I have to say that at first I was very skeptical of another cable company claiming this and that, but I bought the Maestro 1 M IC about 3 months ago and I am using it between my CD player, Sony 9000ES, and tube preamp. It's astonishing how much the sound changed when I first plugged in the Maestros. There was a depth and dimension to the soundstage that I had never experienced before. The imaging was also extraordinarily real and believable. I compared the Maestros to cardas GC and golden reference. The Cardas Golden refrence was close but compressed the dynamics and presents a more veiled soundstage with unsatisfactory imaging. The Cardas GC was no match to the Maestros. I have also compared them to Harmonic Tech silver IC and Harmonis techs sounded bright and unbearable with a "flat"/2-dimensional soundsateg. I like the Maestros because they sound so natural. It really feels like a string being plucked or a piano note being struck. It makes me feel more and moer like I am not listening to a reproduction. My amp is a Classe Ca 150. I have been thinking about buying KAS Primus as well and I was wondering if anyone here had any experience with this PC. I love the maestro and IMHO consider them a bargain relative to what else i have heard. Cheers
