. You will likely spend more one floorstanders.
I am definitely of the opinion you start with your room, pick your speakers that fit the room and the look you want, then amplification and sources at the end. If you have a 12' x 12' room, you are not going to use a huge, floorstanding speakers.
That to me is the obvious way to go. I am going to end up with a wildly different system driving horns (Avantgarde) vs. cone and dome (Vivid / Wilson Benesch) vs Planar (Maggies) vs Omnidirection (MBL). I might use the same sources (DAC, Server, Turntable, Phono Stage) but I am not going to use the same amp to drive Maggies and Avantgardes.
Certain speakers only work in certain rooms. And, aesthetically, they can dominate a space the way other elements of a system do not. That is why I am always speaker first.
