Hi Wid,

Not from late 2002. The crossover changes in the M80, which resulted in a more linear and audibly smoother upper-midrange response, were implemented in mid-2003, after a series of double-blind listening comparisons of an M80 "A" version (the original) and the modified "B" version. The "B" version won the tests by a slight but statistically significant margin and the changes were implemented immediately in on-going production of the M80s.
