I see you have the same Meier dac/amp setup as I do. I loved my DT 770 Pro, but sold it to a friend when I wanted to try the Fidelio X2 (ended up being too dark for me). I was tempted to get the 1770 Pro, but I felt it might be too similar to my Fostex X00. I was looking to upgrade to a flagship open headphone, but was having a tough time motivating myself to spend more than a grand. I write reviews and like to have a couple different headphones (along with my room speaker setup) to compare, but man, is an Ether Flow really worth the extra $1,200?
Beyond the other Beyer phones, what would be the closest comparison/competition for the 1990 Pro?
