The RB1000 doesn't mount like an RB250/RB300 so I don't think it will mount on the Origin Live board. quoted from manual "It is fitted to the plinth by a 3-point fixing."
I had a Technics SL1210M5G and later moved to a table with an RB300. I prefer the Technics arm by a long shot over the rega arms.... GET KAB silcon damper for the Technics and rewire the arm... I sold my Technics to a friend and he put the damper on and it totally transformed the table.
or if you want to change arms you can get an SME mount and install and SME IV or something similar.
