There is absolutely no possible way to harm anything by trying one pair of ICs versus another between the tonearm and your phono stage. It is sad, however, that a company like audioquest, which makes audiophile interconnects, does not list the capacitance of their cables, if that is really the case. However, there is no way to do any harm by trying. Listen for high frequency extension. Use what sounds the best to you. Pay no attention to anything else or anyone else.
In a phono connection you generally want shielded interconnects, but whether that is really important in your locale is only to be determined by you. Shielding per se increases capacitance. So often there is a trade-off, if your cartridge is particularly sensitive to capacitance. (In which case you may sense a slight roll off of high frequencies, as suggested.)
