It depends on your associated equipment, your room and your ears.
Getting the right fit with your room with speakers having the bass of WattPuppys and Maxx's is such that the Maxx's could ironically prove to be a step backwards. If you have a large listening room, this is less of a concern (or no concern at all).
With either of those speakers, assuming your system is set up properly, you could be expected to hear the difference between the old and new versions of the EMM gear on unamplified acoustic music. Whether you could hear it on rock, etc., is indeed a good question.
There are many, many threads addressing the issue of what's more important, speakers or front-end equipment. That issue will not be settled here.
Pleasant dilemma, in any event.
