On paper the Audinst hud-mx1 and e09 should be the best, although I have not heard it for myself.

DAC/AMP for the HE-400 update.
So I'll get the latest version of the HE-400 within a month and I'm already trying/buying new dacs.
I bought the E17 as an upgrade for my E7, and dock it the E9.
Apparently the E17 sounds less good docked in the E9 than the E7. No need to say I'm returning the E17.
I recently bought the Audinst HUD-MX1. I'm wondering if the headphone out of the HUD-mx1 will be good enough to power the HE-400, or do I need to connect the HUD-MX1 to my E9? I think the later will do nicely
I bought the HUD-MX1 from the audinst ebay shop, which is located in Korea, so it will arive in about 4 weeks.
According to the specs I can see, the HUD-MX1 can provide 310 mA into a 32 Ohm load 12V power supply. We could do some calculations to guess its performance into higher impedance loads, but it is probably doing roughly 200 mA into 50 ohms, which is where I think the HE-400s actually spec.
This amounts to about 26 mWs max@32 Ohms, and say, 17 mWs max @ 50 Ohms. That should be enough for about 15dB over the 92-94dB/mW rating, so, plenty to get quite loud.
Unless I am way off, I would think it should run the headphones well under most conditions. But this would be far less power than offered by the Fiio amp.
Thanks for the calculations
So it can get quite loud, but it will not sound good right? Atleast this I had with a different usb-powered dac and my HD650. It could drive the HD650 really, really loud. But the sound quality wasn't there, no detail very bad bass etc.
Why is this exactly? Looks as if there is just not enough power available for those harder to get frequencies (bass). But it will run loud still because the ~ 1khz frequencies don't need as much power?
About to buy these headphones, but I thought I would ask a few questions first. I purchased HD650s during the sale and I almost don't want to give them away because they were such a great deal. I don't have them yet, but I've been reading about how the HE400s may be a better match to my music preferences.
I listen to a lot of theatrical scores (Hans Zimmer!), Ed Sheeran, Norah Jones, Taylor Swift type of music, and then there's the electronic side of me, listening to all kinds of dubstep. I tend to favor "fun" sounding headphones, but I also want to hear the warm details in acoustic strings and female vocals.
I will also be purchasing a dac/amp combo up to $300.
Based on this information, would the HE400s be a better fit? Or should I stick to the HD650s.
ALSO, I study a lot with my headphones on, and the heavy weight of the HE400s make me worry about facing down at my textbook. Has anyone ever had problems with the HE400s sliding off their head while facing down?
Thanks!
Just outta curiosity. What do you guys keep your HE-400's in when you want to carry them around?
The stock box really doesn't seem to be sturdy enough (thin cardboard)

It has nothing to do with power and everything to do with implementation. You can have oodles of power and a top tier chip but if the circuit design is crud the headphone will sound like crud. Something else to note, you can have a top tier pricey amp and one headphone can sound terrible while another will sound fantastic. It's called synergy, don't ask me why it happens it just does. If you're looking for a good mobile sized amp Leckerton and ALO have nice offerings. I own both of Leckertons amps as well as the ALO RX MK II and I'm quite happy with them. JDSLabs is another dealer you can look into. The O2 amp gets lots of praise on here.
