I hope it works out for you. I hear a little pitch waver at times too, but I assumed this was due to living within 1/2km of 5 commuter rail lines, coupled with living in a 130yo house with bouncy floors. I could put the Sol on a wall shelf but it won't help much if the earth tremors from the trains are shaking the foundation. And sometimes its an edge warp on the record....can't do nothing about that. I never noticed this problem with the Delphi, but it has arguably the best suspension in the business....and a price to match. OTOH the extensively modified RB250 arm I had on it is not quite as revealing as the Sol arm - of music, never mind pitch waver. In the meantime, I'm still floating some ideas on improving motor isolation and stability. I'm working on the theory that the can is top heavy, causing any outside stimulus to bobble it back and forth under load at the pulley.
