+1 with Mapman, start by selecting speakers. Find something that "speaks" to you. I can recommend auditioning Janszens, either the zA2.1 or new stand mounted zA1.1 if you can find any near you, but there is a huge array of choices.
Speakers can determine room design. Are they best suited for traditional positioning 2' to 4' out from the front wall? Maybe dipoles better situated 5' + from the wall. Or the currently more rare against the wall or even in corner placement designs. Obviously which design type appeals to you should be established before beginning any room design.
Also, following speaker selection your search for amp(s) and then source components should begin to be focused down to fewer options.
Good luck.
