Sort out your room first (acoustics, treatment, mains, plug points, aerials for radio, points for Ethernet, cabling and ducting, decor, furnishings).
Then speakers (type, size, positioning, room nodes, power needs).
Then amp (minimum fuss, low maintenance, convenience of remote etc.)
But none of it in isolation as it’s all interdependent.
Then whatever sources you fancy.
Or accept that you like the hobby. So buy and sell and enjoy the journey shamelessly. Maybe work in hifi shops to listen to a load more kit. Or volunteer on a Saturday. Or form a club with friends to swap kit or group buy and pass round. And also accept you may have to go through a fair bit to be able to do the room-speakers-amp-sources stuff anyway.
But never forget the music comes first, listen to as much and as varied as you can from whichever sources make sense at the time. And revisit music periodically as it will constantly surprise you long term as your systems ebb and flow across time.
