Well at first I thought it was an okay unit. Nothing amazing, or really game changing about it. But when I did a head-to-head with my old reference 3, it sounded grainier in the mid range, and overall not nearly as transparent and detailed. It seems I once again got caught up in the head-fi hype machine... Choo choo! Unfortunately, some of the people who are hyping it really are lacking in audio knowledge.
