Glad to help.
Reviewers in general have a propensity to be over enthusiastic of the equipment they review. However, there are a few good ones out there that I trust. I especially appreciate Doug Schroeder of Dagogo and Art Dudley of Stereophile....
I can't overemphasize the need for a good amount of power/current for the Magnepan. 100RMS into 4 ohms sounds a little light to me, but I'm unfamiliar with Rogue - although I understand they are very nice.
My .7s are powered by an EMOTIVA XPA-2, 500RMS into 4 ohms.
The basement room is irregularly shaped, but the width of the area where the Magnepans are situated is about 10 ft. 3.5 feet off the front wall, 7 feet apart, the listening/watching couch is about 7.5 feet from the speakers. If you intend to forgo the use of a sub, then the size of the panels will make a significant impact on bass response. I've also been told that the distance from the front wall significantly impacts the bass response. IF you have a larger room that can accommodate the 1.7, then maybe you could consider them. I recommend, if feasible, audition them in your room. Their clean, open soundfield is very musically enjoyable. There are many forums here and elsewhere regarding all things Magnepan - with much greater experience/expertise than I'm able to offer...
All the best and good luck.
