@hoping I agree that deciding on what speaker you prefer first is most important and being sure to pair it with an amp that's a good match. These two should take maybe 50-75% of your budget.
From the components mentioned, I'm guessing you are relying on youtube video reviews...which are limited in covering the range of what's out there. Do you have a chance to demo gear at stores, homes or shows before deciding? Speakers are all a matter of priorities and tradeoffs, so it makes it important to get a good sense of what matters most to you and if you can't demo, look for detailed descriptions of the characteristics of each contender from multiple experienced sources.
IF you've heard any systems that really sound great to you, describing what gear and what you loved about it may help people steer you towards items that have those same strengths.
Also, it takes great courage engaging in a non-native language. I applaud you and apologize for comments implying the flat earth ends at someone's borders. Cheers,
