Al,
From the things I have read, and the cart designer I have talked to on the subject of that resonant peak in frequency response, that peak is waaaaaaay outside the audible band. However, the problem is that it is so large, that just like a really big earthquake, it can cause problems a long distance away, and so can stress phono stages at levels within their reach (which would still be outside the audible band), which causes performance issues inside the phono stage.
The numbers I have seen of that resonant peak would suggest that it is like no earthly peak in comparison but magnitudes higher in comparison from the sea level starting point of the audible band. As I understand what you are saying, cart designers are effectively moving to the foothills of Mordor (and raising it ever higher) in order to make their badly insulated houses warmer.
Then again, I may be misunderstanding this...
