Song Tested With:
DJ Shadow - 'Dat's My Part'
Mr. Scruff - 'Shrimp'
Hot Chip - 'Keep Fallin''
DJ Shadow - 'Walkie Talkie'
Unamped
Now this was pretty interesting. I first listened to the tracks with the M-100's, then switched to the MK2's and WOW are the MK2's more sensitive. Had to click my volume down a few notches.
This was the first instance in which I compared the M-100 with another headphone I own, so I wasn't sure what to expect, but the difference is huge. The MK2 is, first off, waaaaaaay more cramped that the M-100 (although this should go without saying, it was a night/day difference). Strangely enough, the M-100's highs also roll off BEFORE the MK2's. This is a GOOD thing. On the MK2's, the snare drum in a few pieces were piercing and...not the most pleasant. The M-100's highs are sparkly but not piercing. Very easy to listen to, while being clear and not dangerous to your hearing!
Next point, mids; Both cans share a U shape frequency curve. I'd say the MK2's mids were just a tad more recessed than the M-100's. Due to the wider soundstage of the M-100's, however, mids sound much nicer on them (as much as people say it's likely their weakest point).
Next, bass/lows; Um. Are my ears broken? No. Check. Double-check. The M-100 beats the MK2 in bass reproduction; both quantity and quality. No joke. Completely serious. I don't really even know what else to say.
WINNER: M-100 (by a few miles)
Amped w/ DigiZoid ZO2.3
Truth be told, no major differences from what I posted above.
One difference I would make note on is the fact that the MK2's actually lose a bit of detail across the spectrum when amped, and I actually see a larger improvement in the M-100's amped vs. unamped. This may be due to the fact that the MK2's are insanely easy to drive.
Concensus:
Do yourself a huge favor and use Miceblue's paper towel mod, buy a ZO2, and enjoy one of the best portable setups I have ever heard, ever.
P.S. - DigiZoid ZO2 was on High Gain mode, and at Yellow-Green contour (more yellow than green) for all testing.
