You are not alone. The human eye is surprisingly susceptible to even the smallest amounts of runout, and once you see it, you can never un-see it.
Good to hear I’m not the only one! It certainly took me a long time to find a Linn platter I was happy with, though that is accentuated by the suspension - any eccentricity will actually wobble the subchassis. I was always impressed by how good the Spacedeck was. That thing was absolutely spot on. My Garrard was really good too.
I would be interested in the belt you are testing, once you can share more details, as I am still struggling with the proper formulation for my drive system.
It originates from within the pfm community. I have no commercial involvement so not for me to announce, its maker can do so whenever he’s ready. The key benefit to my mind is it is the right size for the 50Hz TD-124 pulley (there will be two different belts). All other belts from day one attempt to be a compromise that work with both the 50 and smaller 60Hz pulleys. This always means they are just way too tight on the larger pulley which impacts the motor isolation, places unnecessarily side-force on the bearings and prematurely wears belts as they run stretched. It was a dumb design, there always should have been two distinct belts as the length is so different depending on the pulley in use (the theoretically ideal length differs by about 8-9mm, which is a lot over what is only a short belt). I’m holding out before fully commenting as really the key factor with a TD-124 belt is longevity; they run very fast (motor speed is about 1450rpm IIRC) and the tight ones always start to shed and get noisy after a while. So far this one is working very well indeed and I’ll likely stockpile some when they are ready. It is very quiet so far.
