I attended the same show. I listened to the Ansuz Sort in several of their display systems. The technology behind the the Sortz reminds me of the Cardas caps that was the rage years ago. The Sortz costs about 800 and some change each! They said you only need one, but wait, obviously, two or more are always better. When they installed one of these RCA plugs into an unused plug, it changed the sound in some way. I would say it sounded more open. It was high res streaming so perhaps it does eliminate some stray EMI//RFI because it is designed to reduce spurious or stray signals that may find their way into the inputs of your device. I am interested to test these in my unused phono input as I see that as being the place where such stray electronic signals may have the most effect. I read the attached linked review and now I think it might be more something to experiment with than I must have. YMMV like many things. I left the show without taking any home,
