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


Although I have changed my system substantially in recent years, I still retain both speaker cables and interconnects that I have owned for ~15 years. I use Audience Au24E speaker cables and RCA interconnects, and a Virtual Dynamic David XLR between my DAC and integrated amp.

The system sounds very good, and I am not inclined to make any changes to the cables. Having said that, though, if anyone has used similar cables and found big steps forward without breaking the bank, I'd be interested to read about your experiences.

More broadly, I would enjoy hearing about cables that other members have stuck with for years.

I think the newest cables in my den system are at least 15 years old.  I finally threw out a pair of 1m Fulton Gold speaker cables that were languishing in my garage; probably around 40 years old.  Always a pain in the ass to use, as they were so stiff, and the plastic covering did nothing but deteriorate into a sticky mess over the years.  Still have a bunch of Fulton Brown (same vintage) sitting in my misc cable bin.
I’ve monoblocs beside my speakers so the cables are only 2’ long. 14 gauge solid core UP-OCC in Teflon insulation. I replaced home-made ones four years ago using a pair of wires from CAT6 in parallel with loosely-twisted 14g Romex wires. I’m a fan of solid core on speakers. The OCC wire is excellent with superb clarity, speed and transparency. 
I had an audio dealer over here for a listen.  Of course, he was looking for things he thought he could sell me to improve my system.  When he walked over and saw my 19 year-old speaker cables, he kinda stepped back in reverence.  "Those....  those are good." 
Yup, old cables.  Got off the merry-go-round quite some time ago; there's too much music to listen to.  Some Gabriel Gold Revelation R ICs, Argent Audio Pursang S, and Clear Day double shotgun speaker cables.  I'm a solid core kind of guy, aside from power (Triode Wire Labs and LessLoss).  The only new cable I'm sorely tempted to try are the Silversmith Fidelium speaker cables.
