I have a DT990 Pro, and the Fiio E11, the E17's equivalence of an amp. The E11 seriously struggles to keep DT990 distortion-free, and jacking up bass would be a death-flag.   I'm resorting to double-amping E11 -> O2 because...

I have been further enlightened...   1) Beyerdynamic DT880 600Ohm 2) Beyerdynamic DT990 Pro 250Ohm 3) Fake Audio Technica ATH-ESW9 (from here, the gap to the next ranking is really huge) 4) Audio Technica M50S LE 5)...

I think Maroon 5's Moves Like Jagger is a pretty good clean bass impact test: http://www.youtube.com/watch?v=suRsxpoAc5w   With my DT990, it hits harder than both of the songs you mentioned.

Here is an excellent pair of DT990 Pro 250 Ohm that I bought from another Head-Fi'er a while ago. Original thread here: http://www.head-fi.org/t/598284/beyerdynamic-dt990-pro-250-ohms-price-drop   There isn't any cosmetic...

Well, I did try to volume match the amps, but without proper measuring tools, the best I can do is with my ears, and I suspect it's off by more than 1dB in most cases.   But the problem is still that past level 6 on Fiio E11,...

It's funny you should say that, since I think the M50 actually has even more low bass and mid bass (especially mid bass) than my Beats Solo.
