And the same Orthodynamic Transducer you can find,
on a Kawai SH-5 and Vector Scan VSH-5?
Thanks,

I posted this question in an old SE-500 thread, but I'm not sure anyone will notice so I thought I would post here too.
I have a question for those of you who own or have owned the SE-500. I just received a pair and I can't seem to drive them with any of my amps.
When I use them with my Oppo HA-2SE I don't even get any audio, just some odd popping noises. When I use my C&C BH2 I do get audio from both sides, but the left speaker starts to distort before it even get remotely close to the listening volume I typically listen at. Then, when I drive them via my Schiit Lyr (which I assume would have plenty of power to drive them) I have to turn the volume up to about 3:00 on the dial to get even close to an acceptable listening volume, albeit there is no distortion like there is with the C&C BH2.
So, my question is, am I not using the right equipment to drive them or is something wrong with them? From reading the old thread Takato mentioned that he was able to drive them via his iPhone to a degree so I would figured that the amps I am using would drive them even better.

these are made to be driven from a speaker amps leads
Sounds like they're faulty because you should be getting quiet music out of them at the very least.
Lyr should be able to make them sing really.
Have you checked cable integrity?
Yes true, but I would still think that the Lyr should be able to drive them since they produce 6W RMS per channel.
I have and could not determine any faults in the cable. Nothing in the audio changed while moving the cable connections around at either the plug or where they connect the earcup.
Do you think that the Lyr should work well with them simply due to the power it can produce or do you feel that even my portable amps should be producing greater volume as well?
My first thoughts is that they're faulty as well.
A DMM won't work, the piezos are a 100% capacitive load. This equates to roughly 10 ohms at 20kHz and 100,000 ohms at 20Hz -- the impedance listed earlier is not a spec of the headphone but a rated load impedance for the amplifier. You'd need a very expensive multimeter with variable frequency control to reliably measure the impedance of these, like Tyll's. My cheap DMM just kind of shrugs at me when I touch the terminals of my SE500's plug.
This is the result Tyll got from my SE-500.
