My only DAC/Amp which I am already happy with is an iFi micro BL, but have the D90/A90 on the way that will hopefully be here next week. Although different as the Dragonfly, your post gives me hope that I will see a noticeable difference too.
Haven't heard the iFi product line but the instrument separation is noticeably better compared to the dragonfly and the sound stage is wider. The treble has more sparkle, but the overall tone is more neutral.
I'm actually not sure if I prefer this over the dragonfly which sound more musical to me albeit lacking the details. To give you a weird example, I prefer watching movies in 1080P as I find the additional details in 4k distracting me from enjoying the movie (if that makes any sense). These are just my initial impressions of course.
What cans do you plan on running them on? I'd love to know your impressions on the A90 once you have it.
