Take a look at the KLE Innovations cables.
I've tried most of their cables and all of their RCA's and I haven't found anything that can compete, especially at the price.
I compared the gZero3 with a silver Kimber Kable XLR on a 50k system, and the gZero walked away the clear winner - in all repsects - especially the price $475 vs $1200 for the Kimber.
They perfrom extremely well on my modestly priced ($15k) system - elevating it's performance to a very high level
I have their latest gZero20 and it's pretty amazing, but then it should be for $1999 Aussie dollars.
The gZero3 are more dynamic, articulate, spacious and detailed with a clarity that will amaze, i.e. when compared to most other IC's in this price range.
If you are into looks - these cables are quite simply - very plain
I'm more performance oriented, so I don't care, because they perform.
Resale value? - still quite an unknown commodity - but then if they work as well as I've stated above - you won't be selling them :-)
