Cables are certainly system dependent. I can hear differences in cables but it takes time to decide if the differences are an improvement. I am glad to read you received good customer service.

I either need to solder the wires on one lug at the amp end or buy a banana that will clamp on both lugs for my bi wire pair. I was listening and one lug came off the amps terminal. All of a sudden no midrange or treble in one speaker. Fearing a short I am back to the AQ's until I create a solution so I only have one lug under each terminal.

I think the clarity of the AntiCables helped me hear the distortion that was building and indicated my amp needed repair.

No wire is perfect but the AntiCables are great for their price. My only very minimal criticism is I hear a reduction in instrumental textures. When I put some of my stranded cables in the system I hear more space and air but the sound is less focused. On some recordings I hear almost what I would call ghost images. I like the more focused soundstage.
