What the load resistor does is three things: it detunes the resonant peak I mentioned earlier, thus eliminating the RFI and it causes the cantilever to be stiffer, possibly reducing the ability to trace high frequencies and certainly affecting the mechanical resonance of the cartridge and arm combination.
So you solve a problem for a phono section with a design bug, in exchange for introducing possible tracking issues. Not a good set of options IMO.
Since almost all MC cartridge manufacturer provide recommended minimum loading resistance, and usually the value is 10 times higher than the cartridge coil resistance.
My question is how significant that affect the cantilever to be stiffer and introducing possible tracking issues, OR its effect is negligible?
And may I ask how you fix that issue in your phono stage design?
