Looking for input on Legacy Audio speakers purchase.

I recently purchased a c2700 and mc462.  It wasn’t my original plan, but I am thrilled with the combo so far.  It’s not the old McIntosh sound for sure,  Its detailed and yet still smooth and not harsh.  Really really good.

I am a fan of both legacy speakers you mention also.  There is a very good chance if I didn’t have my Salk SS 12s, I would have the focus SE.  
I think it would be a great combo with the 2700.

The Aeris and wavelet will also be great.

I will say the DAC2 in the 2700 is fantastic.  

I think you have to think about if you want processing and room correction via your 2 channel pre amp or not.  The 2700 has more detail than many tube preamps I have heard, which is great yet does add some body and creates a big soundstage.  I love it.

 The wavelet is with room correction is likely to be a bit more precise.  Though the  Aeris speakers do sound big.

the c2700... well no debating it looks great!

15 x 21 isn't tiny by any means.  Plus, you have those 611's on tap.

I think unless it's absurd, the whole "too big for the room" thing is overblown.  Heck, if it's a room in the basement, or carpet and padding over a concrete foundation (like many including mine), sometimes a bigger speaker even helps.  I don't like running subs with my 2 channel, and I want the speakers to move some air.

I don't think either of the Legacy Speakers is too big for your room.  Heck, if it's the Aeris and Wavelet, room correction will fix (potentially) some of the errors.

Personally, and freely admitting it is in part due to my fondness for the C2700 that I just picked up - I think the Focus SE and C2700 would be a blast.  

Screw the room size thing.  I have Salk SS12's with a MC462 in a 13 x 17 room.  The SS12's are no delicate flower and can move some air and play down low.  Love them.

I run bass traps in the rear corners, absorbers at the 1st and 2nd reflection points and the room is a finished basement (so concrete with carpet and padding).

Sounds fantastic.  (I really do like the C2700 and the internal DAC.  I was frankly a little concerned but now after a week it's just awesome).

You can't go wrong with your choice.  No substitute for displacement.  You may not want it all the time, but it's fun as heck when you want it.
