speaker and interconnects, how nice do I need


I am putting a system together, It is a NAD c356bee integrated amp, dynaudio x14 bookshelf speakers, and Marantz sa8005 cd player.  I put this together used for 2000, so I don't really want to spend another 2000 on cables.  What level of cables matches the level of components, I was hoping to stay under 200 for the pair of interconnects and speaker cables, so @ 100 each, is this possible.  Is my system still on the economical side to the point that it does not matter much, or will I notice a big difference between cables. 
thanks

I use speaker cables that cost new as much as my speakers ! Bought then used for 30%. And my interconnects cost half as much as my cd player, again got them used for about 30%.
Audioquest Type 4 speakers cables and King Cobra interconnects can be found at your budget. Look at Audio Advisor. 
Forgot to mention, I think you have put together a fine system. I heard and thought the X12s to be great. Read the X14s are an improvement and easier to drive.
Check out the Cerious Technologies thread that I started. Low cost extremely high value.
In any case, buy used cables here or on some other website. Cables are like new cars. Their value drops dramatically once they are used.
