RJB Asterion vs Audio Physic Spark.mov 

Wow even thru my headphones it's very clear that the Asterion is way better.Just more natural and balanced,especially in the midrange.

@weskoki yes the Asterion is more balanced. The sparks lacks bass and the midrange is so dynamic it sounds unnatural at times but it makes up for this with superior soundstage. (This mono video does not capture the huge soundstage that is projected by the Sparks)
