O.......one thing I may differ with dsnuts view is that I don't think the jvc fxz100 / 200 pair are at the same level as the cks1000. First I must stress that the fxz brothers differ in sound more than one may imagine. But then both got more engulfing bass than the cks while lacks sorely in the mids department when compared to the cks. This by itself is a deal breaker for me. Plus the overall refinement across the frequency range of the cks is a lot better. I've spent some quality time with all three and I don't really understand jvc's tuning. YMMV tho~
The FXZs has their charms. I like them quite a bit as well but these CKS1000 has been steadily growing on me ever since I got them. The sound is fantastic..Went into the CKS1000 purchase with an open mind to get a very nice sound from AT. My favorite AT earphone to date actually. I think they are a great buy especially when bought through Amazon Japan using Tenso.
