Tralucent 1Plus2 (revised)
Rhapsodio RDB Mini / Tralucent 1Plus2 (first version) (depends on the DAP synergy which pulls away)
Rhapsodio RDB v1
Vision Ears Stage 3
Astrotec AX60 / DN-1000 (close call)
Triple-fi 10 (needs silver plated cable to shine)
Many of those are hybrids, and somewhere in there Unique Melody 3X could be included, however it wasn't for me, unfortunately. There's a few others like Sony XBA-3, Vsonic GR01, Klipsch X10, R-50, B2, VC1000, H-100, however they're below the others listed and my list was becoming a little carried away.
