Not necessarily so.

The two types of cartridges that we are speaking of M44 and SPU have
significantly different weight and stylus compliance so the arm
mass/cartridge compliance LF resonance will show greatly differing LF
resonance frequency and Q of resonance.

Unless controlled it will show itself as audible defects when trying to
do a declick pass on the soundfile and here the M44 is at a disadvantage
compared to the greater mass and lower compliance of the SPU.

What happens is that at LF having a large subsonic component makes the
software produce artifacts that makes it sound as if there´s a worse end
result.

Controlling the LF resonance in various ways to lower the Q and getting
the resonance frequency at say 10 to 15 Hz together with HP filtering
BEFORE doing the declick pass makes the end result almost identical in
my experience.
