I would love to hear others opinions on the sonic trade offs with respect to choosing one or the other. I happen to use a dr. Feikert set up tool and it gives me the option of either of those three. (I don't recall whether the Dr. Feikert tool uses A or B for their 'Lofgren' - I don't think that it is indicated on the tool). For some reason I started out with the impression that lofgren gave me the best alignment throughout the whole (average) radius of a record, as opposed to maximizing one portion of the playback over and another. I happened to have been using lofgren . . . . but would love to hear some opinions here.
Which alignment option do you guys prefer?
