I have the Audio Magic Illusion power cord, and have auditioned the Teo Liquid SPDiF cable, and their RCA interconnects. I have many other cables to compare with, along with quite a few components of High End, Computer, Video, and a refurbished receiver (Sansui).
Overall, I have not been very impressed by any of the ones I have tried. I do get very good results with the Audio Magic Illusion (liquid), on a tuner I have here. For some reason, I am getting deeper bass from the tuner than the other high end cords I have, and also better than a good generic cord, fitted with Bybee Slipstream filters. So I am happy that I found a component that this cord works well on. The Illusion power cord also works well on Video screens, better than generic cords anyway, but my preference for video is cords with silver, or silver alloy. On other audio components, tubed, solid state, and digital, I get better results from other specialty cords.
The Teo Liquid interconnects and digital cable, were rather unspectacular, and slightly dull to me. This is only my opinion based on limited use. The prices for the Teo products were exorbitant to me, and therefore did not elicit good value. I have heard from other Audiophiles, that the Teo speaker cables are an excellent sounding product. Having heard them myself, at a show with Soundlab speakers, I have to agree. The sound was very clear and unfatiguing.
