I just recently purchased an outer ring clamp and heavy weight record clamp for my Clearaudio Maximum Solution table. The improvement was very noticeable and I recommend giving the outer ring clamp a try. My concern is that the 3.1 lb record clamp is too heavy and will damage the bearing. I have e-mailed Clearaudio and received no reply. I would like to get a few opinions on this concern regarding the 3.1 lb weight. Thanks.
