To me these two speakers are like apples vs oranges. Totally different approaches to design, totally differnt flavors. Each has its specific virtues and weaknesses.
The 1.6s might want highercurrent and/or more refined amps. And a fast sub like a Nola Thunderbolt would give you a lot more impact. If you haven't treated your room, fersher do that. You have a nice preamp that should be very dynamic with ample bass. There are some things than planars do well that are very hard to give up. (I had Maggies for years.) Try to audition a sub and different amps before you get on the speaker merry-go-round. The 1.6s are hard to beat for the money.
OTOH, faced with a large room and similar problems, I must confess I went back to cones 'n domes a few years ago, albeit not VRs, and the speakers I did end up with retain many of the planar-like charactaristics I liked with my 1.5s (Alons, now Nola.)
After trying amps and sub(s) with your 1.6s, if you can't get happy with them, listen around to a variety of speakers. You might also want to consider VMPS speakers with their ribbon tweaters in addition to others already mentioned.
