Oracle Delphi turntables - new Acrylic Mat and new Bearing - worth the money?


I have two Oracle Delphi turntables.  A Mk1 and a Mk2.

Has anyone upgraded an old Oracle Delphi with the new Bearing and the new Acrylic mat (they may not be brand new - but are part of MkVI).

I think they are $ 1,000 together.  Is it a worthwhile upgrade?  Thank you!!!
