Flyin2jz, I'm offering a contrarian opinion: there is nothing wrong with your amplification and cd playback. Don't worry about it being "low-end". All the money in your bank account being spent on replacing that gear will not resolve the problem you are having.
"Soundstage" usually refers to the ability of a system to create the illusion that real musicians are in the room. The speakers need to "disappear". It's my opinion that those PSB speakers will not disappear: their conventional design fights against that happening. Point-source omni-directional speakers would be a better candidate.
Also, as pointed out by photon46, you need to do some dampening in the room: tame reflecting surfaces. You don't have to spend a lot of $ to do this.
Do what you can with the listening environment, and strongly consider replacing the speakers.
