I own the 846 & W60, also. Haven't touched the 846 since recieving the W60. The W60 has so much more "tone" in the low end & low-mids. Not to mention a much smoother and extended high end. The W60 is so much more musical overall. It seems like a richer, more complex listening experience to me. The 846 has sub-low end and treble, by comparison, and that's about it. Just pointing out a differing viewpoint. Tastes vary.
