I recently installed the classic platter upgrade and it was worth it. Im using a vpi TNT 6 w/c came w/ the clear acrylic platter.I was not satisfied w /the sound in my system because it was dark , dead, loose bass and smeared soundstage probably because of the loose bass. W/ the new platter the sound was livelier, bass was tighter and solid, open, wider soundstage and more vivid imaging. I think this new platter is very system dependent. It depends upon what your aiming or trying to achieve in your system. It work in my system to compensate. For my system's short comings.
Hope this helps,
