Does amp output V decrease by adding gain stage?

My tube amplifier is low sensitivity, has high output voltage at 4V. I plan to add one or two gain stages to improve the amp sensitivity. The question is by adding gain stages will that results in lowering output voltage?

IOW whatever it is rated at in terms of full output wattage will be the same. What you will change is the sensitivity of the amp. IOW you won't need 4 volts to get the amp to full output.
