some upgrades fo me on an NAD533 which is a cloned P2 have been:
Michel Technoweight (end stub and counterweight)
replaced feet with isopod feet/cones
TWL Strange Tonearm Tweak (search this forum for that one)
DeepGroove subplatter
Teflon arm wrap
DIY spotmat
Each change brought about noticeable improvements and together the sound has brought about better definition overall and on attack/decay, detail, dynamics, 'swing' aka PRaT.
