Since you like both music and movies you could keep what you have and perhaps try different speakers, get a streamer like people have mentioned.
You could also look at a preamp with Home Theater bypass. I have a full home theater setup for movies but like music just as much. I was considering getting a additional system just for 2 channel music but another option would be a preamp with HT bypass. That way I can combine both systems.
If you are able you might try connecting your receiver and computer via network cable and then try your music through HEOS, you might notice a improvement in sound quality.
Also I would personally try one new component at a time, that way you will be able to see how much of a difference it makes. That is a little hard to do when adding 2-3 new items at a time.
