It seems that Bob and I share a taste in headphones. If that is an early set then I get his reaction, the modified 007 is just a far better transducer. This is especially true if you tend to listen at higher volume levels, that's where the 009 falls apart and the 007 just craves more power. The amp also can't be blamed here as the KGSS is on the warmer side of the spectrum. Me thinks Bob and Tyll could use a loaner amp to try out. Either a KGSSHV mini or a Carbon. The special KGSS Tyll has is great but both the HV and especially the Carbon just step it up a notch. The detail retrieval the Carbon can muster is just absurd...
