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

Hi,
Some of my IC on RCA where made by me some time ago using Belden 8402 and some switchcraft plugs, and sider with 4% silver. For
me they are ver musical and I enjoy what they bring to the table.

Cardas "Golden Reference" interconnects for sources.
Audioquest "Oak" speaker cables (pain in the but to deal with) 9 gauge. But man do they sound great!
Cerious Technologies "Graphene Extreme" power cords throuout.
Anthem STR amp
Ayre C-5XE MP CD player 
Oppo BDP-105  Universal  player
Nakamichi DR-3 cassette deck
ATC SCM 40 Studio Monitors 
Everything plugged into a PS Audio Perfect Wave Power Plant.
This combo works very well with My system 😎🍻 

I find it hard to believe ANY cable is worth more than a couple hundred bucks a set depending on the run.  $1-$4k?  Unbelievable!
 I have some 25 year old heavy monster cable and my system sings!

Most of my interconnects are at least 30 years old. These include Purist Aqeous, Tara Labs Analogue Standard, Cardas Twinlink and Audioquest Emerald hyperlitz. I no longer need 4 sets of ICs, but I still use the Purist and the Tara. The Purist were bought when the company was just starting out, and Jim Aud came and gave a presentation at a small shop nearby in Massachusetts. These are the original ones with the clear jackets, and 30 years later they have not lost any fluid and still sound fantastic. The Tara were marketed as specific for phono, and I have some new Cardas Iridium Phono on the way for comparison. The rca plating is wearing off on the Tara, otherwise I may not even have looked into replacing them. 

Forgot to add to my post above, bought speaker cables and interconnects used at 1/3  or less than the price of new.
Bonus is - they're already broken in!
