Yeah, I am enjoying them immensely, because I prefer that laid back sound signature. I do find them similar to the IE8's, but they also are a touch cooler than them. I'd say they fall about halfway between the IE8's and FX700's in terms of coolness/detail/smoothness. Sort of a mash up of the two. I'm still stunned that a $150 phone is superior to the $400+ IE8's (at orig. retail). It just shows how much the dynamic field is progressing, and how the IE8's are getting a bit long in the tooth compared to the competition.
I really like the mids on the DDM's. Guitars are very powerful, and strings are wonderful. I find it hard to describe the mids though, because they seem to occupy more of the overall sonic picture than any of my other phones, even the MD's. It's as if you have an X-Y linear axis, and the mids on the DDM's stretch a good deal wider for a bigger percentage of that space, than the other phones. But the upper and lower end detail is all there too. I've not heard anything like it yet.
