I agree that the over-simplified methodology of this survey is highly flawed, but I'll give it a shot.
Many of the following companies are long since out of existence (in a couple of cases, VERY long since), but given that Audiogon is a place for buying and selling used equipment it seems reasonable to include them:
Acoustat - 5
Antique Sound Lab - 4
Audio Research - 9
B&W - 7
Carver - 4
Classe - 8
Grace - 7
Grado - 7
Infinity - 6
Magnepan - 8
Marantz (the original company, under Saul) - 8
Mark Levinson Audio Systems (the original company, pre-Madrigal) - 8
Paxthon - 5
Pentagram - 6
Radio Engineering Laboratories - 10
Rotel - 4
SOTA - 7
Stax - 8
Tandberg (top-end cassette decks) - 9
Tandberg (other) - 5
Thiel - 5
Threshold - 6
