Magnepan mg1.6 vs mg1.7 bass quality?

thanks guys for the response, i have owned the mg 2.7 10 years ago and was quite happy with the sound in our living room, would love to have the 3.7 but my current listening space is I think too small for it. 13ft x 16ft x 8.5ft ceiling. I dont want to dominate the entire room too much. If only I can replicate my old MG2.7 sound in a smaller space and a bit lower power. I used to have 600-watt 4ohm class A krell fpb 300 powering the 2.7, and was hoping the bryston 4bsst2 and the mg1.7 can duplicate that in a much smaller space.

any comments?

Keep what you have but get a sub

Lecram, I never had the opportunity to hear the 2.7's, so I don't have that as a point of reference. I agree the 3.7's may be a stretch in your room, but mine are in a room 15 x 19 x 8. Take a look at my system pictures to get a feel for how they look. The funny thing about the 3.7's is that they integrate with the room MUCH better than the 1.6's did. I was able to take most of the room treatments out of the room.
I'm not a huge fan of Bryston and Krell amps with Maggies. I do like the SS Cary amps (obviously), so you might think about that as another way to warm things up a bit. I still think the best move is to pick up a nice REL sub and see if that gets you where you want to be. You can snag a used R-218 or R328 pretty cheaply. Even cheaper if you go with an older REL.

Pass also seems to be a great match, "Then I tried a set of Pass Labs XA100.5 mono amps with the 1.7 which immediately had me revising my opinions of the speakers";

Once I added mono block power the speakers bloomed. They are thrilling now and much fuller sounding than the 1.6's . The new crossovers are made to do that. But if you have the 1.6's I would only change to the 3.7's....
