EnKlein Aeros. TWO 10-ft-long pairs RCA & XLR Get Ready for HiFi Fun!

Looking to trade for Shorter Audience AU24 cables. Let me know what you have, please.
Here's TWO 10-foot-long pairs of Enklein Aeros Interconnect cables. (Do some googling!)
One pair has RCA terminations, and the other has XLR terminations.
Light use in a zillion-dollar system in a dedicated listening room in a Westport, CT mansion. (Not my mansion. I don't live in a mansion.) There was no smoking in the mansion. No pets. No smoking pets either.
According to the Absolute Sound review, "Pricing of $6200 (1 meter and $3100 each additional meter)."  Seems astounding, but does that mean a 10-ft-long run would cost $12,400. Two pairs for $24,800?
I realize that I am asking a lot for these cables. Please feel free to make me an offer that I can live with.

Please take a look at the high resolution photos and ask any and all questions. And please take a look at my impeccable, 100%-positive feedback here and on all the audio sites. I always tell it like it is, and I never, ever sell junk.
FREE CONUS USPS priority mail shipping at my listing price. International buyers must pay for shipping and paypal fees, and no, I will not declare a lessor value for custom tariff;  it's up to you to figure out a way to bilk your country.

Local pick up is always welcome. Bring a stack of hundreds and your mask!

Stay healthy.
Thank you
