My feeling is that the need for moar powah is overstated on these forums. I have some beefy amps, but I can listen to my HE-500s through my little Leckerton amp quite happily, they sound gorgeous. And I'm fairly certain that something simple and humble like the X3 / E12 will drive the Mad Dogs just fine. I believe MrSpeakers posted recently that the Mad Dogs sounded great straight out of an iPhone 5S. Sure if you pump in a few more watts/volts at home you might eke out a sliver of more performance, but when you're out and about I doubt you'd ever notice those subtleties.
My only concern for portable use is bulk and getting a decent case.
I see your point, but to me they equal a lot of open cans when amped properly. I have a pair of HE-500's on rental and I much prefer the Mad Dog right now, in various set-ups/listening conditions (I find the Dogs are more comfortable as well, no small consideration...The Audeze's aren't even up for consideration to me because of their fit) And while it's not an HD-800, I find it compliments that headphone nicely, with more of a different sound than a noticable drop in quality (small room good acoustics vs giant room and massive soundstage). Which beefy amps do you have onhand, jw?
And no, I'm not talking a "sliver of performance", I'm talking about it sounding like a whole new headphone depending on the amp and depending on how much power its fed. And most of that is centered on the bass performance. Lyr and Mad Dog is not a perfect pairing by any means, but it's a BIG, warm, lush musical sound that makes hours go by and while Magni isn't nearly as smooth, it's still a massive, near-openback sound.
Also not a knock on Mr Speakers (more on Fostex), but I don't find the design to be sturdy enough for portable abuse. They don't feel like they'd hold up being thrown in a backpack, lugged around, pulled out constantly, etc. I guess that's my one, lone issue with the Mad Dogs...Fostex's original build.
