Cerrot, have you tried load resistances that are much lower than the 47K you are using? And have you tried various load capacitance settings?
Along the lines of Ralph's excellent post, those values will directly affect both the frequency and the amplitude of the ultrasonic resonant peak he referred to.
It's hard to be more specific or quantitative without knowing the inductance of the cartridge, but after plugging various values into the calculators at the Hagerman site I wouldn't be surprised if something in the area of 10K to 20K, and the minimum possible capacitance setting, proved helpful.
On another note, I want to say that it seems to me that a lot of the reason that opinions diverge on the objectionability of lp tics, pops, and surface noise is probably that people are listening to different kinds of music. Assuming equal pressing quality, those noises will obviously be much more noticeable and objectionable on a well recorded classical symphony, with wide dynamic range, than on a dynamically compressed rock recording having a dynamic range of just a few db.
