AMTs were taken off Ebay, and mp.com has them at full price, so meh.

I do not know what's the strategy - if there is any - behind these price variations, and of course I cannot say that I appreciate them, having purchased the AMT at full price, but...I am putting these beast cans under scrutiny again during the last days and, despite the grand I spent, I can't really complain. No EQ, no polyfill mod, just burn-in: the AMTs keep improving and shaping an addictive sound.

You can be like @hottyson and get 1-2 pairs for "just in case" when they go on sale again down to $450.

I have multiples of Monoprice M1570. Crazy cheap sales in the past, but I might have to pick up another pair of Monoprice AMT someday if the sale price goes crazy low again.
.
Multiples of Koss KSC75 and PortaPro and SportaPro. Portable bargain$.
Two pairs of HiFiMan HE6se V2. But, one needs to consider an expensive known to pair well with amp as part of the equation.
Two pairs of Sennheiser HD-600. The most important staple headphone of any collection. Especially if one has tube amps or multiple good amps.
More people should consider purchasing more than one of HiFiMan HE6se V2 and Sennheiser HD-600. They are THAT GOOD for the $ when they are on sale.

I would like to introduce you to my nearly 30-yr old set of HD-580. Sporting indestructible Dekoni Elite Velour pads, and replaced headband cushion, and a balanced cable:

(Yes, I got tired of paying the Sennheiser tax and buying new pads every 2-3 years at $50 a pop for OEM replacements because the polyfill in them collapses on itself)

After some time with this headphone, It is beginning to become one of my favorites. One thing I've noticed is that it scales up quiet nicely with better gear and source chains.

 

[giuca70]

has anyone else tried this mod before? if so what were your results?

my AMT was the subject of a 3rd acoustic revision, which had the aim of arriving at a middle ground between the stock version (excessive rumbles) and the version with acrylic filaments to fill the internal indirect resonance chamber (no rumbles) .

Simple UHU Patafix (removable like acrylate wire) to deafen the internal and indirect reverberation chamber. Sound balance is good, headstage, space.

Curious to hear who here considers their AMT's to be their endgame?

I do. I've had numerous different SOA TOTL headphones, mostly planar magnetic, and the superb voice coil driver Sennheiser HD800S as modified by Stefan Audio Arts, but the AMT always beats them for immersivity into the sound field, resolution, transparency and bass quality. I've not tried some of the very most expensive alternatives especially ones like the Susvara that require a very high power headphone amp.

Perhaps it represents one of the headphones with a compelling stage representation, similar to reality, with a large space between the instruments, a bit like listening to an orchestra or an event live.
One of the planars that I also define as true is the Hifiman HE6seV2, omnivorous enough, with the right setup it is perhaps superior in definition, but we are talking about obvious differences.
My 3rd modification on the AMT is the compendium of the first 2.
The first time I filled the back of the driver with acrylic filament, stopping any reverberation, the bass dried up.
in the second modification I balanced the cable with a total of 192 copper cores, and here the need arose to make it less of a monitor.
So the 3rd modification was to remove the acrylic and insert UHT Patafix, an adherent, malleable, light rubber, which reinforces the external pavilion by deafening it, limiting the vibrations of the basket, and at the same time dampening excess reverberations.
The result is an extended three-dimensional aria, rich in even harmonics, without those reverberations and vibrations that made the bass ugly, now more ethereal and real than ever before.

tried the uht patafix mod and its exactly as you described. thank you!
