I did not know that. If so that may be a reasonable course of action. 

I wouldn't expect such a tiny amp to be able to drive big planars properly... but it doesn't fully explain the distortion.

I spoke with AudioQuest. They gave me an RMA number. Seems I may have a defective unit. I'm still planning to buy mini-X and really give these headphones some juice.

You don't want to use the mini-x with the he-400, they're too sensitive.  I think you're overestimating how hard it is to drive it.  If you simply want power for cheap just buy a Schiit Magni.

You might be able to use the mini-x if you lower the volume digitally, but it does seem like overkill. People on the mini-x thread are reporting that they have the volume at 9 o clock on the he-500, which is less sensitive than the he-400. Most amps that plug into the wall should be able to drive the he-400 just fine. Lots of he-400 owners use the magni or o2.

All you really need is 9 o'clock on the Magni for the HE-400.  It has that 1 watt of power AND it has a fixed gain of 14db.  I can only imagine that you'd have a hair of play on the volume pot with the Emotiva.

Would pairing it up with a LYR produce a more analog/tube sound? Would this still be overkill? Thanks for the help.

Also, seeing if I can get some guidance using reductive EQ. With more power through a dedicated desktop amp, wouldn't the HE-400 get too loud in the treble. I would prefer more bass so bringing down all the mids and treble a few DBs should even things out. Do the low end frequencies need more power as a general rule of thumb> Thanks for all the advise.

Schiit Lyr > He-400 is truly pleasant.  IMO, Magni > He-400 is rough in the trebles, in case of a SS amps, the Asgard > He-400 is softer in the trebles.

So I spoke with a few people in the Headfi community that was using the Emotiva a-100 with the HE-400.

 

I took the plunge. Luckily the Emotiva and Dragonfly are a perfect pair. The DF with its analog volume control makes it a perfect preamp. No noise floor, perfect sound. I have the Emotiva cranked up to 12 oclock. Plenty of bass .... now debating whether to get the HE-500 instead ... lol

Awesome. Is the 12 o'clock volume setting without using any EQ or digital volume control? I've been itching to get a SS amp for the HE-400 and the Emotiva is on my list. I'm concerned about how much of the volume knob is usable though. 

If you could share any general observations about how it sounds as a pairing, that would be very interesting too.

I have Application volume at 100% and am using the DF as a preamp. I set the Emotiva at 12 oclock and can play with the system volume/DF preamp from 10% - 100%. Seems to be a pretty good match. 

 

I'm also using reductive EQ in the -3DB realm in order to get more bass. 

 

I'm really liking the pair.

It's never a good idea to double-amplify ever. That's a recipe for distortion and clipping. 

That's just a myth. I've never experienced any distortion and clipping with double amping.

Using the Dragonfly with the Mini-X has given me the most bass I've heard out of the HE-500s so far. Definitely not the most neutral combination I've heard so far, but a lot of fun.

If both amps are strong with excellent signal to noise ratio and only on low amplitude, most people would never notice, and you're probably not doing much (if any) harm to the sound quality.


Take two weak amps with a high signal to noise ratio, turn up the volume and boom - you'll hear the difference.

Just out of curiosity. How do Pre-amps work? I thought I was using the DF as a pre-amp. I do not hear any distortion or clipping at all. I agree with Daerron, the bass is solid (HE-400). I have different EQ presets for bass. I am amazed :basshead: ...

 

My sub in my car seemed kind of weak this morning ... LOL
