Keep in mind not necessarily all the amps on the list are "greats" anymore, but were perhaps very influential on the industry in some way. Obviously there's a bit of subjectivity to the list too ; Neil Gader put the Rotel RB1090 on the list as well as the Plinius 8150. Not sure I agree with the choice of the Rotel over something like the Adcom GFA555 in terms of affordable influential powerhouse amps. The Adcom most assuredly made its way into more homes than the RB1090 and likely played a significant role in paving the way for future products from NAD, Rotel, Outlaw, Emotiva, etc. Not sure about the Plinius either. In the grand scheme, I would put the Bryston 4B on the list for bridging the gap between pro audio and home audio in a way no other amp (I can think of) has done with equal quality, reliability, or style. If one were trying to put another integrated on the list, I'd probably put the Naim NAIT on the list over the Plinius in terms of significance.
It seems Neil was intentionally trying to stray from just picking the same obvious choices as the others : NAD 3020, Dynaco ST70, Phase Linear, etc. etc. but missed the mark a bit with some of his choices....though they make for an interesting, if not somewhat controversial list.
I think the list has all the major influential designers covered though - David Hafler, Bob Carver, Saul Marantz, John Curl, Nelson Pass, James Bongiorno, Gordon Gow, etc (I'm sure I've missed a couple more greats, many of whom were "students" of those listed)
