IIRC, the SME also lacks any real ability to adjust cartridge alignment angle. Again, cartridges aren't always perfect. Headshell holes instead of slots confer no sonic advantage, but they do make aligning an imperfect cartridge difficult or impossible.
To an SME headshell, applying a sharp 2.8mm (~ 7/64") bit *by hand* yields enough accomodation on the holes for any cartridge alignment I felt the need to make.
Wrt 'synergy', is this the sort of thing one can talk a table/arm out of or into? I suppose there is no harm in the trying. ;-) Yet when the makers of an arm and table are the same, the possibility may not be so remote as one might reason. Those who have heard seem to think there may be something to the combination of an SME table with an SME arm.
Cheers,
