You are correct Bill... good memory. The Motion 60 way outperformed the Motion 40, though I did not hear them side by side. The Motion 40, with good Subs, would be a decent performer, I think.
Found minimal difference between the MA Silver 300 and 500... still preferred the larger of the two.
Between the Silver 300 and the Motion 40, I would say no contest and happily listen to the Silvers.
