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

Someone finally got me to try better cables and my sound quality jumped. It jumped again when I spent $500 on used $1,200 cables and jumped again at $900 for used $2,200 cables
Actually, "Someone finally got me to try different cables and my sound quality changed. It changed again when I spent $500 on used $1,200 cables and changed again at $900 for used $2,200 cables."

The perception as an improvement is confirmation bias.

That’s a common knee-jerk reaction from someone who fancies himself a thoughtful cynic. But the explanation clearly doesn’t apply in this instance, where the listener had been convinced that - logically - there was no value in better cables:
the Mogami argument is perfect logic and caused me to outfit with them when I could have afforded better cables. Taking that and other “logical” approachs kept me in mid-fi for longer than I wished.

That’s very true. If you don’t know what you’re listening to. Besides, if confirmation bias actually improves the sound I’ll take two. 🤗

There is value in better cables that are well mated to a system.

McManus gave no inkling as to manner of improvement, but just that he had scored savings purchasing used. Did he audition anything or just grab a deal? What specific problem was he trying to solve? You and I may disagree completely with his choices.

There is very close to ZERO relationship between cost and performance.

Cables must match the system, room and user preferences - assuming the user is has some credibility and skill.
