Who else is using old cables/interconnects, and is happy?

A representative inside of McIntosh factory once told me that the engineers there maintained that there was no noticeable difference in various interconnects and speaker wire. At the time I had the Mac 1000t pre and 2102 amp.
 An audio reviewer who was a personal friend demonstrated otherwise in his system. That's when I first started to think that McIntosh was not transparent enough in its presentation to reveal differences. After trying other manufacturers products, I came to realize that the  comforting smooth sound of McIntosh came from a scrim over the presentation that obscures much micro detail. Well, I sold the Mac system and from that day forward have heard the difference in virtually all of the ICs I have owned since.

I'm skeptical though that cables matter much

Well @tk21, with so many cable companies selling direct these days with generous trial periods it’s certainly not too hard to find out if you’re right, so why not try?  You might be surprised.   

I still have my original speaker cables and they seem to be working great attached to my Apogee Duaetta Signatures. They are biwired by Temporal Continuum speaker wires   and guys  both of them are 29 years old.

I have stuck with my Kimber KCAG silver interconnects since the late 90's. Same goes for my double runs of Dynaudio OCOS speaker cables. So close to 25 years of use and I look forward to another 25 years. Really happy with my cables.

I see a lot of people in this thread who are using older cables and happy with their performance, but no one who can explain whether cable performance degrades with age, or whether current cable technology performs audibly better for a comparable investment and is worth upgrading to get.  Can anyone answer those questions? Thanks!
