You're right Paul, it is a tube buffer stage, not a tube output stage. Maybe the sonic difference is the better caps and diodes, who knows? I certainly cannot explain the benefits of a tube buffer stage, though I do know that Musical Fidelity made a lot of money selling outboard tube buffers.
It does sound pretty damn good though.
FWIW, I was joking. Simply enjoy your Marantz SA-11.
