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

Some of my cables are older - 11 year old Clear Day speaker cables in both systems, a couple of 7 year old Audio Art Cable power cords, Silnote Audio Orion RCA 8 years & Poseidon 2 digital cable 10 years

Thanks guys – keep 'em coming!

I have kept original Purist Colossus fluid speaker cables for 20 years, along with the same speakers. Feel no need to replace them until I upgrade the speakers. I have changed all the rest cables and cords with excellent results.

Started building an entirely new system (components + speakers) a couple years ago and only brought all power cords from the prior system. I needed a balanced IC and AES interconnect for the new system and went with Nordost Heimdall 2.

The power cords I was using from my prior system were all PS Audio P3 or P5s with the exception of a bottom of the line Shunyata PC on the Hydra 6 power conditioner. Upgraded all PCs and achieved nice results. Most recently I replaced two of the newer PCs with Audio Envy PCs, one is a P2 and the other is an M3 model. They are significantly better than the Isotek Optimum cables they replaced. Very good value proposition here.

In my case, the PS Audio power cords were not that good, so it was easy to improve on them. The fact that the AE power cords were an even larger step up over the newer cords demonstrates their value in my system. I will be buying more AE cables once I've settled a few things in my system.

I use Shunyata Copperhead and Diamondback power cords that were 15 years old when I bought them used here.  I have no idea how old they actually are.  As far as I am concerned, they are good enough and will not be changed.
