Congratulations Shaw! The Rock is a very unique table, with a sound like no other. The 7 contains the Seismic Pod feet, so it has excellent isolation from the shelf it is placed upon. It requires no special considerations in set-up, except one: Do all your arm mounting and adjusting before filling the trough with damping fluid, and the same with cartridge alignment, tracking and anti-skate adjustments, as the silicone fluid is pretty heavy in viscosity.
Regarding the arm jacks, you can remove the XLR's and replace them with RCA's. KLEI and WBT are two of the best.
