Former Maggie owner here...........
I would suggest you buy the Internet direct $300 center channel and see how it works for you, I ran one for 2 years and never felt I needed more, the CC3 is a lot more cash for only 20 extra HZ, the budget center goes down to 100HZ and the expensive CC3 does 80HZ if I recall correctly.
I ran mine with a Parasound amp, 200watts used can be had for around $500 and they are a high current line that can handle all but the loudest full range Maggies.
Space behind them as others noted is really, really critical and if you cant pull them out far you need to atleast break up the backwave with odd shaped items behind speaker, like diffuser panels.
If I can be of any help contact me anytime..............good luck!
