the 10 ohm output wont effect planar magnetics much at all.

I don't think that's 100% true. AFAIK, damping factor may affect diaphragm control aswell other than the FR curve(which is what doesn't change on planars)

That said, I think E09k does a good job of driving the HE-400s.

It won't affect diaphragm control with planars. Can explain to you later when I'm back home.

Eric_C:  
Yea I have used the eq on the e17 and it does a nice job, but when docked with the e09k I use the lo-bypass pure dac function. when the e17 is docked like this all functions other than dac are turned off. also it is just a bit of a hassle to change the eq because I am constantly changing between my d600 ,he400, and q701. I know this is an extremely lazy reason to complain but...lol.
 
kenshinhimura & Okamoto Thanks for the advice, I didn't notice much of a difference between e17 alone vs fiio combo but I just wanted to get the most out of my He-400. These are my first orthos so not sure of much about them.
 
Davidsh I am lokking forward to your breakdown of what will happen with the diaphragm control!

hello to all , I have my own hifiman he 400 now... after i have read all this page.... I must said that i am completely satisfied and pleased.......I want to thanks all of you for the impressions and remarks.. I want to tell a great thanks for Justin of Headamp...... Very swift and very intelligent services..... I have an Aune T1 tube-dac/amp (with a bugle boy tube) and its a marvellous sound with the hifiman he 400......A satisfied canuck said Hi! to all

Really? Always thought poor damping factor degraded SQ in any kind of design...

All I know is my HE-400 had way better finesse out of O2 and Magni compared to my Little Dot MKII.

 

[reiserFS]

That's a given, the LD amps measure really horrible compared to the O2. At least the lower end LD amps.

Any reports on the HE400 with tube amps? Does it smooth teh tizz?

The tizz is somewhat smoothed out by my Bravo Audio Ocean amp. The Mullard valve I put in it also helps bloom out the mids a touch.

A few members have used the Aune T1 with their HE-400s.  I'm not sure which members are, but it was indicated 3 or 4 months back.  There's an Aune T1 in the FS thread for about $170.00.  It has a DAC built into it, too.
 
Edit: I also see that the F/S forum has Aune T1 (in silver) for $140 + shipping.

Hi all! I just got the he400 after giving up on the hd650 due to lack of a snappy bass. 
 
anyways, I'm currently running a e09k/e17 combo, but I've read (from NwAVguy) tbat the output impedance of the amp should be less than 1/8th the headphone impedance.
 
In this case the 35ohm impedance of this headphone is too low for the 10 ohm impedance of the e09k. Is this 1/8th rule the same for planars or am I good to go with the e09k? 

 

[mogulmaster]

Sorry for asking this again, I've looked and found opposing answers. can't figure out definitive answer

 

[davidsh]

Will explain tomorrow. Short answer: damping factor should not affect planars much at all.

And where did you find these measurements?

Just wanted to pop in here to report that the 400's being driven off of a Fiio E7 then through a Zo 1 on the first bass boost setting is just sublime.  I am a bit of a basshead, so I need a bass boost for almost all phones. This combination is just so good. So much detail and pounding bass for EDM. I will also say classical sounds outstanding as well...like I am no longer wearing headphones, but listing to my home speakers.
