Raul, Before now, I thought your favored alignment geometry is Baerwald. And isn't Baerwald equivalent to Lofgren B, not A? Surprised to read here that you strive for A.
I think one reason this topic is controversial relates to a point that Raul made earlier: the tracking angle error and therefore any audio signal distortion created by TAE, is changing every second, as the stylus traverses the playing surface, while we listen to music. It may be very difficult for the brain to detect the audio distortions, because at any one moment in time, the distortion being generated by an erroneous alignment may be no worse than the distortion momentarily created by any one of the standard alignments, at a different distance from the spindle on the same LP. This could pertain even if, on average, we are best off with one of the standard alignments (assuming here Lofgren or Baerwald, since Raul hates Stevenson as much as he hates tubes). This business is not as simple as detecting and eliminating a distortion that is a constant.
