Yeah, no matter how long the utopia has been burned in, open dynamics will never extend in the bass as well as a good planar, but outside of that, weight of the sound, and the stage size/3dness of the stage, I feel like the utopia is better in the other areas. Clarity, resolution, imaging and dynamics are all better but I don't think it's that much better in those areas vs the he-6 IMO. The utopia does have that brightish colouration as well which is due to the beryllium used for the driver, but a good warmish tube amp can IMO fix it. I feel like the same can be said for the he-6, but finding a good tube amp that can drive the 6 can be hard (any sugestions guys?, I'm looking at decware's speaker amps). That being said the fact that the he-6 can trade blows with a headphone 4X the price, is a testement to how good the he-6 really is (though the same can be said about a well modded hd 800).
