I don't understand the objection to the wall mount, but perhaps your wife might not object to suspending the turntable from the ceiling using thin picture wire. I use 4 such wires to suspend an MDF board (easily leveled, using turnbuckles on the wires. The turntable (an Alexandria MkIV) is placed on the board. The effect is quite striking - it seems as if the turntable is suspended in air.
By locating the platform near a wall I keep it from floating all over the place by installing two small springs horizontally on the board edge to allow the platform to gentle rest against the wall.
the only vibration that can reach that setup is airborne and the turntable is at least 15 feet from the speakers. The suspending guy wires effectively serve as very low frequency pass filters.
