Well said.
The option I like is to have a fairly neutral amp (β22) and source, and then if I want a euphonic flavor now and then, that can be accomplished with a euphonic headphone. The modded Orthodynamics fit the bill there for me, and there are times when I do like that flavor.
Though I've yet to hear the combination, I assume that the β22/K1000 combo will be quite neutral for most of my listening tastes.
