Hi Steve. Thanks for reaching out. I’m thrilled that you are still enjoying the speaker cables. Both the XLR and RCA interconnect cables are ready though, as you noticed, they are not yet on the website. I’m in the process of finding an assembler to make these for me. In the meantime, I am making a small number myself for those who are aware and contact me directly. Prices are the same for RCA and XLR and start at $925 for 2ft. The common 3ft set is $975 and lengths are available up to 30ft. The connectors for both are minimalistic, with hollow pins made from alloys that are far superior to pure copper or silver. Mathematically, the IC foils are about 20% better than the speaker cable foils.
