The Pfanstiehl 4822-DEE only really stumbles on hot overmodulated grooves, which a lot of cartridges/styli do, incidentally. I often run mine right at 1.5g at the upper limit with the brush and antiskate set to 2.5g, which is what your controls will look like if you balance the arm without the brush. If you balance the arm with the brush on, your VTF scale will read 2.5g and so will your AS dial, but you will know you are tracking effectively at somewhere around 1.5g. So, well within prescribed tracking force of the original 822-DEE aka D6800EE, which the Pfanstiehl truly emulates.
And, at least with a little twist of the VTF dial for the records that you know are hot, the 4822-DEE will reward you with no sibilance. Not all cartridges do that, either. AND, the 4822-DEE has such a high clearance between the bottom of the stylus grip and the record surface, it will track moguls without hopping around. I have a couple records with edge ripples that are unplayable by any other cartridge, period, even Stanton or Pickering cartridges with original Stanton styli. I really need to capture this on video and YouTube it. The one and only other stylus I have that does this well is a D81 that was retipped by Expert Stylus with an overly long sapphire cantilever. Pickering styli are too wide, as are most cartridges in general, to be able to handle the edge ripples without being knocked. The unique narrowness of the 680/681 etc. styli contribute to its heralded tracking prowess. Add a long cantilever with a lot of clearance like the Pfanstiehl, and there are records that can be played that otherwise would be useless.
