Hype? I think they're under-hyped. I just got into 'Chi-fi' at the beginning of the year. Yes I know, I'm late. I got my first IEM and couldn't believe the sound quality and workmanship for $25. Then I got curious at what a $60 or $70 IEM could get me. Well, I was even more surprised than the first time. Then I got two SMSL DACs and a Topping headphone amp that still has me shaking my head in wonder. And more recently, I was at my local hifi store and compared a Grado SR325x, Sennheiser HD600 and an Aune AR5000. The salesperson must've heard me laughing in disbelief when I had the Aunes on my head. I never had such a big smile when taking out $400 cash out of my pocket for a purchase.
