Magnepan 3.6 or 3.7 - The smart choice?

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.

You realize of course, that unless you buy the 3.7's you will forever be guilt ridden, have sleepless nites and many bouts of high anxiety. Just go for the 3.7's and put yourself out of your misery. As all audio people know, compromise need works.

reading through the above responses, i'm prepared to change my earlier vote and make it unanimous--go with the 3.7s. if you're as obsessive as the rest of us, it's worth the extra bucks to get the new-and-improved model (although, by the same logic, you should step up to the $14k 20.7s, which are even better). seriously, years ago i cheaped out and bought a car without the leather seats and upgraded stereo and spent the next five years wallowing in regret and self-loathing.
