@trellus I see that you own a Stax headphone. How do they compare to the Monoprice AMT's?
That's an excellent question. :) I've actually never directly compared my L300 and the Monoprice AMT's, come to think of it -- but just from memory, the tonality is way different, for sure -- the L300 sound more neutral to me than the Monolith AMT's, the AMT's are definitely more colored and the L300's frequency response helps reveal the detail better to my ears than the AMT's, which seem to sometimes get obscured in the warmth.

That's purely from memory, but the L300's are more comparable to other closer-to-neutral headphones like the HiFIMAN Arya Stealth and the HD 600, or even the Heddphone, whereas putting on the AMT's, they are very amazing sounding but "off" in some way in the FR that sounds unnatural... but pleasantly so.

I have not tried EQing the AMT's because I generally never EQ a headphone, but I will admit that while I don't want to EQ my Stax L300, every time I put on the AMT's, for a second at least, I think it needs EQ... but my brain adjusts to the FR, and then I forget it's noticeably colored until I put on more neutrally toned headphones.

I agree. The AMT is kind of addictive in its sound but also has characteristics that make them less neutral and more "fun" sounding. On some tracks, the tonality is pretty good and others, there seems to be sudden changes in its tonality that are noticeable. It may just be the recording but I do think that the tweaks/mods and EQ make these AMTs more enjoyable IMO. They do lean on the darker side and in terms of speed and resolution, I think they are really good for their on sale price. I also think that EQing these AMTs are more of a challenge then say an Audeze LCD.

You mentioned the Heddphone. I've never heard them, but i assume the presentation should be similar to the Monoprice's AMT?
