Currawong has posted a review of the Utopia on Head-Fi. As with comments from other reviews of the Utopia, you must have a TOTL ecosystem to support these headphones. Poorly mastered recordings or average amping will make the Utopia miss its mark as a true top-end headphone i.e. Stax SR009. What this means is that you will need $4,000 for the Utopia plus a chunk more change on your amp/DAC/cables/power purifier/turntable/Hi-Res (and well mastered) media. My ears are no longer capable of supporting this sort of expenditure.
The review includes comparisons with the Sony MDR-Z1R, HD-800, MrSpeakers’ Ether Flow and the HiFiMan HE1000 V2.
Pros: Incredibly resolving of music and upstream components. Incredible driver speed and ability to perceive width, depth and the movements of sounds.
Cons: Incredibly resolving of music and upstream components. Sound a bit closed-in if not used with a top system. Bass a bit weak and has phase issues.
