Ring Clamps. What do you think?

First let me say that I have not had the opportunity to hear a ring clamp. At a $1000 list price it is not a top priority. It would seem to me that the whole concept would be detrimental to good sound. Like an acoustic guitar, a record needs to breathe. Weight and air play a vital role. I do use a record clamp, wouldn't be caught dead without it, but a heavy metal ring laying on top of my album holding it down doesn't appeal to me. I could be wrong.
