That was what I was going to suggest, it's sort of deflating to own multiple pairs of phones that sound similar to one another. Although that sort of thing would definitely be handy if you enjoy the sound of a full sized pair of phones but want a similar sound signature for on the go. I myself am partial to a warmer, more musical sound than a colder, analytical one. I just find the music more pleasing, exciting and engaging when listening to the former than the latter. As such, my favorite phones are the Radius DDMs and the RE262s, and the SM3 is supposed to be the ultimate universal phone carrying that signature.
The Fischer DBA2 is more on the neutral and analytical side, and would be excellent for electronic music due to their speed and resolution, but I'd say the DDMs would satisfy as well due to the width and depth of their soundstage coupled with their amazingly textured bass reproduction (it hits very low, and very hard when needed). It'd be hard to beat out the DBA2 since they aren't lacking in any category, but their balanced armature design means that they lack the punch and weight of the DDMs mid and sub bass so they aren't as "fun", it just boils down to what you prefer I guess. I'd make sure to research thoroughly and not only read about the SQ of the phone, but also its isolation, fit, and portability qualities as well. (e.g. The RE262 becomes a whole different beast when amped, the DDM is not the best portable phone etc.)
