I have listened to your tracks over and over, and beside distorted sibilance, i THINK the midrange (voices) sounds a tad harsh/brittle/distorted at times, like inner-groove distortion (since I dont have a copy of this on hand, I dont know if the other tracks at the beginning of the records sound better or not, but I have a few discs from the 70s and 80s sound like this at the end of the record, while other discs show no sign of this inner groove distortion)
Also, the Benz and the Ortofon (which happen to have very similar specs regarding compliance, stylus tip/radius) which you have set up carefully, behave pretty much the same playing this track, I doubt that these distortion is a result of misalignment.
These cartridges have output around 0.3-0.4mV, so they are not overloading your phonostage to create these distortion either
I have a strong feeling that this is just your copy (other's might be OK), or your arm/cartridge prone to innergroove distortion.
It would take a highly resolving cartridge mated with an appropriate arm (doesnt have to be expensive) to conquer these distortions.
My Audio Technica AT33PTG with its tiny stylus tip mounted on a SME 3009 Series 2-non improved is an excellent, excellent example, and so is a Clearaudio Maestro on a Moerch DP-6.
Please keep us updated with the result of your turntable/arm checkup and LP testing on other systems.
