Just trying to get a bit more of an idea as to what the issue is. First what do you think is lacking in the current system? It would also be helpful to know what the rest of your system is, what you listen to, and what is the room like. You have a great speaker, which does have a different sound than the maxxs. If it is, like cars, that you just want a new or different model, then by all means change. On the other hand, if you are looking to reach a certain goal, then this may not be the way to go.
Either way good luck
