Shure makes some killer stuff and should be properly respected as one of the OG's of the IEM game. Shure E500, a triple driver model, 10 years ago? Thanks for that! However, as interesting as the KSE1500 seems, I'm absolutely NOT sold on the little black box it comes with. Specifically the DAC portion. If I'm running an expensive IEM I want to use a top caliber DAC to feed it. Not some outsourced little mystery box. That, along with price, seem like issues for me.
