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

So how many miles of Mogami microphone cable did the signal travel through on its' way to you? And Mogami is how many pennies per foot?
Fstein - 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. 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. Why other cables sound better, I don’t know ... and don’t really care any more. I’m just glad they do because I love it when my sound quality increases, its the thrill of this hobby. In so many ways it’s not a logical hobby. But I love it just the same. There are certainly exceptions but when you spend more you can get worthwhile improvements in every area of hifi. I wished I’d learned that much earlier instead of thinking that I was being clever by not trying the more expensive stuff. Just my experience.

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.

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:

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. 🤗
