Hi guys! I just thought I'd give you a quick update after more quality time spent with the DDM's.
Basically, I've come to realise that these really are actually very polite and balanced, which is actually not what I was expecting given the gaudy design and huge bass driver (I know shigzeo's review stated they were balanced... but it was hard for me to overlook the design.) They have a dry, textured sound, with very controlled differences in volume. In terms of detail, nothing stands out but at the same time I hear quiet little things that I've never heard on other IEMs. Essentially, these don't seem to have the aggressive bite of my armature based CK90 Pros, making them less ideal for fast electronic music, but I don't consider this a negative thing. The bite can be a bit too much for me to handle at times.
Seal seems to be critical with these, but not in the normal way: perversely I find I enjoy the sound without a proper seal, as they open up and are more neutral. I gave my friend a listen, and he found them far too warm, though we both agree on other earphones, so we can only put it down to him achieving a seal with the Sony hybrid tips. (I deliberately chose a size that would be too small for me to get a seal, and he has smaller ears it seems.)
Shigzeo is right - what these do best is acoustic guitar and piano. And I mean, best, as in when the right track comes up on shuffle I just mentally pause and soak it in. For some reason, the timbre and sound of these is perfect for piano - they sound like real instruments, and its quite breathtaking. They are especially good for quiet tracks, though by no means do these lose cohesion at louder volumes.
In case anyone is wondering, YES these sound even better when they are amped. Plugging them into my little uDac, everything just seems more cohesive. I've been using them to play games, which is pretty fun in itself.
For my fellow DDM owners, here are some tracks that I heard that just sound amazing, plus some higher quality youtube links for a preview. (Thanks to the handy &fmt=18 hack :D ) These are also some of my favourite tracks, which gives you an idea of how random my shuffle can sound.
Another Saturday - Stuart Murdoch, from the compilation album Dark Was the Night

Really sweet acoustic guitar track, with great mastering. I don't know guitar terminology, but the texture of the strumming... wow. The male vocals layer so nicely as well.
Joy Luck Club - Massive Attack, from the album Collected
http://www.youtube.com/watch?v=z_JTD2sPFV8&fmt=18
The youtube link for this sounds pretty cruddy actually, but I use this track for testing speakers. The DDM's soak up the bass on this, but the ghostly female vocals just float (all creepy like) thanks to the wide soundstage.
Truce - The Dresden Dolls, from the album The Dresden Dolls
http://www.youtube.com/watch?v=M6y9mjwAR8o <-- Horrible anime music video link...
My apologies for the youtube link, for some reason the &fmt=18 doesn't seem to work for this one, and the only version I could find was a horrible AMV. Just try to ignore the visuals. Amanda Palmer, is one of my favourite artists. She makes an almost psycopathic genre of caberet music with a macabre sense of humour. She's a brilliant lyricist, this is one of her slower songs. When she whispers on this track, it feels like a whisper in your head. The cello in the background is a highlight. Everything she does sounds good on the DDM's actually.
Give these a go :D
Edit: For some bizarre reason this is all in Times New Roman. I have no idea how I even did it.
