"Too thin for my tastes?" I used to own the DT and didn't find that at all, and the Passion is a whole other story. It's what makes this a great hobby. I'm a jazz man and the Passion does it for me in spades. The Passion is toasty, airy, sweet on top, detailed and enough current for my system. Everything, of course is very system dependent and I didn't have the same experience, listening through the same stuff as Arthur. Remember there's a cdp, cables,speakers and a whole bunch of other things that affect the sound as well. My A/Bing wasn't, truly, a fair one, but never the less, I believed the Passion was the deal for me. You're comparing some killer stuff. It's going to be a judgement/preference call. All I know is my Audio Aero Prima and Passion are a match made in heaven. Very sweet for SS. Good hunting. warren
