Which Tweeter preferred- dome natural material, Beryllium/Metal or Planar Ribbon? Why?

The ESS AMT will shine when played using a high current solid state amp, but they don't do nearly as well on tubes.

In these videos, I went to extremes to match the volumes and the Vanessa track is within 0.1 dB while the SRV track is within 0.5 dB, both in favor of the Melton.  Everything else is held constant.

Which is why you need to INSTANTANEOUSLY A/B them with everything else being IDENTICAL as I allowed for.  Did you watch the videos?

Maybe a different tube amp would have a different outcome, but others on another forum also find this to be true.

I modified my AMTs to take the peak out of the high end (~10kHz) using a diffraction lens I designed/developed, and to boost the lower end by extending the flair.

I also remove the back wave because I don’t want the reflections, which can be unpredictible.

I also designed and made the stands out of 3/8" smoked acrylic cut on the laser table.  I also have a pair in clear if anyone is interested in them.
