Put my in your book and have had a Clavis DC for over four years now and the silly thing will not wear out. It is in a Rockport Capella table and maybe it is the vacuum hold down or whatever that has kept it together all these years, but never got more than eight months out of a VdH.....Have two friends who have Helikons, but not the SL version and one of them replaced the Clavis DC with the Helikon and thought it was a nice improvement. The other friend had a Clearaudio Accurate and found the Helikon more to his liking.....They both run Rockport tables.
