Start with speakers. Then orient addition purchases to support them. You want additional component to break in and drive your next purchase decision unless you are wealthy enough and sure enough of what you are doing to purchase the speakers and all the new components at one time.
But everything requires breaking. I am a big fan of Sonus Faber speakers. I am on my third set after exploring the world of planar for many decades. Very natural and musical. It can be really helpful to go listen to some really good systems of different flavors to get a feel for where you want to end up. Natural / musical, highly detailed / flashy imaging system, muscular system that slams you in the chest. Very different end points possible.
My endpoint rule of thumb is 35% speakers, 15% amp, 20% preamp (yes you still need one), 15% amp and 15% streamer. Wait to invest in high quality interconnects and wires until later. It’ll take you a year to really know your system. I’d consider DHLabs for interim speaker cables and interconnects.
