I had the opposite impressions that you are talking about above...
I used the Utopia with many different amps, incuding the Auralic Taurus Mk.II, and Headamp GSX mk II, different dacs, and sources, and the results were basically the same...
Forward, in your face, tense, closed in sounding, harsher than the HD800 on some material, a slight metallic (beryllium?) coloration, bass wasn't too impressive either.
It did do some things well...dynamic punchy, high resolution, transparent, but it did not win me over and I don't think it had anything to do with the amp.
A let down for a $4,000.00 msr headphone, imho. Maybe I had a defective pair?
The HD800, 800 S, and HE-6 modded, are much better values.
To each his own
