Here are a couple of more photos. I want to make quick mention of the fact I was very vocal about the comfort of the DK-3001. In my brief time with the DK-2001, to my ears, the majority of the prior comfort issues have been fixed, to my ears. I will have some time today for a long listen session.
The balanced tips are the color matching tips, and of the stock tips are the ones I have stuck with. The "clear" ones are transparency tips, and the red cored tips are vocal tips. I will do some tip rolling later today, try the Final Audio and Sedna tips, but the sound is nice with the stock balanced tips and I can achieve a seal, which is super important.
One more mention of comfort. The DK-2001 is a very thin profile IEM which really sits inside your ear. That said, I do not feel any of the annoyances that plagued me in the original. I can include a photo of how they sit, if interested.
Sound wise, thus far, the DK-2001 is just as stellar as the DK-3001, if not improved. Deep bass, overall very snappy signature. The treble is non-fatiguing or offensive in any way. Musical signature overall. I am hesitant to say more without a couple of long listening sessions. The sense of stereo separation is very good.
I left the thread hanging on initial comments, so I wanted post some more comments. More to come...
