ArTiK_slaughterA very very delayed reply because I just happened to see if MD ever offered Stax.
No, 132KOhms is correct. These are electrostatic headphones. They require very minimal current <1mA but very high voltage >500V to drive. Some of the electrostatic amps on the market go all the way up to 1500V output. If you look at full electrostatic speakers, it's not uncommon to have drivers that can output >3KV at higher current. A regular coil speaker unit usually requires high current and low voltage to drive (<30V & >10mA).
EDIT: Voltage mentioned here are all VPP, not RMS.
