I knew about this from Mike of VPI. I own a TNT VI w/superplatter and VPI IV Sama...(for 78s).
Motor noise is an irrelevant comment, baseless. The biggest problem I have is with the table isolation. I use a seismic sink under the tables which makes these tables top high end decks. Without the seismic sink, they are also rans. I haven't tried too many other products but on my stands its seismic sinks (Townsend) or forget it.
Harry purchased an expensive older and highly successful rim drive years ago and wondered how he could implement it into the VPI designs. It's not an experiment. Just as the superplatter is superior to the all acrylic platter. With the latest superplatter, it should be a cinch, remove the existing flywheel, reverse power leads on the two motors and no more belt replacements.
In early 2006, Mike sent me the new belts for the flywheel and platter which are thicker on the flywheel and thinner on the platter than in 2005. The earlier belts tended to waver (alot, .3 to .6 per hour on SDS). The newer belts hold their speed within .05 digits (adjusted for the first 20 minutes) then less than .01 digit change for hours and hours which I consider very stable indeed. Most of my friends use VPI tables or want to upgrade to a VPI from older high end tables.
Mike told me in July that the rim drive will tremendously increase bass solidity and dynamics while significantly improving speed stability and tonal balance. It's the tonal balance part that I have to hear to believe, the first two are a given as superior based on historical results of rim drives. The rim drive should be much less expensive than the superplatter.
The MusicDirect photo doesn't look right or doesn't fit because the RM is oversized and sitting under the platter. Later this week, VPI will provide answers on the retrofit.
