I got my ZMF v2's today. They look great, especially with the leather pad, faux carbon stickers and very well done gold re-jack
I put the alpha pads on them from my 3.2 Mad Dogs and started listening to them with my e12 hooked up directly to my macbook pro.
Direct comparisons have been a little hard since it is not easy to swap the pads back and forth.
(disclaimer, I am by no means an audiophile, more of a music listening enthusiast, I have some FLAC music, but I mostly listen to 320kbps mp3's and Spotify on the highest quality streaming setting. I know that some of these impressions could be due to my humble set up and newness to the hobby.)
My initial impression of the ZMF's are that the treble is much more forward and at times sibilant relative to the MD's. I heard this on some vocal EDM and hip hop. To my ears, Im not sure I like the sound in this regard, relative to the MD's. However, they do sound great with organic instrumentation, especially acoustic and orchestrated music.
Even though these are the bass edition (v2) there doesn't seem to be as much sub bass / over all bass as the MD, although it is fast and punchy.
Hopefully Ill have some more to add later...
