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?

To get to a 1 volt level you will need to add 12db, which is easy with most tubes that might be in a gain stage.
