Hey @drbond - the P8 is extremely light and the only thing that worked for me without counterweights was the Townshend Seismic platform that has pods screwed into the base. The very smallest pods are effective against the 10 pound turntable. If the pods are too inflexible, they won't do anything, and if they are too flexible they also won't do anything. The ones I use are just right - about 50% compression in the pods, and you don't have to adjust anything for position. They worked great for me.
Unfortunately, Max Townshend just passed away last week, so I am sure there will be some delays, but supposedly they have the capability to carry on. One frequent Audiogon poster I believe just started working there @millercarbon. You may want to reach out to him.
