"" If memory serves the bearings in the SME 5 are the hardest commercially available. The bearings in the Triplanar are not commercially available...."
That I know SME never stated about. Where is your link on that precsie tonearm SME characteristic?
" Specifically as it was explained to me by Herb Papier, the problem he ran into was that over a period of years he noticed that many arms needed to be readjusted. He found that the reason was that the bearings would fail over time in the field- due to use and minor abuse the bearing points would blunt. "
many arms? which tonearms and after how many number of years?
" SME deals with the reliability issue by having physically larger bearings. So their arms tend to have more friction..""
SME ? where are the facts that can prove it.
" tend to have more friction. ", again where are the facts that can prove it and how much more friction. Btw, which its original friction levels? which SME model are you refering?
Seems to me that you are spreading false information against a very well regarded tonearm manufacturer as is SME and you are an audio item manufacturer ! !
