New AT cartridge thoughts/question

~@bkeske, I think he is looking for a mechanism to placate the population. He is in business to sell cartridges. He can not just come out and attack people's sensibilities. Another thing. This is not rocket science. Phonograph cartridges are very simple devises. Electronics engineering and even speaker design are far more complicated subjects.
Peter's experience is in building and repairing cartridges. I would not know were to start in that regard and my hands are too shaky anyway. His designs are borrowed from others with some embellishment.  

@bkeske, If break in does not exist which, is essentially what he is saying for his cartridges at least then what causes it? Without saying it he has implied that it is psychological. As for his other possible mechanisms they are laughable. Styli do not rotate if glued in correctly. They are (or should be) permanently fixed to the end of the cantilever by one means or another. Azimuth does not change in moving coil cartridges. The coil is pulled firmly against it's rubber suspension which is fixed to the posterior pole. In order to change azimuth you would have to release the wire, rotate the coil then pull the wire tight again. He is patently trying to trumpet his design by belittling others which is a methodology he frequently uses in his lectures and the most significant reason as to why I probably will never own one of his cartridges. 
The changes that might occur in a cartridge are relatively minor and do not explain the degree of change many people hear. I had a Clearaudio Talisman for a while. It has a reputation for being a bright cartridge, too much high end. It was but after a while the brightness seem to fade. Ok I thought. The cartridge is just loosening up. Eventually I switch back to another cartridge which for a while seemed dull but then it sounded fine. On switching back to the Talisman it became just as bright as when it was new. The only thing that was breaking in was my mind. We get use to things, the new norm. 

bkeske, How would a stylus "adjust itself." I could understand the suspension adjusting itself. Thing is why would this always make a cartridge sound better? Why not worse? 
Ledermann thinks "break in" is purely psychological. He avoids saying it directly for obvious political reasons. Since I have nothing to sell I don't have to be political. Human hearing is incapable of detecting slow relatively minor changes in sound. It can detect abrupt changes above a certain threshold. It is more likely that we just become use to the sound over time so it becomes our new reference. Have you ever switched back to an old piece of equipment and gone "YUK?" "How could I ever have listened to that and I use to think that sounded great." You had gotten use to it. 
On the other hand I can alter frequency response +- 1 db any which way anywhere between 20 Hz and 20 kHz and none of us would know it. 2 dB and I think most of us could identify the part of the spectrum that was being modified. 3 dB is unmistakable to anyone. 1 dB is a pretty big change but to hear it you would have to go to 2dB which is huge. I doubt anything "breaking in" would make a 2dB change in frequency response.
