Magnepan 3.7's versus 20.1's?


Anybody here had the chance to compare the new Magnepan 3.7s with their longtime flagship 20.1 speakers?

Anyone can recommend an ideal sub for the 3.7 as I'm used to the Wilson Audio Puppy bass. Very low and dynamic and how do I connect it to my Goldmund Telos 3.9? Like the speaker but really need a sub to go down to 20hz.
"Available" but not sure a dealer actually has these yet... Aynone know of an actual Magnepan dealer that has a set of 20.7's?
Called Magnepan today and asked when 20.7's would most likely hit showroom floors; answer, approx. one more month...
