Dumb question #643: should speaker cables last a lifetime?

The Zu are well made cables and should be good for many years.
A lifetime (now about 80 years) might be pushing it. Heck, by the time that happens we probably will have speaker implants in our heads.

"@stereo5 shadorne has been posting here an awfully long time I am certain his post was tongue in cheek." I see that now he has something like 5K+ posts. In that case, I stand corrected. I’m was reading it on my iPhone and it didn’t show the number of posts. My apologies to shadorne. It did sound awful fishy, lol.

aberyclark-

I am a "cable" guy, first and foremost. This is the forgotten component by many. No doubt that the technology and materials change profoundly every 10 years or so.  To answer your query- yes cables can a lifetime. After 20 years will there be a significant update? Yes as well. At some point in the future your gear will sound dated no matter how good it was brand new.
Cabling will age and/or sound dated too.

2nd note;

there are no dumb question(s) regarding Cabling.  Happy Listening!
