Wow, you rank the SE846 higher than the Roxanne (universal or custom)? I owned the 846 for a good while. Liked it reasonably well for the time. Recently heard the Roxanne universal at Sound and Vision... and while it admittedly wasn't the longest demo time or most ideal conditions, I didn't hear anything to write home about really. It seemed a bit dead in the treble area. By comparison, I much, much prefer the highs of my ASG-2.5 (which is tops of my heap right now, even more so than the LAB 1).
Well the ranking is also based on my preference, I tend to like a more brighter sound signature than overly dark and bassy types
But admittedly I found Roxanne to be technically better than most.
