I've been hearing a lot of good stuff about that amp. Like how do you connect the headphone to this speaker amp?
 
Do you have any reference amps which you can compare it too? For example something like the E9?
How does it improve the sound?
 
Lot's of questions, I'm very interested in this amp :)

 
im using banana plugs to female trs jack.  cheapest and most versatile way to connect HPs to the amp

the emotiva takes the he400 to their full potential IMO.

I have completed the first version of the marleypads :D
 
First sound impression: They sound like the velours but more balanced. They still sound as dynamic, so bass is much more punchy than with the jergpads. But mostly imaging and soundstage is back, it is amazing.
 
The jergpads do sound more romantic though, however I like a more dynamic sound.
I'll open up a new thread where I'll write up a how-to marleypads in case anyone is interested in replicating this experiment.
 
p.s. When I say jergpads, I mean my implementation of the jergpads. Maybe I did something wrong? But I think most of the problems of the jergpads (smaller soundstage, slightly slower sound) are inherent problems of the pleather pads. They are less deep and softer.
Also major props to my girlfriend since she did all the stitching and pattern designing!

What is a more "romantic sound"? And what do you consider to be "dynamic sound"?

Probably the amount of midrange bloom / emphasis. Pleathers / modded pleathers will always put the ears really close to the drivers, thus emphasizing the midrange, and pushing back the treble and bass quantity.

Yeah sort of, things sound is a bit slower and warmer on the jergpads. It's a little bit like the HD650.
 
With dynamic I mean more punch to the sound, specifically more punch in the bass.
 
The main differences between the jergpads and marleypads are the following: the marleypads seem to have better imaging, a bigger soundstage, tighter and punchier bass but the mids and treble are pretty much identical. I definitely like the marleypads better (biased much?) however some might like the jergpads more. It's much closer to the sound of the HD650.
 
The jergpads are still undefeated in terms of comfort. I did soak the velours in soapy water, which did make them a bit softer.
But I think that the hardness of the pads actually contributes to the dynamic sound of the velours.

Ugh!  It looks like Comcast is cutting out the use of personal Web pages.  My "taps.PDF" is no longer loading.  But, here is the guide on the necessary cable to connect to a speaker amp:

The inspiration for these pads came from the jergpads. The balanced sound was amazing but I thought these pads could be even better with deeper pads. Having my ears so close to the driver resulted in a more intimate soundstage, and imaging of instruments wasn't as impressive.
 
So I took the velour pads and stitched leather over them :D
I also added some damping holes to reduce reverb, which wasn't really apparent but I thought it couldn't hurt.

Soapy water? Now i am confused..somewhere else a person states to wet the pads with just water..and then push the water out a couple of times and let it dry..but now u say soapy water? Guys..whats better???

I actually thought the guy said to use soapy water before he said just water :p
 
The question is: How dirty is earpad? I don't think it matters much for the softness of the pad though.

So you need to convert to xlr first and then to taps? You can't make a straight cable from trs to taps?

You can't use a TRS (3 conductor) and mate it to the 4-pin XLR.  A speaker amp or receiver, can't (in most cases) operate with both ground (negative) signals connected together.  There are very few that will allow the ground to operate in such a manner.  Very few.  In fact, I'm not even sure on which ones to name, since I've only heard of a few pieces in passing.  Yet, 99% of all the other gear requires the use of 4 separate conductors (2 Positive, 2 Negative.)

You can with the emotiva.  the emotiva has separate grounds.

So how was the Asgard 1 with the HE-400 overall? Did it drive them well? Anybody have any insight to whether it might be a good idea to find an Asgard one for cheap second hand once the price goes down, as it should, as a secondary rig/bedroom rig/etc? Any insights to whether it drives the Mad Dogs and LCD 2 as well?
