Class D amps are always lively.

Sorry, but that's a generalization that does not hold true to my ears, based on hearing several in my system and at a few audio shows.
I suppose one's definition of lively is important to the discussion. If you're talking about frequency extension and clarity, then the Class D amps are lively. Other than that, the Class D amps I have heard were anything but lively.
