Hi Tobes,
yes, I think it'd be just good to get some other perspectives on thatsubject.
There is one thing that struck me (always trying to find some explanation) when a lot of these MM where in use NOBODY, but for a few audio enthusiasts, knew much about VTA, never mind the other alignment subjects. Might this just have contributed to some 'lesser' regards for those oldies?
A guy that spend big $$$$ (at the time) on an MC and SUT (A MUST AT THAT STAGE) might just have been more 'into it' all...
Of course phono-stages have improved a lot also. If it was not for all of that, including really crappy TTs, the CD would NEVER have had much of a chance and gone the way e.g. SACD is going. How else to explain it.
Back to your P77, according to the 'Brothers' (straight from the horses mouth!) that P77 needs positive VTA a-plenty!
That's why it can sound the way you describe it, if run on e.g. a level arm. Your exact sound description of to small an SRA!
Greetings,
Axel
