Could be this has been asked before, but how does these stack up to Focal Sphear and V-Moda Forza in terms of bass, comfort, isolation, and sensitivity (will be using them without preamp)?

OK, and if I was to go the amp route -- what would be the best value ($50-80) amp for non-portable use?

Is there any DAC/audio interface that does?

Would EMU 0404 USB with its 22ohm output impedance and maximum output power of 20mW be able to drive Beyerdynamic DT880 250ohm?

Would something like FOCUSRITE VRM BOX suffice?   http://uk.focusrite.com/usb-audio-interfaces/vrm-box/specifications

I'll be traveling for the next few months so I am trying to figure out the new production setup. I've been using Focal CMS50 monitors and EMU 0404 USB audio interface in my bedroom studio with no serious headphones but since I can't take monitors with me, I've bought Beyerdynamic DT 880 250ohm...

I, for one, can't stand cans anymore. Been headphoneless for few years (having rather good speakers though) and nowadays my AKG K81DJ and wife's SENNHEISER HD-25 both sound awful to me (well, I can adapt my listening pleasures to them if necessary but that's it) -- the KSC75 seems to be only...

indeed! I've got mine a while ago as well, completely due to the ravings in this forum, and despite the obviously well deserved hype, the actual quality of sound still brought surprise! // although they lose some magic if not directly pressed against ears.. is there a mod against it?
