Reasonable high end interconnects: without breaking the bank


I am in the process of updating my audio equipment and have realized my interconnects are probably not up to snuff; I use the ones provided by the manufacturers.  My current set up includes a Leben cs600 amplifier, California audio lab Icon Mark II CD player, Linn Akurate Streamer, Feikert Volare Table and Spendor SP1 speakers ( in final stages of upgrade to either Audio Note E, Devore O93 or Joseph Profile).  I have been investigating interconnects and have a bit of sticker shock.  So any suggestions on interconnects that won't  bankrupt me?  Is silver truly preferable to copper with respect to resolution and detail?
Thanks

When I got back into this hobby about two years ago I started with the highest end Monoprice coaxials as my interconnects and SPDIFS. They are dirt cheap and did the initial job ok. I think for budget minded folks, I can say that Zu Audio on eBay is a good choice.  I have picked up some of them and have been please. Same with Surf Cables. I have also obtained other cables in the used audiophile markets, particularly Cardas and Shunyata. I think as a reliable baseline and source of cables Zu Audio is a good choice. The only thing is you will have to follow and win a bunch of auctions to get your stock together. 
Try Chord ,Kimber cable or basic Purist cables . The Chord cables from the Dealer in Austin Texas are the best cable for the $$$
