Loved your account of discovering the Obligatos, @Mouse
I had them for a bit (until I manhandled them over cleaning, my bad) and they were certainly warmer than the Evah Pirazzis that preceeded them.
Also tried Violinos as a less costly version of the Obligatos. According to the manufacturer, they have the exact same core, the difference is in the metal wrapping.
Of course, no wrapping is going to make strings sound warm and wonderful without good bowing... seems like your work on that is paying off
Since we frequent the same "candy shop", you've probably seen this Obligato review by Michael O'Gieblyn: Obligato review with real time graphics of the harmonics. Posting it for those who haven't.
Hope your ménage à trois (you, Rudolph and the Obligatos) continues!
