If you have the space and the money I would recommend you try a separates system for music alone. Keep your video gear for movies etc. apart from your music system.
Separates are the best way to achieve the best sound quality but it is anything but efficient. Nonetheless you can have a good time chasing that music nirvana we all lust for. If you want to try vinyl start with an inexpensive turntable. Other sources might be a server and disc player then through a preamp, to an amp, stereo or mono blocs, to your speakers. Start with an inexpensive cable loom from your favorite bargain cable manufacturer.
There you have it a separates system.
If you are flush buy whatever you like unconstrained by budget concerns.
(Then constantly upgrade and tweak your system)
