If that's how you wanna play, here goes :
There is significant weight to the air of the Utopia which makes it sound rather veiled and the soundstage is not exactly large either nothing like the SR009 and neither does the mids stand out in any way shape or form due to having a weird off timbre that makes mids sound way too thick.
Then I get to the elephant in the room, the bass, which is worse in quality. Quantity they are rather the same but for 1.5k less why not?
Oh and driving the utopia. If you have $4,000 to buy a headphone, which you obviously don't (Or that I can't tell if you do since you always say you can afford it but lazy to buy), you will wind up buying an TOTL amp it's simple as that.
However, I also found driving a utopia with the Questyle CMA600i sounds alarmingly way better than driving it out of a CHORD Hugo TT.
The treble in the Utopia is more sort of, meh. Whereas every single frequency band in the SR009 stands out and having a precise soundstage while having the right timbre makes it so much better, plus you don't have to buy the 007tii. No. The 727 will do. Apart from lacking oomph in bass department (I've been told SR007 does not lack it) the SR009 is heads and shoulders above Utopia
