Some questions:
What settings are you using on the SimAudio phono stage? With a 2M Blue I would expect the best settings to be:
Input impedance: 47K
Gain: 40 db
Input capacitance: 0 pf
The recommended load capacitance for the 2M Blue is 150 to 300 pf, which will probably be provided by the capacitance of your phono cable and the tonearm wiring. Given the very high inductance of that cartridge (700 mH), if you are not using the minimum capacitance setting of the phono stage ("0 pf," which in reality is probably a few tens of pfs), you would be moving a high frequency resonant peak in the overall response well down into the mid-treble region, which would likely add a good deal of emphasis to tics and pops. And that would be especially true if you are using either the 330 pf or 430 pf input capacitance setting provided by the phono stage.
Also, if the gain of the phono stage is set to something higher than 40 db it is possible that some of the crackling you hear at times may actually be the result of overloading the phono stage or the preamp or integrated amp.
Finally, what tracking force are you using? It should be in the area of 1.8 to 2.0 grams.
