That's why the 1990 is so tempting....need to resist damnit!
Yeah, if you do get it, wait for the special deals that pop up on it. They are somewhat similar too, you can tell they are in the same family. I ended up getting the DT 1990 for $400 as they never sent me the amp so they refunded me $130. I got the Amiron for $479 and sold the FiiO E10k it came with.
