Have you ever had the chance to try the standard blessing 2? I'm Interested to know if the Dusk version makes that much of a increase in bass. For the OP I'd recommend the Moondrop Starfield. You can find them new for around $110 or grab a used one on head-fi for 75ish. They have pretty good...

I have 2 IEMs from Moondrop, Starfield & Blessing 2, both secondhand. Never have had any problems from them even after some pretty hard falls except the paint on the Starfield started flaking off even with gentile use.
