Moto: Because it does not sound the same. I have already experimented with the OTA plastic RCA's and (26) gage solid core silver and copper "quality wire" from other sources and cannot achieve the sound of this cable. I came up with one set of IC's using a pseudo air dialectic design, that sounded good, but after a few weeks listening concluded that they (though better to me than some pro IC's that I have used in the past) are not nearly as good as the stock OTA. The kit contains 50 meters of cable, by the way. Consider me an audio fascist if you must, by I tend to judge items by the end result (how they sound), not by how that sound is achieved and this stuff is apparently not your average run of the mill 26 gage Teflon insulated cable. So, for $600 I have enough cable to install speaker wire in two systems, plus have three sets of IC's at my disposal. The fact that both the IC's and the speaker cable are by far the best sounding that I have ever used, makes it a frugal purchase I would say. I will still play around with different IC designs, because it is cheap fun and I figure that I can't burn down the house doing so. Anyway, give it a try and see what you come up with. Oh, and I am pretty sure that the copper wire is 26 gage, but am not positive.
