Hi x838nwy, thanks for asking!
My D2000s got back from Panurgy yesterday. By the way, they did a great job repairing them, and even fixed the fraying on my old recable job. I didn't expect them to touch aftermarket work, so I'm very pleased. Cost $120 for a new headband assembly, $20 for labor, and $15 for shipping them back. Overall a fair price.
I use iTunes to play my files. I keep the equalizer off but damn, I certainly do enjoy that equalizer on certain settings.
Most of my files that I use for testing are ALAC, V0 MP3 (or better), and some FLAC->256kbps AAC converts that I do to save space.
Here's my setup:
2011 MBP 13" --> nuForce Impulse A to B USB cable --> Schiit Modi --> Schiit Psyt cables --> Schiit Magni --> D2000
2011 MBP 13" --> Grado 3/8" to 1/4" adapter --> D2000
The D2000s have noticeably better soundstage compared to my GR06 IEMs, where I did not hear any worthwhile benefit over the Macbook Pro's standard 3.5mm output. Maybe this is by virtue of having the drivers outside my ears for a change. In the past 24 hours I have felt compelled to sit back and enjoy my music on several occasions. Indeed, I am glad to have the Denon's working again. I have missed this feeling for 3 years. And that block-rocking bass... Still my favorite.
Comparing onboard audio to the Modi/Magni, the D2000 is getting
subtly better separation with the DAC+amp stack. I feel like the nuances of supporting instruments' timbres are more distinctly their own now, rather than meshing together into something like a background. To exercise tired rhetoric, I guess I am "hearing things I never noticed before", but I truly have to listen for it. I mean, listen for it in a way that I usually don't listen to my music. But I didn't know what I was missing until I heard it.
It dawned on me that I've been trying to listen more closely to electronic signals than the sounds of real life which they are often replicating. These real sounds surround us every day, yet I pass them without the slightest regard. Why should I value replications more? I don't enjoy the experience of live music enough to pay for it, but i'll happily pay $500+ to hear compromised reproductions. It's an awkward truth that some of you may have faced, but I'm recognizing it for the first time and I'm not comfortable with it.
This has lead me to a decision I didn't anticipate. I will be selling the D2000s. God I have missed them, but now I see there's no space for them on my desk or in my life. To me, they feel like a burden (emotionally, not at all physically! Could wear them for days). It's good that they're back in respectable shape again. I bought them here in 2009, and now I'm ready to pass them on to their next owner.
And it was a lot of fun experimenting. I've learned that I was happier before, so I should not continue trying to change things. But the Magni/Modi will stick around for now. It's so fun turning a nob for volume control.
