Differences in newer Meadowlark speakers

I recently had to sell my Dunlavy 4a's and was looking at the Meadowlark line. Inquiring on the original Blue Heron's, a dealer said that they were a bit more musical than the Dunlavys but not quite as dynamic. I have never heard any Meadowlark speakers and will probably never get an audition but I do like the design philosophy and thought I might gain some insight here. I was curious If anyone had any experience auditioning the older Heron-i or Blue Herons vs the newer Nighthawk or Blue Heron 2.
