Which is one great reason why I love my AMT headphones: estat-grade detail, and I can have the great bass response AND still hear minute detail

Just remember, when you change headphones, and your HRTF app has timing adjustments / head measurements (same thing), you need to adjust them again to get the sweetspot.

You neglected to link the pic of the chamber filled with polyfill :)

As am I but I have a Left shelf of +7.5dB, where you have a -1.5dB

ok, so you are using your own EQ, explains the bass response

I have planars, and the AMTs are digging even deeper, as they're rated to 10Hz. The performance in the subbass reminds me of a good sealed subwoofer. What EQ are you using? Do you have a good seal on your noggin? What amp are you using?

Bass roll off?

What country?

I have an SMSL M300 MKII, and it has all the features you would want from a DAC: solid AK4497 chip, has access to all the filter options of the chip, which helps getting that perfect sound out of your hardware, and has BT option if needed. Supports Balanced XLR and RCA SE outs. Has remote...

Instead of wearing headphones, you sit between two of these. Nice.

FR graphs are fine, with the understanding that it is a snapshot of a moment of how the sine wave sweep sounds individually, instead of multiple tones being generated simultaneously, over time. FR graphs do not show layering, or instrument smear, or other qualities.

And now for some semi-vintage love From 2007: Yamaha RX-V863 AVR and 6 x Infinity Primus 150 sats + C-250 Center. I checked the interior of the amp, and none of the caps show swelling or leakage. TY Japanese caps! No deterioration on the sats too, they were stored in the original...

take the pad off, and remove the hair with a tweezer. You can rotate the metal ring to remove the pad if desired. Rotate it in reverse to lock back into place. New foamies are cheap. You can also get the 2.0 version that the newer cans use with the stitched ring, to attenuate the 8KHz peak...

If you want some incredible percussions / snares, try out some AMTs.

I decided to pull out the Liquid Spark and hook it up to my tube buffer preamp, and compare it to my LP, and when I use the LS by itself, I pick up on the solid state character of the output, in comparison to the LP's smoothness. When I add the tube buffer, any harshness from the LS is gone...

This EQ came from a Redditor who owns the AMT, thought I'd share in case this helps inspire someone Preamp: -6 dB Filter 1: ON LSC Fc 105.0 Hz Gain 5 dB Q 0.70 Filter 2: ON PK Fc 22.4 Hz Gain 7 dB Q 1 Filter 3: ON PK Fc 70 Hz Gain -4 dB Q 1.85 Filter 4: ON PK Fc 80 Hz Gain -1 dB Q 1.3 Filter 5...

Yes, the padding and cups are leather, and I use leather cleaner on them. The M1570 are worth having if you get them on a good sale. I believe they are based on GP's GL-2000. They use the same balanced cable as the AMT. They have good performance, but they also have that typical Wall of...

I can understand this. In HEDD threads, I often see people preferring the fuller sound coming from the HEDD v1 compared to the v2, and the Monolith AMT is more akin to the v1 design, and subsequently the GL850. I've done my own comparisons to other kilobuck cans, and determined that the...

I too had to adjust the spatial timing in Redscape to account to the new cans, which once dialed in I was very happy with the psychoacoustics. Glad you are enjoying them as we do! I have the DT-1990 and M1070/M1570 and the AMTs easily outperform them for layering and imaging, let alone detail.

I did a minor update, putting the Low Shelf back to 105Hz

I hope the balanced cable you ordered works on the Monolith M1570 / AMT headphones, with the reversed pin layout of GoldPlanar. Just read your gear, and you are going from HE-5XX / DT-770 to the AMT??! Wow, you are in for a treat! Just remember they need EQ to correct mid flat response.

Agreed, I got the LS to be a portable amp and a backup should anything happen to my LP. This way I have a backup with a similar house sound signature. The Liquid Spark has been my #1 recommend to others looking at $100 amps for a long time, and I too snapped up one at the Ebay clearance sale.

which is your preference?

Picked up a Liquid Spark today, and just a FYI, it puts out more power than my Asgard 3, and I prefer the sound signature of the LS too.
