I've got some and used them for a long while. After hearing Teo cables but baulking at the price I went on a mission to find something that out performed the Anticable XLRs and did most of what the Teos do. I came up short, the only cable I came across that offered a little more than the Anticable in my system was a top of the range Siltech at mega money and the owner admitted he'd struggle to pick between them blind.
None of the midprice options (and still expensive)like Supra/Siltech/Audio Note offered the transparency of the Anticables. Theres plenty of good stuff out there but the the Anticable offer is genuinely good compared to very expensive cables ime
