ok. i am looking to make my setup sound a bit better for as little money as possible because i dont have much to spend. i would say somewhere around $300CAD or so. i know its not much to work with so im not expecting much. here is what i currently have.

Paradigm Atom bookshelf speakers
Paradigm PDR-10 sub
an old Yamaha RX-530 stereo receiver
an even older Yamaha CDX-410U cd player
my speakers are connected with some good old cheap radioshack speaker wire (cant remember what gauge. i think 14.) and my sub is connected using the line level inputs from me receiver's outputs because it doesnt have an output for a sub.

so, what to do. i was thinking of getting a better cd player because your sound is only as good as your source. the other option would be a newer stereo receiver, probably used so i could get more bang for my buck (one preferrably with an output for a sub), but im not sure i could find much for $300, even used.

what do you guys think i should do?
