Hahaha: https://mrspeakers.com/shop/3-accessories/ether-and-ether-c-1-1-upgrade-foam/ I had an Ether on loan recently from an anonymous donor and found that you could really improve the sound by adding a bit of front damping foam (with hole cutout in middle so as to not make sound too dead). The stock black foam, on top and bottom side of driver, could be replaced on the Alpha Dog to improve the sound, but I didn't try replacing it on the Ether. I see some other areas of opportunity to reduce reflections off hard plastic. In other words, plenty of opportunity to make these sound really darn good tonally via front damping mods. The stock pads make the soundstage sound like garbage. Very close to the left/right with a 3-blob effect otherwise. I did not try other pads when I had the Ether. My concern is finding thicker, angled pads to improve this without throwing off the frequency response too much. Plenty of potential here, to the point you might be able to make it competitive with or better than similar planars in this price bracket. Or you could save the money, get an HD650, and a nice tube amp and get better sound.
