I had a P5, since sold. But I had the Groovetracer reference
subplatter and can echo Jetrexpro..the noise floor dropped.I
didn't care much for the Groovetracer acrylic platter, but
the new delrin platter they make was superb. A marked
improvement over the acrylic and stock glass. If you're a tinkerer may I suggest the dual pulley made by Michael Lim. Of all the upgrades I made it was the most dramatic. Noise floor lowered further, wider sound stage , tighter bass. As for the white belt, I found one on sale and got it to have as a spare. I didn't notice any change whatsoever when I tried it.
