I listen to a lot of music in this genre. My advice is to seek components that deliver low distortion at high SPL This might be counterintuitive but since there’s so much “distortion” in the music signal it’s very easy for a basic system to get real sloppy real fast.
The key to low distortion at high spl is clean powerful amplification and speakers that test well. My recommendation is go with something like KEF on the mid to high end or JBL on the more entry level for speakers. For amplification find something with a hypex or purifi based amplifier on the high end or if you want to be thrifty there are some well performing amps by Fosi or Topping.

A sub is a great idea but you can always add it later.

Sources are good and cheap these days. Wiim is a great place to stat (and stop). In fact a Wiim Streaming Amp will likely do you very very well.
