anemic was the right word used. As a headphone all by itself, it is inherently bass light. The same amp it shines on will most likely make any other bass light high impedance headphone warm. You'd be hard pressed to find a non-grado over 1k with less bass. But what is there is great and worth trying to bring out.
The Utopia will be less picky, is easier to drive, and is naturally responsive to what the recording has. But its resolution and details really shine on a good amp with lots of detail.
The way you describe the sonic characteristics of the Utopia, makes me want to save up for these headphones. Perhaps sell my liquid Crimson, to help pay for these marvelous headphones. But for now lol, I will just read the impressions and dream a little dream.
