    The sensitivity of these headphones is quite high. At ERP, we measure around 106 dB/1mW. (Probably the most efficient Planar ever ?) We have tried it with several amps and most of them drive it well.

    if that measurement is accurate, then that claim of most sensitive planars is probably true as the PM-1s were previously characterized as the most sensitive planars at 102 dB/1mW. However, the Oppo's impedance is 32 ohms, so it would still probably be easier to drive.

    Headphone measurements are tricky. When a headphone is measured there are multiple points  (DRP – The drum reference point, EEP – The Ear Entrance Point and ERP – The Ear Reference point)  where you can measure the efficiency.
     
    At Audeze we have always quoted DRP and Oppo uses ERP, which is closer to the headphone. 
     
    LCD-X is probably a bit more efficient that Oppo PM-1 measured at the same point (ERP), compensated for impedance.

    1.2k ohm sounds sooo interesting indeed

    106 dB/1mW is very, very efficient I would say and I really like the new look!!
     
    I know it’s only a prototype, but is the sound sig more like the LCD 3, LCD X or something totally different in your opinion?

    interesting information. thank you

    100WPC @ 4 or 8 ohms?

    I wonder could the WA2 power this headphone and what it would be like through the DNA Stratus?

    Since planar have almost perfectly flat impedance response, you may already drive an LCD-X from a high Z-out OTL amp without altering frequency response...no ?

    What do you mean by high Z output ?
     
  12. Shazb0t
    Z is the symbol for impedance, these guys are getting on the bandwagon.
     
  13. richbass

    Oh. And the impedance is measured in Ohms. Correct?
     
  14. Rem0o
    Yup, but impedance has an amplitude AND phase, where resistance has no phase measure being the "real part" of impedance. To get resistance, you do cos(phase) * |impedance|.

    So can anyone please explain the question - Why would a higher impedance be an easier load to drive?
     
    These headphones sound too interesting to pass, though I'm using a tube amp atm, it would be interesting to see if I should continue with tubes or go solid state (Rag)
