imaging and soundstage is important to you I would buy the ATH R70X over these any day.
This may have sown the seeds of doubt in my mind, Soundstage is really important to me since i game a lot and having a good soundstage really enhances the experience for me. I'll be sure to take a look at the ATH R70x, since it's way cheaper than the DT1990 Pro here in Brasil, especially after tax (about 250USD of difference)
I don't think that'll be a problem for me, my ears are definitely on the small/flat side. I'll await for the MM100s from Audeze first before deciding, but looking at the price and some graphs, I think the R70x will probably be a better fit for me compared to the DT 1990 PRO, as of now, I don't think I can justify getting the Beyers since they're double the price of the R70x for a, what I assume after looking at some reviews and such, not double the price worth difference.
I just wanted to thank you for recommending the ATH R70x, if the MM100s aren't accessible here on Brasil, I'll definitely be going for the R70x :D
