Papermill, Thank you for the comments they are useful. I have a Rogue Sphinx V.1 hybrid integrated amp which is 100RMS, and supposedly more into 4 ohms. I have read in the separate reviews in Stereophile and TAS that depending on the room size, 100RMS can drive Maggies .7 well enough to sound full, and even reach down to 45 Hz
This claim was made by Herb Reichert of Stereophile who is a overly enthusiastic and therefore needs to be taken with a grain of salt. In his review, he drove the .7 first with the Rogue Sphinx and was a happy camper, but in the end he fell back on his favorite amp, the Vinny Rossie LM218 integrated which is about $4300. Therefore, I don't really find his reviews credible or the method he uses to review speakers by changing amplifiers to a more expensive and possibly better sounding.
Nevertheless, I am just looking for a speaker that is smooth and enjoyable to listen to despite having to sacrifice some low bass. BTW, what is the size of the room your .7 are placed, and what type of amp are you using.
I am not wedded to the Rogue Sphinx, especially since they made important changes to the model about 8 months after I bought it. It is now the Rogue Sphinx v.2 BTW, to upgrade from v.1 to v.2 is $400. plus the cost of round trip shipping That would add $200 extra because I live in Los Angeles and Rogue is located somewhere in Pennsylvania. I don't find this to be so-called customer friendly.
