I am just back from the Munich high end show. I went there mostly for TOTL headphones and high end headphone amplification. I will give you a synopsis of my impressions in a few days, today though I want to share my findings of a new headphone I discovered there, which is driven by a so-called ATM or Air Motion Transformer. http://www.hedd.audio/en/announcing-heddphone-a-new-chapter-in-headphone-history/ According to the developer the price will be well below €2000. The sound quality of this hand-built prototype was already so impressive that, IMHO, this headphone could compete easily with other, well known TOTL headphones. I was so impressed by it, that a planned upgrade (initially I had planned to upgrade to the new Abyss 1266 TC) will have to wait until autumn, when the official release of the headphone will be. Air Motion Transformers are ultra fast, high resolution drivers and you could clearly hear this. Some people might say that ATM drivers are lacking in base quality, I did not notice any weakness in base sound quality. Like I said, any planned headphone purchase will be delayed until the release of this hp, because an audiophile dream for well below €2000 could be in the making with this headphone.
