I have the 2404 speakers cables and the top of line RCA I/Cs. I think these are superb cables and most importantly much of their cable "speak" makes perfect sense. Craftmanship is the best I have seen. I plan on upgrading to the 4004 speaker cables soon and getting a second pair of I/Cs. The only thing I dont like is that they use Rhodium plating. Visit their site and see what you think. You may be able to audition in your home.
