“Trickle-down effect” is an expression manufacturers often use to describe the application of lessons learned in developing a flagship model to the development of lower-priced products. However, according to Wendell Diller of Magnepan, in developing the new Magneplanar MG 3.7, what has taken place is a trickle-up effect. (Wendell celebrates 36 years marketing Magnepan this year!) The lessons learned in going from the MG 1.6 to the MG 1.7 were applied to the more expensive flagship MG 3.6, with what he says are results that represent at least as much of an improvement as the change from the MG 1.6 to the MG 1.7. I’ve been quite impressed with the MG 1.7 on previous occasions, and listening to the MG 3.7, driven by Bryston electronics at T.H.E. Show, made me think of the MG 1.7, except for greater bass extension and dynamics. Magnepan has kept the price at $5495$5895/pair, which must represent a bargain for a planar speaker of this performance and pedigree. Standing proudly next to the MG3.7 in JA's photo is Mark Winey, son of founder Jim, who now runs the Minnesotan company.
