I have a nice surround sound system. Here is my question. Would it be worth it to get a cheapo DVD player that can play cds and mp3s and has optical out so that I can hook it up to the optical in on my reciever? Would I notice any more quality over the rca cables that I currently have my portable CD player hooked up with? The big thing that I want is the ability to play mp3s on the system, I suppose I could always get a real long rca cable but i dont know if that would sound as good.
