Planars don't care about output impedance.

Planars don't exhibit impedance variation with frequency is true because they are pure resistive loads. Dynamic drivers are highly reactive loads. This trait is responsible for perceived variation in frequency response and why dynamic drivers can have myriad of frequency responses based on amplifier's OI.

However, electrical damping is another thing and also for maximum power transfer to the load the OI of source should ideally be 0. I'm not complaining that Ananda had any unevenness in FR part from iHA6. I'm saying it sounded slow and bloated.

Thinking about picking one up 11.11 sales
If you only need single ended inputs and outputs, I recommend considering the Burson Fun with Sparkos SS3601s. I struggle to hear a difference between that and the H20 with Sparkos SS3602s. The stock opamps are meh, though. And my review unit had an occasional buzz that went away with power cycling or re-inserting headphones.

Wait, Are you saying the burson fun is at the same level as the h20?

With stock opamps in both, the H20 crushes it.
With Sparkos SS3601s (2x $40) in the Fun and SS3602s (2x $80) in the H20, and using the MrSpeakers Ether (C) Flow, I struggle to hear a difference, yes. Might be different with other headphones, I don't have any high impedance cans.
I know, I can hardly believe it, either.

I was under the impression the vivid and classic op amps were superior then the sparkos, have you tried those?

Not yet, but I'm supposed to get sent the Classic, for either the Bang, the Fun, or both (this is part of a review tour).
Where have you seen a comparison?

Where it's at...
I think that's pretty close to what I paid for mine. I haven't regretted it for a moment since. Wonderful amp...

Ditto to Zennheiser!!! i've had my h20 for about 6 months and could'nt be happier. I put the sparkos in mine and i felt it made an improvement. I have the burson op amps in my h10 and they too were an improvement over stock
