however even Wendell Diller of Magnepan has said that the difference between the 3.7 and the 3.7i is very subtle. So, I can keep what I have, upgrade to 3.7i, or sell these and buy a brand new pair of 1.7i
@krelldreams Based on what I have heard from dealers (and Magnepan) the difference between the 3.7 and 3.7i is much smaller than the 1.7/1.7i difference.
