Mine arrived today also. Just to state my tastes, I use the CK10 and Ortofon eQ7 and like both very much. I also have an SM 3 and still sometimes like to listen to my Shure E 500. I still have my ETY 4 P's and occasionally use them. With all the discussion of sibilance and other problems people have been talking about, I was getting very curious about what these would do. Right out of the box with the stock tips they were packed with, they sounded excellent. My very first impression was, "these sound like my CK 10s but with a much larger sound stage." I was listening to them out of an Ipod 7th gen played through a Mini Box E + portable amp. I thought the width of the soundstage really quite good. The detail, was on par with the CK 10s, but I thought both the male and female vocals were better. The vocals sounded very natural to me, no artificial huskiness to the male vocals, nor did I hear any exaggerated aspects to the female vocals. I thought the instrument placement very good, the highs were very clear without sounding exaggerated, and I also thought there was decent depth to the presentation. I did not hear any sibilance or grain to the sound. The bass sounded a lot like the CK 10 and the Ortofon eQ7 and I didn't find it lacking. With my setup, there was also adequate warmth to the sound, so I didn't find them clinical or cold or aggressive. Now, my ETY 4s I find all of those things, they are much colder and harder sounding than the DBA's and much more aggressive in the highs and not as smooth. The DBAs sound very natural to me, but at the same time very clear and "present." Another impression I had right away was that they sounded a lot like I expected the SM 3's to sound from reading other people's descriptions of them (with the exception of the bass), but I could never get the SM 3s to sound that good. I had the same impressions of the sound after burning them in all day.
From all the variance in impressions, I think it, among other things, represents the variances we all have in ear structure, and how various tips seal for us. I get a good seal with the with various DBA tips, but getting the SM 3s to get a good seal for me is very difficult, and the sound of those varies greatly for me with various tips, so I wouldn't be surprised if some folks have the same kind of issues with the DBAs. Fortunately, I don't, and I am getting an excellent, large, clear, slightly warm, highly detailed, and very engaging sound from these IEMs. Good luck to everyone with theirs.
