Breakdown of Turntable Performance


Over the years I've read numerous reviews of turntables, arms, platters, and plinths.  I always wondered how much these individual components contributed to the overall sound.  Here's my take:
Cartridge - 80%
Arm - 10%
Platter - 5%
Plinth - 5%
128x128jmarini2
I've obtained great results by isolating all 5 major components from each other. The controller, motor, flywheel, turntable, & arm pedestal, are all on there own platforms. Isolation & quality parts are key. BTW I can attest to Slaw's MyMat being well worth the investment. It is the best I've had on my table.   
Arm: 33.33%

Cartridge: 33.33% 

Table: 33.33%

or 

Pressing quality: 50%

Everything else: 50%
 

The requirements for the turntable depend on quality of the cartridge it has to serve.  I was very happy with my at-lp1240 til I had my AKG P8ES Supernova upgraded with a boron cantilever.  The upgrade made a huge difference in responsiveness, but the byproduct was the direct drive motor noise became much more noticeable once the stylus hit the vinyl.  It wasn't a problem for me before.  I'm now looking for a belt driven turntable so I can enjoy the cartridge more.
