I agree with Wendell (Narrod). A better matching cartridge would help.
Also I have found that upgraded "to the max" the Planar 25 is hard to beat. The upgrades you mention (machined sub-platter, new counterweight, Cardas re-wire of arm, acrylic platter, Boston Audio platter mat) ALL make a huge difference.
