I don't see any real threat to a table owner's security regarding bearing friction or wear,providing it comes from a reliable,proven manufacturer.No problemo with any mentioned in these threads,as far as I'm concerned.
Just take a look at some of the "mega heavy platter" offerings on the market.Some going for big,bigger,biggest bucks.Though a heavier platter will most likely wear the bearing sooner,I haven't heard of many that do this for a "long time",and if the manufacturer is a responsible one,there's no problem in correcting it.
To my way of thinking,the "type of bearing" design should have a direct impact on perceived sound,along with a myriad of other parameters,obviously.Yet,since we are talking "bearings" my feelings are,that the best sounding bearing is "almost no bearing".Sort of!!Like a well designed opposing magnet design,for simplicity,in no friction.Or,a really great air bearing,which adds the "pain in the tush factor",like pumps and hosing,but will sound "fabs".You've got to go big bucks for the Walkers/Rockports/Continuum.As well as big "dough" for the Blue Pearl and Platine Verdiers of the world.I wish I had the money and "lazy day time" on my hands to simply play with all the stuff I've come to be a fan of.
This leaves a nice gap for the Galibers/Teres'/Sotas/Basis' to come into play.All great stuff!Simple and reliable goes a long way!
To me,the "table bearing issue" is likened to the "tonearm bearing issue".The closer you can get to "almost" no bearing,the better the sound "should" be.
It's been proven to me through listening,in arms,and this is why I love the better Air Bearing designs.Yet I am still willing to bet the house on very similar performance from the Schroder Ref,even though I may NEVER hear it.I just like it's design appeal,and there has been too many raves about it,to disbelieve any of it.
I already told my offspring I want my epitaph to read--"A fairly good tennis player,who NEVER heard a Schroder"!-:)
Yeah,I know I'm going overboard,but as I've mentioned in other posts,my system is getting updates,and won't be up for another month.I have little else to do,except to bug some of you.Sorry!!
Best!
