HE-6 modding/amping thread
« on: February 05, 2015, 01:58:58 AM »

Since I have not found a thread devoted to mods for the HE-6 I thought I would start one.

I originally bought the HE-560 and HE-6, then sold them when I figured the HD800 would hold me over until the HE-1000 came out.  Then I heard and purchased Bill-p's excellent modded HE-560, and since then (only a little over a week ago) have listened to the almost exclusively.  Then I got an itch for the HE-6 again and bought a demoed/open box version and did the basic mods right away: regrilled, took out the white cotton from the back, and fuzzorred the inside sides of the magnet array, but used 1mm thick felt as I could not find the 2mm felt.

IN fact I actually sandwiched two sheets of the 1mm together and cut them and put them in, but they were not amenable to being rounded on the edges a la Jerg's suggestion.  So I just ripped them out and used 1 sheet of the 1mm, at this thickness there's not really a need to round the edges.

That's it, I haven't done anything else yet.  I'm running them out of a Rag, it's much better than any of the other head amps I have, but haven't tried them with a speaker amp.  Also I want to change the headband to the HE-560/400i headband and am working on getting one.  Anyone try that yet?

Sound improvement?  I have tin ears, I don't know.

Don't put a HE-560 headband if you plan on using the Audeze Vegan pads later on: they are incompatible.
The HE-560 sound so great with the Vegan pads that I'm actually considering swapping the headband for the old type  :-DD (which I was never annoyed by).

I am content with the no-grill mod for now. I am not good at removing and reattaching the pads hence I've held off on the fuzzors. However, I don't have an issue with the treble. Pairing this with the Stratos Extreme power amp has provided more of a neutral sound. I had previously used my JVC receiver and it was definitely more on the dark side.

What do you mean the Audeze Vegan pads aren't compatible with the HE-560 headband?

I was under the impression that the two headband types themselves are incompatible. I sent an email some time ago during pre-production phase and the rep said that you couldn't use the HE-560 style headband with the older models.

Which is a shame, since the comfort is infinitely better with the newer style.

I'm not talking about mounting here. Just the way the headband, and especially the yokes, work with the cups:
- On the older headband, the yokes are rotating on the outside of the cups; No matter how far you stretched the headband (pull the earcups apart), the yokes would never cross the inner edge of the cup, where the pads are.
- The new headband works by pulling the cups from the inside. Unless you have a narrow head (like me), when you stretch the headband to normal head size, the yokes cross the inner edge of the cup and, thus, hit against the Vegan pads (which are bigger than the cups). This put pressure on the temples :/

I hope I can find a way to fit the old headband to the HE-560...

True, it's because the ear pads are too big.

I have not been able to remove the HE-6 cups from their headband as I used a screw driver too big and it stripped the cross pattern!  So its out for me on the HE-6. 

Have you taken off the headband assembly for the HE-6/500, if so what does the hole in the cups look like?  All I see is a plastic washer between the cups and the steel gimbal.  It's probably easier to put the 560 cups on that steel gimbal than the other way around.  the HE-6 cups would need to have the holes (expanded by drilling?) fitted with the same nylon bushing as the 560 cups.

I actually had the same problem with my HE-4: the screw got destroyed when attempting to unscrew them...
We shall see if I'm more successful.

Honestly, after de-stressing the headband, the HE-560 + Vegan pads work for me. I can still feel a bit of pressure on the temple but it is not unbearable.
The sound is just gorgeous, though... I was never a big fan of the Vegan on HE-6, but with the 560s it is definitely great.

Armaegis, good luck with the headband, I think you can try this one on taobao:

http://item.taobao.com/item.htm?spm=a230r.1.14.118.98Cjmx&id=36402141950&ns=1&abbucket=17#detail

Taobao is a Chinese domestic site like ebay/amazon marketplace (actually it's much better in terms of variety and cheapness), but as far as I know you need to have a Chinese bankcard or alipay account (which requires a Chinese bankcard) to use, it's basically a nono for non-Chinese residents.  Apparently there are resellers (I've never used one) who offer the service of buying listings and sending them overseas for a fee.

credit goes to azncookiecutter  headbang for this:

For buying stuff from Taobao using a reseller: http://www.vendio.com/stores/E-sports-Gaming-equipments/

I don't know cost of cheap shipping from China to Canada. I have done lots of shipments but use regular couriers like DHL/UPS, etc, those are expensive, minimum $30 for a document $40 for lightest package, most of these Chinese vendors use postal and for whatever reason have really cheap rates, you would always want to go with that or else shipping will kill you.  It's something I'll have to research next year.

Armaegis, some things to consider:

1)  You should still contact hifiman and wait for their response, I am also in contact with their customer service and it is...  a bit slow.  But it's $50 for the HE-560 band, I would guess it's similar for your band.  You mentioned your screw heads are stripped, in that case you would need to use a hifiman band as they would just connect your existing gimbal part to a new L-shaped length adjuster (if you look the gimbal is connected with a flathead screw, so you don't need to disconnect your cup from your gimbal).

2)  If you get the Chinese aftermarket headband, just looking at the pictures there is no guarantee that the hole on the gimbal is compatible with the screws on your HE-6 cups.  If you look at the posts they use in the pics, there are not threaded, it looks like the HE-560/400i style where they slide into a hole.  IN which case it is wholely incompatible with the HE-6 unless you are willing to majorly mod your cups and drill holes where the sunken threaded hole is now.

The one good thing about the Chinese aftermarket headband is that the L-shaped metal length adjuster looks about 10-20% thicker than the Hifiman metal, it should not snap.  In fact yours should not have snapped at all, yours must have been defective since the beginning, I'm looking at mine and no amount of regular stress would have caused any sort of fracture in that bend.

Actually, I'm pretty certain that Taobao takes payments from credit cards outside of China too, but it goes through an intermediary that appears to be their version of Paypal. I bought something off Taobao directly that way a few months ago.

Thanks. I'll have to look into that reseller...

Frak, it's like they've put loktite on everything. That screw isn't budging even with two vice grips.

Do you think there may be an acoustic leak from the jack hole? ~Tyll Hertsens

Not sure if I like stuffing one hole or both holes. Tending toward one hole since both holes seems kinda ghey ~Purrin
