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

Elizabeth nailed it. I use Anticables in my system. Very happy with the sound quality of their the speaker wire and ICs. My source is a LUMIN D1 using Tidal HiFi decoding MQA files. Power is from my Krell integrated amp (class A) thru Magnapans (1.7is). The anticables helped with the high end clarity and bass is tight. Buy what you can afford - we have too much choice in this hobby. Your ‘ear’ is the final judge.
I'm wondering if any of these recommendations would change if it was clear that the OP was going to use balanced (XLR) cables or was going to have a long run from pre-amp to amps.  I seem to remember that Elizabeth found the Cardas Parsec excellent at short lengths but not so at longer lengths (hence her purchase of the much more expensive Kimber cables).  Anyway, that's what I need: XLR cables at 5 or 6 meters to get from my stack of equipment to my mono-blocks, next to the speakers.  Using Morrow MA 4 right now, which isn't terrible, but I wonder if I can do better without going over $1000.

It might make a difference but since the original poster his/her amplifier is completely single ended, the xlr question is kindof moot in this case. If you want advice, start a thread, list your equipment and sit back and relax. Someone or several someones will likely have some suggestions.
Good point -- I hadn’t thought to check out the OP’s amp. Will start a thread.
