Nice system you have.
You can upgrade to a 9" JMW SIgnature reference arm with nordost and pair it with a new cartridge.
You can also upgrade to the 10" 3D arm. VPI will provide a mountboard adapter.
I have the same VPI Scoutmaster purchased new in the 90's and I am still rocking it. Upgraded over the years from JMW 9 to 9" SIg Reference and now the 10" 3D tonearm.
This Scoutmaster is one hell of a table. Built like a tank! I have no interest in replacing this table. I have it fully upgraded to the max with outboard flywheel belt and rim drives .. per HW himself in multiple conversations while i was upgrading my table over the years.. performance same level as SuperScoutmaster.
So go for it. Scoutmaster is one heck of a table!
