I am still loving mine. Like a true audiophile, I have still been searching for something better. I picked up a Meier Audio StageDac and Concerto headphone amp. These are two separate units. Honestly, I have been going back and forth trying to decide which setup sounds better. On certain songs it sound like the Meier equipment is better, and on others, it sounds like the Source. BOTH sound absolutely fantastic in all genres. I think the Meier is slightly better with classical and jazz, while the Source is slightly better with rock. I've probably spent 5 hours comparing the units, and still need to do more before I decide what I am going to keep. I might decide to keep the source over the Meier even if the Meier equipment ends up being slightly better due to the portability of the Source.
There is just no way you can go wrong with the Source.
