VPI Rim Drive vibrations

I found that the rubber feet on the SAMA motor assembly were causing slight vibration on my Super Scoutmaster with
Rimdrive. I placed 1 Symposium Acoustics Fat Pad below and in between each set of front and rear rubber footers below the motor assembly. Result was no more vibration and better sound- more solid, better soundstaging. Also replaced the mini-HRX feet below the table with Eden Sound Audio Bear Paws- again, better performance, as Stringreen noted above.

I have the Super Scoutmaster Reference with Rimdrive and Edensound Bearpaws. I get absolutely NO rocking of the tonearm- it is totally rock steady from the point the tonearm is lowered onto the record to the end of the record. I used the Fozgometer to adjust azimuth. This has completely eliminated any wobble I used to get when I adjusted azimuth without this device.

Krell,

I have the VPI SSM with rimdrive and Edensound Bear Paws which sit on a Symposium Acoustics Ultra shelf. I strongly recommend that you do NOT use the roller blocks under the Symposium Ultra shelf for your VPI SSM rimdrive. The Ultra shelf is superb, but you do not want any lateral movement which can cause problems with tonearm rocking which can be transmitted by the roller blocks. The roller blocks are excellent under a CD transport.

Here is something I just did which further improved my VPI Super Scoutmaster Ref. rimdrive's performance. I placed a round Symposium Acoustics coupler made of aircraft aluminum between the rubber feet on the SAMA- 1 front and 1 rear, which sits on a Symposium Acoustics Ultra Shelf. The sound further improved with more solid presentation, better staging, more stable.

No vibrations. I suspect that the rubber feet on the SAMA contributed somewhat to any possible vibrations I may have had before using the A.S. round couplers.

Krell303, I don't have any issues with vibrations from the rimdrive belt or anywhere else. The 10.5i tonearm is rocksteady when playing an LP- no wobbling. I use no special care or tool when putting on rimdrive belt. Make sure there is not too much pressure from the rimdrive belt against the platter. When turning off motor the platter should turn approx. 1 turn before stopping completely.

Krell, I put a small red sticky dot on the side of the center clamp. you can also put one on the side of the platter to count the number of revolutions. You do NOT want the tonearm to wobble which is GOOD. Do not adjust so the tonearm wobbles, adjust it so the platter stops after about 1 revolution or slightly more. It only takes minute changes in moving motor. Make sure motor is centered front and back between the side of the table and the gap between motor and side of table is equidistant. Your vibration problems should go away.

Mmerlionus, I found the Classic platter to be a big improvement over the Super Platter on my Super Scoutmaster Ref. with rim-drive, not only in sound but also in how more smoothly running the rim drive works.

Yes, I totally agree Stringreen!
