I haven't seen you state whether you live in a house or apt or condo. Neighbors?
Permanent residence? This will severely restrict you system choices. Unless, of course it really is female vocalists. I think you'll find as you build a really nice system you WILL play it louder...because you can!
If you are planning on continuing on this journey I would advise find the type of speaker you really like and then get the best of that ilk you can afford. Then treat the room, then find the proper power amp(s). Then source components and cabling. My mantra is build it backwards.
I intentionally left out dedicated power because we don't know your housing situation.
