Magnepan 3.6 or 3.7


I have a chance to buy mint 3.6s for $2,000 or mint 3.7s (not "i") with mye stands for $3500.  Both cherry wood.  I currently own 1.6s.  Please weigh in.

Thanks in advance.

If you can stretch the budget ever so slightly, the 3.7's would be a much better buy. The Mye stands are definitely a big improvement. Also, the 3.7's are going to keep their value better if you ever decide to upgrade in the future.
I do not bi-amp, but I do bi-wire my 1.6's, which cannot be done with the 3.7's. I assume that is not a big deal anymore if Magnepan no longer offers the option, due to the new xo design?
Leaning towards the 3.7's based on the early responses. Keep em coming!
I love my 3.5s.  I loved my SMGas, .6s, 12s and 2.7s, but wouldn’t go back. I believe with Maggies, every generation brings improvements.  Get the newest you are comfortable purchasing.

Thanks everyone for your feedback.  I've decided on the 3.7s, based on your responses.  I live in Iowa so it's easy for me to drive them up to the factory for the upgrade should I choose do do so.

Once again, thanks!
