I got my Sextetts last evening. Boy they are quite nice. Upon a quick glance they look to be MP. I tried them with a few amps and the only amp that could do them justice was my Cavalli Compact Tube Hybrid. My other amps -- O2 and The Wire just don't have the voltage gain for these. I'll be building an EHHA Rev A. in the future that should work well.
So yes they are pretty much in excellent -- close to mint condition. Headband has no cracks. Pads are worn, but aren't worn out. Rubber bands are in great condition. I'm not sure if the inner foam ring is wearing out. Thus far nothing is coming out of the phones, so it's hard to tell. I'm going to have to open 'em up to find out I guess. Kinda would like to leave 'em alone though. I'm thinking of going at least for replacement pads and even the foam rings for good posture.
How do they sound? Yes they have really nice and lush mids. I can hear the graininess in the highs that people speak of. The bass seems a little boomy or wooly and not as controlled as I thought they'd be. I'm thinking the EHHA might take care of this. Overall, I think they're worth 140 bones.
Finally, what is different about the Cardan version?
