As you can see, the headband paper was never taken off, and it
It also comes with expensive lambskin alpha pads.

As you read in title, it is also a "DMT" moded Headphone, which goes way beyond traditional methods of simple materials tunning.

DMT is "Driver Modification Technology".

It is a totally new, and, alternate approach to modifications, requiring a specifically calculated and tailored re-design approach into each type of driver, boosting it's performance.

The driver modification process basically diverts the energy more narrowly into the voicecoil area.
This increases both sensitivity and resolve.

This unit is a successful "proof of concept" design, to elevate the THX00 performance above all other tHX00, and compete easily with the fostex th900 in resolve.
As such, It is the only unit made, only to prove it can be done.
There will be no modification business, as this only my hobby.

Yes, this is the same infamous THX00 PurpleHeart that I challenged in past, to beat a th900.
I nicknamed it the "Purple Heart Revenge" .

I will post before and after CSD results:
Stock:

DMT moded:

Notice clean area of no decay above 1khz.
All competitors have excessive decay up to 2khz.


Here is the Frequency Response:

Yellow=stock
Orange= DMT moded.
Notice the rediculously linear trebles area.
This means transparent signature.

Also take note, the rediculously linear bass response that does not waver or go down, even to 10hz and below!

The dip at 3k is according to the "Harman curve" ear sensitivity, which results in the most balanced signature.

Soundstage and detailing is increased as well:

This is a prototype, one of a kind unit, and the best performing THX00 available.
PM me for any questions.
Here is a link to some TH900 measurements posted here, for comparison.

Asking best offer.
Both US shipping and Paypal included.
