From the master thread on HF:


HD800 no mods

 
HD800 felt mods
Two layers of felt around the ring. One layer of felt on the plastic.

 
HD800 Arnaud mods
Two layers felt around ring. One 2mm foam layer on plastic. Download all three HD800 plots into a picture viewer to see the minute differences among them.

 
This is with foam instead of felt on the driver ring.

Anax mod v.2.1 is finished.  I believe we've finally nailed it.  More to come later.  Tired.  Bye.

I've been pairing an Anax modded HD 800 with a Luxman P-1u for a bit and have really enjoyed the way it sounds.

Haven't had a chance to hear these myself but the HD800 are known to be very good for imaging and soundstage.

From what I understand, sound localisation is something to do with high-frequency sounds and it is quite clear that the HD800 has very amazingly fast and clean CSDs basically 1KHz and up.

Does anyone know which frequency range in particular is important for sound localisation in headphones? (if it can even be determined in this way...) Could it be due to the plateau in the frequency response graph from ~5-15KHz? Could it largely be due to the lightning speed in the CSDs from 10KHz and higher?

I'm basically wondering if it might be possible to identify other (less expensive) headphones that might be able to be classified as having a good soundstage and imaging because of any properties they might share with the HD800 in this regard.

For a start, perhaps the AKG K701 could be close? CSDs linked here on Changstar's front page look pretty good to me.

Though it really does not fare as well in the THD+noise measurements available on InnerFidelity compared to the HD800.

The LCD-2 R2 measurements here show that their CSDs are very clean, but the impression that I get from what I have read is that they do not image particularly well? If it is true, could it be because the higher treble is relatively shelved down?

Not-so-hot shape one (needed pads replacement badly at least)

The answer is ReferenceSounds (LFF et al.) Code-X. I would describe it as a mix between LCD-2 and HD800.

Speaking of pad replacements, where the heck can I order some? Senn is completely out in the US.

If you don't mind the smell, I believe mrscotchguy over at HF has a spare set...

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

HeadRoom has them in the USA and they are expensive. The replacements came in much thicker than my original pads also. Very interesting!
