I went up to The Source yesterday and compared the Utopia to my modded HD800, and briefly to the HE1000. I was using a WA5 with a QP1R as source/dac. It is a smoother/lusher sound than HD800, but I thought it was better than HE1000 in this regard, which I view as too soft/smooth/polite. The macrodynamics were impressive - it gives the music a large sense of scale. The bass was a little higher in quantity and more extended than HD800, but also softer. Again not as soft as HE1000. My biggest problems were with the midrange and instrument separation. I felt it was lacking in midrange clarity compared to HD800 and instruments are more smeared together. So its not going to unseat HD800 for me. It's not quite as comfortable as HD800, but I found it plenty comfortable enough. I didn't notice the weight as an issue. Build quality is good - it feels solid. Thank you to @TSAVJason for arranging the audition and William for hosting us. The Source has an impressive collection of high-end headphones - anyone in the area should check them out. Edit: After hearing the Utopia in my home setup the midrange clarity issues I was hearing at first are gone, and I found the Utopia to actually be more resolving than HD800. HD800 still wins at soundstage and separation, but it is not by a lot, and Utopia wins at dynamics, bass, resolution and overall tonality. Based on this I have to reverse what I said earlier and declare Utopia the overall better headphone. Well done Focal!
