Start with speakers.
2 Years ago I started my journey...
Are you handy ? I followed a thread for 10+ years on a DIY speaker design.
Elsinore speakers. Many consider end game. Depending on how nuts you go, you should have 5-6K left. Speakers are 98db per watt, so 10W will pretty much blow the windows out.... Been told they go louder than anyone ever needs...
That said, I did a Tube amp (8-9 Usable watts) (love it) turntable and RPie/LMS streamer ..
Many folks who never heard music like this cant simply walk past the system... It draws most in, mouths gaping murmuring OMG, that sounds soooo very nice...
I figure that I'm still south of the 10k number. And I would spend double for the speakers if I had too.....
Good luck...
