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?

I made a terrible mistake. The INPUT voltage is 4 voltage. Very insensitive amps I got to say
That is RCA input. So the amp can mate with a giant preamp to take at least 4 Volt out to drive the amp. I am thinking to put gain stage(s) in the input of the amp. So the question is if I add gain stage(s) to the amp, does it mean the input voltage of the amp will reduce below 4 Volts?
Make perfect sense. Thanks gents
