I would rewire the 309 as you could then compare (memory wise) any changes.
Eventually try the 3009R (comparing it to the 309) and decide if you want to upgrade the wiring as well.

SME 309 or SME 3009r?
I have both arms. My turntable is an Avid Sequel. My cartridge is a Benz LP. I want to rewire one of the arms, but don't know which would sound best. I currently have the 309 on the table so I know how that one performs. I've had the 3009r for quite sometime just sitting on a shelf. It's in terrific shape and the person who gave it to me, and has since passed away, thought it would outperform the 309. Does anyone have an informed opinion? Thanks.
