This is an intriguing produce...a bit on the high priced side, but if it can do all it is supposed to do well, could be worth it (getting separate player/portable amp/dac takes up space and costs much). I haven't been able to get the sense from quick browsing if it is able to drive most cans...have many different well known iem's (Westone, Sony, Ety's, more), also recently got Senn 650's. These are the one's I'm wondering if this player would drive well without me missing an amp. I have various Apple players, the HiSound Anniversary 3 Studio (which does drive the Senn's adequately, but I'm always battling the software/UI, not user friendly in my hands), also doesn't handle high-rez, which I have some (though most of my digital music is in Apple of various flavors and regular FLAC). Any thoughts out there? Searching the amp reviews/sales, would this be a good alternative?
