It's funny - I've been going through all my IEMs again lately just to see how I feel now that the initial excitement has died down. After comparing the DDM to the RE0, the CK90 Pro and the RE252, I still really like the DDM - its amazing for acoustic instruments and male vocals, and nothing else I own comes close when it comes to conveying emotion and timbre. They still convey microphone placement and other little audio cues with eerie presence.
I just wish they were a lot faster. I listen to a lot amount of electronic music, or at least music music which uses a lot of synthesized instruments, and sometimes I miss that crisp bite that the RE0 et al have. That would be my main complaint now comparing it to my other IEMs. I have bizarre fantasies where you could have the bass driver of the DDM and a balanced armature treble driver together (sick I know), and the only other IEM I can think of that does that is the somewhat maligned SuperFi 5 Pro EB.
I'm also wondering what portable source would go nicely with the DDM. I find it a pretty poor match with the iPhone 3G, and a pretty nice one with my trusty Sony S739. I'm at a point where I will probably get the iPhone 4 when it is released in Australia (hopefully with an antenna fix) and I wonder how that will pair.
Listening to frequency sweeps on both my 3G, the S739 and the headphone out of the uDac, its actually pretty obvious where the sound crosses over to the treble driver. It suddenly dips softer, and the treble driver is actually a little mushy in its sound. It's most obvious on the 3G which seems underpowered, and very subtle on the uDAC, so I think this IEM exhibits the same hard to drive characteristics as multi-armature IEMs on portable sources. I'm curious as to what everyone's opinion is on this?
All this of course makes me very excited about the next DDM radius plans on releasing, which I would snap up in an instant if it improved the treble.
