I've found a solution to my dislike of screechy highs. And it was right in my cartridge drawer!
I installed my very old Grace F9 body with a Soundsmith RS-9E stylus assembly (plugs in). The stylus assembly is constructed of an Alimunum Cantilever and a nude elliptical diamond stylus. Installation was on my Denon DP-57L table.
I've forgotten how difficult MC alignment can be and how easy this MM cartridge was to align. Separation, azimuth, anti-skate, VTA, and VTF adjustments were straightforward and simple.
The sound is very beautiful and smooth. I love the midrange. Bass is surprisingly full and has detail. The FR curve shows gradually diminishing lows by about 5dB from 100Hz down to 20Hz and a very small rise above 10KHz of about 2 dB. Separation is about 27dB. I set the VTF to 1.25g (the old Grace recommendation was 1.2g). SS doesn't spec the compliance, but if it is true to the Grace F99E it is high compliance. The stylus is almost brand new. No screeching.
This issue is settled for me...for now.
