Regarding soundstage. I was listening to
Passion, Grace & Fire, one of Stereophile's 2017 Records to Die For.

Switching between the Koss ESP950, the T1/Crack, and the Utopia/Taurus, there is no doubt to me that the utopia has a different soundstage relative to these other cans and amp combinations. DAC for all three is a Bimby. the sound from the Utopia is "fuller" and possibly a little polite.
For this album, I prefer the T1/Crack combo. I have a Mjolnir 2 coming, and I will try that with the Utopia, as well as some decent tubes.
No matter what, this album is incredible.
