In the Thread: Lamm ML2.1 "No longer available"?

He did note that the ML2.2 uses a different OPT, and also that it uses "less feedback" than the ML2.1 (which AD owned for several years). I wonder what this means, "less feedback"? Why would Lamm mess with that very effective scheme? Does he just shunt some voltage, or did he really change the circuit? I see the 2.2 uses all the same tubes...
Of course, no talk about plate loading, with bias or output taps, with his various "mid" and low efficiency speakers, all running FR. It is no surprise, he says he prefers his PP (pentode, I think) Shindo amps driving his own speakers (FR). I was somewhat surprised at his "comparisons" of the 2.2 to the 2.1, and most surprised that he does not say outright that everyone should immediately chuck their "old-news" 2.1s and run out to buy the "newer-and-therefore-better" 2.2s. I don't remember if he said anything about the "limits" of SETs in general, but it has been my observation that, for some unknown reason, they seem to expect "more" from expensive SETs...
