Well, I took a look at the other site where there is a lot of equipment for sale.
There are two cables that might be worth considering. Both are about 15 years old, though. Both cost about 600 USD, I would try and take the price down by at least 15%. Both are 2.5 meters long.
1. Audience AU24.
2. Purist Audio Aqueous 20th Annivessary.
I have original Purist Audio Colossus fluid speaker cables. They are probably at least 30 years old, they sound excellent, and I have not upgraded speaker cables for 25 years ! I have upgraded RCA interconnects five or six times during 25 years.
