-to eliminate a stage of gain.If you are really thinking of going with speakers that efficient that might be the way to go (if you don't mind working on the circuit).
It is also possible to rebias the 6SN7s by changing the cathode resistor to a larger value. You could reduce the gain by about 8-10 db this way without suffering too much sound-wise, but eliminating a stage of gain is *always* going to work the best, if you can.
