If you get the ATCs make sure you have more than enough distance to allow the drivers to blend.
when I heard them the dome midranges were noticeably incoherent with the other drivers (they have a very limited bandwidth compared to a conventional midrange). This resulted in frequent image shifting in vocals- very unpleasant.
I was listening from about 15 feet away, i would recommend at least 20 feet.
the Spendors on the other hand are incredibly coherent from 9 feet and beyond.
