A decent compliance match between the arm's effective mass and the elasticity of the stylus suspension leaves both the arm and cartridge able to work in tandem(instead of against each other) to avoid generating unwanted resonances while the stylus tries to retrieve a clean signal from the groove. The AT95e works well in arms that have an effective mass of 10gm and above and the long exposed cantilever and square sides of the cartridge body also make accurate alignment to a protractor ( assuming the stylus is straight) fairly easy to achieve.
Substituting a better cartridge, but grossly mis-matching the compliance will probably yield a less satisfying sound as the stylus' tracking ability is compromised by a constantly wobbling arm on anything but the flattest records, or recordings that do not have sustained high amplitude low frequency content.
Using ported speakers with such a mis-match will need a subsonic filter to avoid uncontrolled mid-bass / woofer movement as well as waste amplifier power trying to reproduce the low frequency resonances that have nothing to do with the musical signal.
Heavy arms and high quality, high compliance cartridges tend to obscure the potential of the cartridge and arm to sound good.
Ditto low mass arms and high quality , low compliance cartridges.
The latter combination is easier to tweak as you can always add mass to the arm (blue tack , a heavier headshell etc. if the tonearm's pivot bearings are decent quality and the arm is reasonably rigid.
The former *high mass arm -high compliance cartridge* combination , not so easy to cure..
Get the compliance match right first, then accurate alignment to a *known* geometry , dial in downforce, antiskate , turntable levelling etc... then tweak your way further down reproductive chain... phono stage > amp > speaker placement etc
