I don’t imagine you’ll find a source that f**ks with the DK3001 too much. Well-balanced tuning usually makes a monitor highly compatible with a wide variety of devices. Still, with all that treble, however smooth it may be, you could see some trouble if the source has too much upper-range energy. So be aware of that.
theBit’s Opus#2 is ever so slightly warm, with god-tier resolving power, and superb dynamics. Highs and lows are meaty and attack strong. Mids are the most natural and realistic I’ve ever heard. The DK3001 finds its soulmate here, in a DAP which exemplifies its own best virtues, and pushes it as far as it can go in those areas it struggles with, like detail-retrieval.
The Opus#1 is my favorite mid-tier DAP. It’s not as warm as #2, nor as full, but there’s more energy. Like a younger brother. Its treble, especially, owns some extra bite. But it’s not enough to turn the DK3001 from its awesomesauce ways. In fact, the Opus’ dynamic-neutral presentation gives DUNU a favorable tilt towards resolution.
Cayin i5 is not as solid a pairing for DK3001. Because this DAP renders very warm and smooth, it does nothing to aid in this IEM’s struggle with details and resolution. What Cayin does best is brute-force musicality, with super power in the bass department. The DK3001 really comes alive. It’s not the clearest or most accurate sound, but it’s a lot of fun.
If you’re on some dastardly-low budget and still want an i5-like powerhouse sound, Shanling’s M2s will gladly fulfill your needs. You lose a little refinement. A little depth. But tuning is spot on. The M2s is a tiny little player which excels at big and warm.
Well there it is. The DUNU DK3001. My ears may hate having them in, but they love what is heard when they are. Is this the masochist’s IEM? Or maybe a devious stratagem to train the populous to become masochists? But to what end? Is there a new wave of Punishment Porn on the horizon? How will this impact the economy?
I’ll need to ponder this further, and reexamine my own private appetites… see if I can’t stretch my personal boundaries.
