You can search the archives, this topic has been covered many times before. IMHO, the Models 2/6/8/9 series of the mid to late 90's were when Jeff Rowland was at his best as a designer. Earlier Rowland efforts were warmer, but lacked the definition, while later Rowland efforts became even more revealing, at the cost of musicality. The Models 2/6/8/9 were the sweet spot as far as balancing musicality with definition, again, that's just my $0.02.
