I bought the anti cables but don't care for them. If you need your treble tamed they would be good. I compared them to one meter lengths of Siltech Ribbon and Van den Hul Revelation Hybrid using long interconnects from my preamp and the result led me to buy some used Cardas for more money than I ever believed I'd spend on a peace of wire. I can't use short wires on my M3 so I couldn't use the short ones I had. I will grant you that the price differential is huge but anti cable claim to be competitive with the best. But if they have a money back guarantee what can you lose? Mine are going one way or another.
I have had Kimber 8TC, Nordost Red Dawn & Nordost SPM, and Cardas Golden Cross speaker cables in my system. Believe it or not, my system is now more musical than ever with Anti-cables. If I would have knowm this before, I could have saved myself a few thousand dollars.
You must try Anti-cables, you will not be disappointed!
As usual, lots of praise for the anti-cables. I've tried tons of cables at all price levels over the years. The anti-cables are perhaps the value king of cables, just be aware they they are not shielded. If you live in a high RFI, EMI environment they may not be best choice. This is especially true with tube equipment and speaker cable!
Beyond that cables are system dependent, any advice given may or may not work for you. I use Cardas Golden Reference throughout my system. I find them to be the chameleons of the cable industry, they don't stand out in any particular sonic category. This chameleon-like character makes them good cables to build around. Unfortunately, they are going to be around 1k in your length.
As for snake oil, don't believe that one until you try for yourself. Reference quality cables can make a difference, the problem with cables is the diminishing returns ratio is steep.
SNS et al. You are right that you must audition cables in your own system. There is nothing I've tried that's worse than Cardas in my system. ..and so it goes. It closed down the highs, diminished the dynamics, put lots of grain into the system..yuk. I called and spoke to Colleen who said they sounded not broken in....after a year I tossed them.
