I have the Super Scoutmaster with Rimdrive and 10.5i arm fitted with a Lyra Titan-i. I upgraded from the original Super Scoutmaster, adding the superplatter, special feet, 10.5i arm, and rimdrive. This is a wonderful sounding package that I have no desire to replace. Each upgrade to full 'Super Scoutmaster Reference Rimdrive' has benefitted the musical performance.
I experienced the drive vibration that Buconero117 mentioned. Do not use the rimdrive on a Gingko platform- the tennis balls below transmit vibration and wobble. I use a Symposium Acoustics Ultra platform with excellent results. I noticed I still had some vibration after placing on this platform, and traced the problem to the rubber feet on the double motor. I inserted thin Symposium Acoustics Point Pods in between the feet front and rear feet so the feet are no longer touching the Symposium platform. This eliminated any vibration, wobble, and feedback to the platter. The rimdrive must be properly and carefully set up with the right amount of contact pressure on the superplatter. Once set up, it stays that way, and speed is constant at 33.3 using a Digistrobo on a tripod. Highly recommended!
