Henry, Don't you think that Fremer's results with digital recordings made with the Thales vs "normal" pivoted tonearms could as well indicate a failing of the Thales, in terms of its engineering? For example, someone wrote that it has an offset headshell and thus generates skating force. That right there is what you would hope to be rid of, if you are going to the bother and expense of establishing tangency across the LP. (I did not know that about the Thales and was disappointed to read it here.) I think much of the distortion that some claim to hear with pivoted tonearms vs LT ones is due to the constant variations in skating force across the LP, rather than to tracking angle distortion. Then too there is the issue of bearing friction.
It would be more telling if Fremer or one of us would do a double-blind digitized comparison of the Trans-fi or the Schroeder LT, vs a conventional pivoted arm.
