You can definitely benefit from better gear, but you have to maintain domestic tranquility also. Very good sound can be had at the less expensive end of the audio spectrum and the law of diminishing returns holds true for audio gear big time.
It is very hard to tell what will sound really good to you in your listening environment. Unfortunately, reading about audio is not the best way to find out. Are you near an audio club or audio dealers? I advise you to try to find a way to listen to some better audio gear before you start buying.
One suggestion that I would make is to try to find some powered speakers that stream audio themselves or have a small streamer/dac that they work with. This is the direction that audio is heading and it will save you much expense (including not buying cds or lps) and headaches putting together a more complicated system.
