Aornic posted a very nice video and extensive written review of the Utopia over on Head-Fi.  I included a link below for the video review on Head-Fi.  It’s interesting that the soundstage is a bit constrained i.e. similar to HD600 series.

Pros: Extreme clarity and detail, easily driven, good build quality, not lacking in any frequency, dynamic and impactful sound, weight distribution
Cons: Price, only a 1/4 terminated stock cable included, stock cable heavy and unwieldy, bit on the heavier side overall
