Magnepan 3.6 or 3.7 - The smart choice?

I was offered a good deal on a demo pair of 3.6's and bought the 3.7's for full retail. If you can pick up 3.7's for $4K do it now. Too me, the 3.6's suffered from some of the same limitations as my 1.6QR's. The 3.7's are just way more speaker in some important ways. As you see from Loomisjohnsons post above, many people, whose opinions are just as valuable as my own, just don't hear the same thing I heard. I guess the good news here is you can't go wrong. You are being offered good prices on both speakers.

I owned 3.6s and 3.7s.
IMHO 3.7s are quite dramatically improved over 3.6s in every way.

if the $4k for the 3.7s are within your budget, I would strongly suggest going with the 3.7s.

couldn't help it went w/the 3.7's.
by the way have any of you felt the 1.7's sounded a little peaky on the quasi ribbons as opposed to the full ribbons on the 3.6 or 3.7?

p.s. now i'd like to find that hypothetical deal for some used maggies. i realize it will cost me more than i could justify paying but, as i said, i was truly wondering about the wisdom in spending basically double the price of 6's for 7's. ty everyone for current or any future input on this thread. i believe i could be more than happy with either choice. i obviously am a maggie fan. 2 weeks ago sold my IIIa's after & going thru maggie withdrawals. to tide me over i purchased inexpensive, but not offensible, box speakers to resell when my quest is realized.
