Yeah I hope you do get top dollar on them. Oh you got the Maple/Silver ones? That should sell for more b/c they're kinda hard to find now since yeah, Meze discontinued that model.
How did you get the larger (white) pads for the Maple/Silver one? I'd read they only made the smaller (original) pads in that color for that model.
Well within the $300-$500 price range the only ones I could think of that I'd suggest you look into are the
Mitchell and Johnson MJ2 Portable Electrostatic Headphones, which are made in London. They are like electrostatic headphones but they are combined with cone drivers (aka "hybrid electrostats"), so they don't have the high power requirements that electrostatic headphones do, but offer the same high level of clarity. I've never tried them, but am interested to, one day. They seem pretty well-rated in both
online reviews and here on
Head-Fi. I would say they're AT least worth checking out as they also have wooden ear cups, and they are closed-back low-impedance headphones as well. One Head-Fi'er from that thread mentioned to me that the soundstage isn't vast, but that he felt what it lacked in soundstage it added back in greater detail than he's ever heard from headphones.
You can buy them on (U.S.) Amazon
here. Let us know what you get when you do and how it compares to the 99 Cs.
Good luck!
