Unlike dynamics, orthos don't suffer from impedance mismatching problems.

I still would stray away from using any of the HiFiMan ortho's with either the Auditor/Phonitor. Those amps have an output impedance of 10Ohms and can eb used with headphones at 80Ohms or higher. Remember output impedance multiplied by 10. Both amps are more aimed for high voltage output rather than current. That's why they clip really fast with low impedance loads. They struggle to output the current required. All HiFiMan orthos, except the HE-400, are low sensitivity and low impedance. They need a lot of current for them to sound good. 
 
Anyways I'll be posoting new pics soon for my set-up. Oh and my Soul Reaver headphone stand is kind of on hold right now. Too much going on in my life to work on it at the moment.

Exactly...damping factors and orthos are really a concern. kwkarth mentioned this a while ago and my personal experiences have confirmed it. Heck, even on my WA22, I prefer the high output impedance setting with my LCD-3s. But for dynamics, the low impedance setting works quite a bit better.

Realy? Heck you learn something new all the time. I'm a dynamic headphone man and thought it applied to both.

Ham on rye is great but tales of ordinary madness is great. I prefer his short story collections over his novels.

I never understood this.
 
Planars don't have physical movement that needs to be dampened, but they still present an electrical load to the amp, which can affect frequency response.
 
Is this correct?

But the load across the frequency spectrum is flat with orthos...quite different from most regular dynamics:

So if the load is flat, and mechanical dampening isn't an issue, then output impedance doesn't matter?

That's backwards.  Planar magnetics need lots of mechanical and acoustic damping.  There has to be so much of it that it usually seems to make differences caused by electrical damping unimportant.
 
Planars are also almost completely resistive loads with an impedance that doesn't change over the audio band so the FR isn't affected either.

Thanks for the info, guys.

 

[Rawrbington]

do they still cause power loss with a low impedance can and high output impedance?

Most dynamics don't fluctuate as bad as the hd800...

Pretty much all of the higher end Senns and Beyers do that to some degree though.
 
Also, a little zoom will show the differences more clearly since Headroom's scale on the impedance graphs is a huge compromise.

my WA2 doesn't have enough power for the LCD-2, i'm sure even though they can tolerate impedance mismatching more, they still need enough power, something my otl can't give my lower impedance LCD-2
